Chapter 7. Other application migration changes
This section describes additional changes that might be required for migrating an application from JBoss EAP 6.4 or 7.x to JBoss EAP 8.1-beta.
7.1. Web services application changes Copy linkLink copied to clipboard!
JBossWS 5 brings new features and performance improvements to JBoss EAP 7 web services, mainly through upgrades of the Apache CXF, Apache WSS4J, and Apache Santuario components. JBoss EAP 8.1 Beta then uses JBossWS 7 to support its features.
7.1.1. JAX-RPC support changes Copy linkLink copied to clipboard!
The Java API for XML-based RPC (JAX-RPC) was deprecated in Java EE 6 and was optional in Java EE 7. Starting with JBoss EAP 7, it is no longer supported. Applications that use JAX-RPC must be migrated to use Jakarta XML Web Services, which is the current Jakarta EE standard web services framework.
Use of JAX-RPC web services can be identified in any of the following ways:
-
The presence of a JAX-RPC mapping file, which is an XML file with the root element
<java-wsdl-mapping>. The presence of a
webservices.xmlXML descriptor file that contains a<webservice-description>element, which includes a<jaxrpc-mapping-file>child element. The following is an example ofwebservices.xmldescriptor file that defines a JAX-RPC web service.Copy to Clipboard Copied! Toggle word wrap Toggle overflow -
The presence of an
ejb-jar.xmlfile, which contains a<service-ref>that references a JAX-RPC mapping file.
7.1.2. Apache CXF Spring web services changes Copy linkLink copied to clipboard!
In previous releases of JBoss EAP, you could customize the JBossWS and Apache CXF integration by including a jbossws-cxf.xml configuration file with the endpoint deployment archive. One use case for this was to configure interceptor chains for web service client and server endpoints on the Apache CXF bus. This integration required Spring to be deployed in the JBoss EAP server.
Spring integration is no longer supported in JBoss EAP 8. Any application that contains a jbossws-cxf.xml descriptor configuration file must be modified to replace the custom configuration defined in that file. While it is still possible to directly access the Apache CXF API, be aware that the application will not be portable.
The suggested approach is to replace Spring custom configurations with the new JBossWS descriptor configuration options where possible. The JBossWS descriptor-based approach provides similar functionality without requiring modification of the client endpoint code. In some cases, you can replace Spring with Context Dependency Injection (CDI).
7.1.2.1. Apache CXF interceptors Copy linkLink copied to clipboard!
The JBossWS descriptor provides new configuration options that allow you to declare the interceptors without modifying the client endpoint code. Instead you declare interceptors within predefined client and endpoint configurations by specifying a list of interceptor class names for the cxf.interceptors.in and cxf.interceptors.out properties.
The following is an example of a jaxws-endpoint-config.xml file that declares interceptors using these properties.
7.1.2.2. Apache CXF features Copy linkLink copied to clipboard!
The JBossWS descriptor allows you to declare features within predefined client and endpoint configurations by specifying a list of feature class names for the cxf.features property.
The following is an example of a jaxws-endpoint-config.xml file that declares a feature using this property.
7.1.2.3. Apache CXF HTTP transport Copy linkLink copied to clipboard!
In Apache CXF, HTTP transport configuration is achieved by specifying org.apache.cxf.transport.http.HTTPConduit options. JBossWS integration allows conduits to be modified programmatically using the Apache CXF API as follows.
You can also control and override the Apache CXF HTTPConduit default values by setting system properties.
| Property | Type | Description |
|---|---|---|
| cxf.client.allowChunking | Boolean | Specifies whether to send requests using chunking. |
| cxf.client.chunkingThreshold | Integer | Sets the threshold at which switching from non-chunking to chunking mode. |
| cxf.client.connectionTimeout | Long | Sets the number of milliseconds for the connection timeout. |
| cxf.client.receiveTimeout | Long | Sets the number of milliseconds for the receive timeout. |
| cxf.client.connection | String |
Specifies whether to use the |
| cxf.tls-client.disableCNCheck | Boolean | Specifies whether to disable the CN host name check. |
7.1.3. WS-Security changes Copy linkLink copied to clipboard!
This section describes the various WS-Security changes for your application in JBoss EAP 6.4 and JBoss EAP 7.0.
-
If your application contains a custom callback handler that accesses the
org.apache.ws.security.WSPasswordCallbackclass, be aware that this class has moved to packageorg.apache.wss4j.common.ext. -
Most of the SAML bean objects from the
org.apache.ws.security.saml.extpackage have been moved to theorg.apache.wss4j.common.samlpackage. - Usage of the RSA v1.5 key transport and all related algorithms are disallowed by default.
-
The Security Token Service (STS) previously only validated
onBehalfOftokens. It now also validatesActAstokens. As a consequence, a valid username and password must be specified in theUsernameTokenthat is provided for theActAstoken. -
SAML Bearer tokens are now required to have an internal signature. The
org.apache.wss4j.dom.validate.SamlAssertionValidatorclass now has asetRequireBearerSignature()method to enable or disable the signature verification.
7.1.4. JBoss modules structure change Copy linkLink copied to clipboard!
The cxf-api and cxf-rt-core JARs have been merged into one cxf-core JAR. As a consequence, the org.apache.cxf module in JBoss EAP now contains the cxf-core JAR and exposes more classes than in the previous release.
7.1.5. Bouncy Castle requirements and changes Copy linkLink copied to clipboard!
If you want to use AES encryption with Galois/Counter Mode (GCM) for symmetric encryption in XML/WS-Security, you need the BouncyCastle Security Provider.
Starting with JBoss EAP 7, it was included with the org.bouncycastle module and JBossWS was able to rely on its class loader to get and use the BouncyCastle Security Provider. Therefore it is no longer necessary to statically install BouncyCastle in the current JVM. For applications running outside of the container, the security provider can be made available to JBossWS by adding a BouncyCastle library to the class path.
You can disable this behavior by setting the org.jboss.ws.cxf.noLocalBC property value to true in the jaxws-endpoint-config.xml deployment descriptor file for the server or the jaxws-client-config.xml descriptor file for clients.
If you want to use a different version than the one that ships with JBoss EAP, you can still statically install BouncyCastle to the JVM. In that case, the statically installed BouncyCastle Security Provider is chosen over the provider present in the class path. To avoid any issues, you must use BouncyCastle 1.72 or greater.
7.1.6. Apache CXF bus selection strategy Copy linkLink copied to clipboard!
The default bus selection strategy for clients running in-container has changed from THREAD_BUS to TCCL_BUS. For clients running out-of container, the default strategy is still THREAD_BUS. You can restore the behavior to that of the previous release by using either of the following methods.
-
Boot the JBoss EAP server with the system property
org.jboss.ws.cxf.jaxws-client.bus.strategyvalue set toTHREAD_BUS. - Explicitly set the selection strategy in the client code.
7.1.7. Jakarta XML Web Services 2.2 requirements for WebServiceRef Copy linkLink copied to clipboard!
Containers must use Jakarta XML Web Services 2.2 style constructors, which include the WebServiceFeature class as an argument in the constructor, to build clients that are injected into web service references. JBoss EAP 6.4, which ships with JBossWS 4, hides that requirement. Starting with JBoss EAP 7 that included JBossWS 5, this requirement is not hidden. This states that user provided service classes injected by the container must implement Jakarta XML Web Services 2.2 or later by updating the existing code to use the jakarta.xml.ws.Service constructor that includes one or more WebServiceFeature arguments.
protected Service(URL wsdlDocumentLocation,
QName serviceName,
WebServiceFeature... features)
protected Service(URL wsdlDocumentLocation,
QName serviceName,
WebServiceFeature... features)
7.1.8. IgnoreHttpsHost CN check change Copy linkLink copied to clipboard!
In previous releases, you could disable the HTTPS URL hostname check against a service’s Common Name (CN) given in its certificate by setting the system property org.jboss.security.ignoreHttpsHost to true. This system property name has been replaced with cxf.tls-client.disableCNCheck.
7.1.9. Server-side configuration and class loading Copy linkLink copied to clipboard!
As a consequence of enabling injections into service endpoint and service client handlers, it is no longer possible to automatically load handler classes from the org.jboss.as.webservices.server.integration JBoss module. If your application depends on a given predefined configuration, you might need to explicitly define new module dependencies for your deployment. For more information, see Migrate explicit module dependencies.
7.1.10. Deprecation of Java-endorsed standards override mechanism Copy linkLink copied to clipboard!
The Java-endorsed standards override mechanism was deprecated in JDK 1.8_40 with intent to remove it in JDK 9. This mechanism allowed developers to make libraries available to all deployed applications by placing JARs into an endorsed directory within the JRE.
Starting with the JBoss EAP 7 release, if your application used the JBossWS implementation of Apache CXF, it ensured that the required dependencies are added in the correct order and you should not be impacted by this change. If your application accesses Apache CXF directly, you must now provide the Apache CXF dependencies after the JBossWS dependencies as part of your application deployment.
7.1.11. Specification of descriptor in EAR archive Copy linkLink copied to clipboard!
In previous releases of JBoss EAP, you could configure the jboss-webservices.xml deployment descriptor file for Jakarta Enterprise Beans web service deployments in the META-INF/ directory of JAR archives or in the WEB-INF/ directory for POJO web service deployments and Jakarta Enterprise Beans web service endpoints bundled in WAR archives.
Starting with JBoss EAP 7, you can configure the jboss-webservices.xml deployment descriptor file in the META-INF/ directory of an EAR archive. If a jboss-webservices.xml file is found in the EAR archive and the JAR or WAR archive, the configuration data in the jboss-webservices.xml file for the JAR or WAR overrides the corresponding data in the EAR descriptor file.
7.2. Update the Remote URL connector and port Copy linkLink copied to clipboard!
Starting with JBoss EAP 7, the default connector has been changed from remote to http-remoting and the default remote connection port has changed from 4447 to 8080. The JNDI provider URL for the default configuration has changed from remote://localhost:4447 to http-remoting://localhost:8080.
7.3. Messaging application changes Copy linkLink copied to clipboard!
This section describes the various messaging application changes in JBoss EAP 7. In addition, you can learn more about how to:
- Change Jakarta Messaging deployment descriptors
- Update external Jakarta Messaging clients
- Replace deprecated address setting attributes
- Configure the required messaging application changes
7.3.1. Replace or update Jakarta Messaging deployment descriptors Copy linkLink copied to clipboard!
Starting with JBoss EAP 7, the proprietary HornetQ messaging resource deployment descriptor files identified by the naming pattern -jms.xml does not work. The following is an example of a Java Message Service resource deployment descriptor file in JBoss EAP 6:
If you used -jms.xml Java Message Service deployment descriptors in your application in the previous release, you can either convert your application to use the standard deployment descriptor as specified in the Resource Definition and Configuration section of the Jakarta EE platform, or you can update the deployment descriptor to use the messaging-activemq-deployment schema instead. If you choose to update the descriptor, you need to make the following modifications:
- Change the namespace from "urn:jboss:messaging-deployment:1.0" to "urn:jboss:messaging-activemq-deployment:1.0".
-
Change the
<hornetq-server>element name to<server>.
The modified file should look like the following example.
7.3.2. Replace the HornetQ API Copy linkLink copied to clipboard!
JBoss EAP 6 included the org.hornetq module, which allowed you to use the HornetQ API in your application source code.
Apache ActiveMQ Artemis replaces HornetQ in JBoss EAP 7, so you must migrate any code that used the HornetQ API to use the Apache ActiveMQ Artemis API. The libraries for this API are included in the org.apache.activemq.artemis module.
ActiveMQ Artemis is an evolution of HornetQ, so many of the concepts still apply.
7.3.3. Replace Deprecated Address Setting Attributes Copy linkLink copied to clipboard!
The ability to auto-create and auto-delete topics and queues using the auto-create-jms-queues, auto-delete-jms-queues, auto-create-jms-topics, and auto-delete-jms-topics attributes was only partially implemented and not fully configurable in JBoss EAP 7. These attributes, which are deprecated, were provided as a technology preview feature only and were not supported.
You must replace any usage of these deprecated attributes with the following replacement attributes.
The deprecated attributes no longer configure this functionality since JBoss EAP 8.0 and do not take effect. The replacement attributes are not supported either. They are provided only as a way to migrate on the best effort basis.
| Deprecated Attribute | Replacement Attribute |
|---|---|
| auto-create-jms-queues | auto-create-queues |
| auto-delete-jms-queues | auto-delete-queues |
| auto-create-jms-topics | auto-create-addresses |
| auto-delete-jms-topics | auto-delete-addresses |
In JBoss EAP 6, the default address setting attributes were set to false. Starting with JBoss EAP 7, the replacement attributes are set to true by default.
If you prefer to preserve the JBoss EAP 6 behavior, you must set the replacement attributes to false.
For more information about these replacement attributes, see Address Setting Attributes in the JBoss EAP 7.4 Configuring Messaging Guide.
7.3.4. Messaging application changes required for JBoss EAP 7 Copy linkLink copied to clipboard!
Starting with JBoss EAP 7.2, if a client application directly depends on Artemis client JARs, for example, artemis-jms-client, artemis-commons, artemis-core-client, or artemis-selector, then you must add the following dependency in your pom.xml file for wildfly-client-properties.
<dependency> <groupId>org.jboss.eap</groupId> <artifactId>wildfly-client-properties</artifactId> </dependency>
<dependency>
<groupId>org.jboss.eap</groupId>
<artifactId>wildfly-client-properties</artifactId>
</dependency>
This is to avoid a JMSRuntimeException when calling message.getJMSReplyTo() from an older JBoss EAP 7 client as described in JBEAP-15889.
7.4. Jakarta RESTful Web Services and RESTEasy application changes Copy linkLink copied to clipboard!
JBoss EAP 6 bundled RESTEasy 2, which was an implementation of JAX-RS 1.x.
JBoss EAP 8 and JBoss EAP 7.1 included RESTEasy 3.0.x, which is an implementation of JAX-RS 2.0 as defined by the JSR 339: JAX-RS 2.0: The Java API for RESTful Web Services specification.
JBoss EAP 8.0 includes RESTEasy 3.15, which is an implementation of Jakarta RESTful Web Services 2.1. This release also adds support for JDK 11. While providing some of the RESTEasy 4 key features, this release is based on RESTEasy 3.0, ensuring full backward compatibility. As a result, you should encounter few issues when migrating from RESTEasy 3.0 to RESTEasy 3.15. For more information about the Java API for RESTEasy RESTEasy 3.15, see RESTEasy Jakarta RESTful Web Services 3.15.0.Final API.
JBoss EAP 8.1 Beta provides support for RESTEasy 6.2, which implements the Jakarta RESTful Web Services 3.1 specification.
If you are migrating from JBoss EAP 6.4, be aware that the version of Jackson included in JBoss EAP has changed. JBoss EAP 6.4 included Jackson 1.9.9. JBoss EAP 7 and later now include Jackson 2.6.3 or greater.
This section describes how these changes might impact applications that use RESTEasy or Jakarta RESTful Web Services.
7.4.1. RESTEasy deprecated classes Copy linkLink copied to clipboard!
Interceptor and MessageBody Classes
JSR 311: JAX-RS: The Java™ API for RESTful Web Services did not include an interceptor framework, so RESTEasy 2 provided one. JSR 339: JAX-RS 2.0: The Java API for RESTful Web Services introduced an official interceptor and filter framework, so the interceptor framework included in RESTEasy 2 is now deprecated, and was replaced by the Jakarta REST compliant interceptor facility in RESTEasy 3.x. The relevant interfaces are defined in the jakarta.ws.rs.ext package of the jakarta.ws.rs.api module.
The following providers have been removed in JBoss EAP 8.0:
-
org.jboss.resteasy:resteasy-jackson-provider -
org.jboss.resteasy:resteasy-jettison-provider -
org.jboss.resteasy:resteasy-yaml-provider
The following has been removed in JBoss EAP 8.0 as they now have Jakarta RESTful Web Services replacements.
-
@Suspendandorg.jboss.resteasy.spi.AsynchronousResponsehave been removed and replaced with@Suspendedandjavax.ws.rs.container.AsyncResponserespectively. -
StringConverteris replaced by aParamConverter. -
org.jboss.resteasy.plugins.providers.SerializableProviderwas deprecated and has been removed. The following interceptor interfaces deprecated in RESTEasy 3.x has been removed.
-
The
org.jboss.resteasy.spi.interception.PreProcessInterceptorinterface was replaced by thejakarta.ws.rs.container.ContainerRequestFilterinterface in RESTEasy 3.x. The following interfaces and classes have been removed from RESTEasy 3.x and JBoss EAP 8.0.
-
org.jboss.resteasy.spi.interception.MessageBodyReaderInterceptor -
org.jboss.resteasy.spi.interception.MessageBodyWriterInterceptor -
org.jboss.resteasy.spi.interception.MessageBodyWriterContext -
org.jboss.resteasy.spi.interception.MessageBodyReaderContext -
org.jboss.resteasy.core.interception.InterceptorRegistry -
org.jboss.resteasy.core.interception.InterceptorRegistryListener -
org.jboss.resteasy.core.interception.ClientExecutionContextImpl
-
-
The
org.jboss.resteasy.spi.interception.MessageBodyWriterInterceptorinterface was replaced by thejakarta.ws.rs.ext.WriterInterceptorinterface. In addition, some changes to the
jakarta.ws.rs.ext.MessageBodyWriterinterface might not be backward compatible with respect to JAX-RS 1.x. If your application used JAX-RS 1.x, review your application code to make sure you define@Producesor@Consumesfor your endpoints. Failure to do so might result in an error similar to the following.org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: <OBJECT> of media type:
org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: <OBJECT> of media type:Copy to Clipboard Copied! Toggle word wrap Toggle overflow The following is an example of a REST endpoint that can cause this error.

All interceptors from the previous release of RESTEasy can run in parallel with the new Jakarta REST filter and interceptor interfaces.
Client API
The RESTEasy client framework in resteasy-jaxrs was replaced by the JAX-RS 2.0 compliant resteasy-client module in JBoss EAP 7.0. As a result, some RESTEasy client API classes and methods are deprecated.
The following classes have been removed from JBoss EAP 8.0.
-
The
org.jboss.resteasy.client.ClientResponseFailureexception and theorg.jboss.resteasy.client.ClientExecutorandorg.jboss.resteasy.client.EntityTypeFactoryinterfaces are also deprecated. You must replace the
org.jboss.resteasy.client.ClientRequestandorg.jboss.resteasy.client.ClientResponseclasses withorg.jboss.resteasy.client.jaxrs.ResteasyClientandjakarta.ws.rs.core.Responserespectively.The following is an example of how to send a link header with the RESTEasy client in RESTEasy 2.3.x.
ClientRequest request = new ClientRequest(generateURL("/linkheader/str")); request.addLink("previous chapter", "previous", "http://example.com/TheBook/chapter2", null); ClientResponse response = request.post(); LinkHeader header = response.getLinkHeader();ClientRequest request = new ClientRequest(generateURL("/linkheader/str")); request.addLink("previous chapter", "previous", "http://example.com/TheBook/chapter2", null); ClientResponse response = request.post(); LinkHeader header = response.getLinkHeader();Copy to Clipboard Copied! Toggle word wrap Toggle overflow The following is an example of how to accomplish the same task with the RESTEasy client in RESTEasy 3.
ResteasyClient client = new ResteasyClientBuilder().build(); Response response = client.target(generateURL("/linkheader/str")).request() .header("Link", "<http://example.com/TheBook/chapter2>; rel=\"previous\"; title=\"previous chapter\"").post(Entity.text(new String())); jakarta.ws.rs.core.Link link = response.getLink("previous");ResteasyClient client = new ResteasyClientBuilder().build(); Response response = client.target(generateURL("/linkheader/str")).request() .header("Link", "<http://example.com/TheBook/chapter2>; rel=\"previous\"; title=\"previous chapter\"").post(Entity.text(new String())); jakarta.ws.rs.core.Link link = response.getLink("previous");Copy to Clipboard Copied! Toggle word wrap Toggle overflow See the
resteasy-jaxrs-clientquickstart for an example of an external Jakarta REST RESTEasy client that interacts with a Jakarta REST Web service.-
The classes and interfaces in the
org.jboss.resteasy.client.cachepackage are also deprecated. They are replaced by equivalent classes and interfaces in theorg.jboss.resteasy.annotations.cachepackage.
For more information about the org.jboss.resteasy.client.jaxrs API classes, see the RESTEasy Jakarta REST JavaDoc.
StringConverter
The org.jboss.resteasy.spi.StringConverter class is deprecated in RESTEasy 3.x and JBoss EAP 8.0. This functionality can be replaced using the Jakarta REST jakarta.ws.rs.ext.ParamConverterProvider class.
7.4.2. Removed or Protected RESTEasy classes Copy linkLink copied to clipboard!
ResteasyProviderFactory Add methods
Most of the org.jboss.resteasy.spi.ResteasyProviderFactory add() methods have been removed or made protected in RESTEasy 3.0. For example, the addBuiltInMessageBodyReader() and addBuiltInMessageBodyWriter() methods have been removed and the addMessageBodyReader() and addMessageBodyWriter() methods have been made protected.
You should now use the registerProvider() and registerProviderInstance() methods.
Additional Classes Removed From RESTEasy 3
The @org.jboss.resteasy.annotations.cache.ServerCached annotation, which specified the response to the Jakarta REST method should be cached on the server, was removed from RESTEasy 3 and must be removed from the application code.
7.4.3. Additional RESTEasy changes Copy linkLink copied to clipboard!
This section provides information about some additional changes in RESTEasy for JBoss EAP.
SignedInput and SignedOuput
-
SignedInputandSignedOutputforresteasy-cryptomust have theContent-Typeset tomultipart/signedin either theRequestorResponseobject, or by using the@Consumesor@Producesannotation. -
You can use
SignedOutputandSignedInputto return theapplication/pkcs7-signatureMIME type format in binary form by setting that type in the@Producesor@Consumesannotations. -
If the
@Producesor@Consumesistext/plainMIME type,SignedOutputwill be base64 encoded and sent as a String.
Security Filters
The security filters for @RolesAllowed, @PermitAll, and @DenyAll now return "403 Forbidden" instead of "401 Unauthorized".
Client-side Filters
The client-side filters that were introduced in JAX-RS 2.0 will not be bound and run when you are using the RESTEasy client API from a release prior to RESTEasy 3.0.
Asynchronous HTTP Support
Because the JAX-RS 2.0 specification added asynchronous HTTP support using the @Suspended annotation and the AsynResponse interface, the RESTEasy proprietary API for asynchronous HTTP was deprecated and might be removed in a future RESTEasy release. The asynchronous Tomcat and asynchronous JBoss Web modules have also been removed from the server installation. If you are not using the Servlet 3.0 container or higher, asynchronous HTTP server-side processing will be simulated and run synchronously in same request thread.
Server-side Cache
Server-side cache setup has changed. Please see the RESTEasy Documentation for more information.
YAML Provider Setting Changes
In previous releases of JBoss EAP, the RESTEasy YAML provider setting was enabled by default. This has changed in JBoss EAP 7. The YAML provider is now disabled by default. Its use is not supported due to a security issue in the SnakeYAML library used by RESTEasy for unmarshalling and it must be explicitly enabled in the application. For information about how to enable the YAML provider in your application and add the Maven dependencies, see YAML Provider in JBoss EAP 8.0 Developing Web Services Applications.
Default Charset UTF-8 in Content-Type Header
As of JBoss EAP 7.1, the resteasy.add.charset parameter is set to true by default. You can set the resteasy.add.charset parameter to false if you do not want RESTEasy to add charset=UTF-8 to the returned content-type header when the resource method returns a text/* or application/xml* media type without an explicit charset.
For more information about text media types and character sets, see Text Media Types and Character Sets in JBoss EAP 7.4 Developing Web Services Applications.
SerializableProvider
Deserializing Java objects from untrusted sources is not safe. For this reason, starting with JBoss EAP 7, the org.jboss.resteasy.plugins.providers.SerializableProvider class is disabled by default, and it is not recommended to use this provider.
Matching Requests to Resource Methods
In RESTEasy 3, improvements and corrections were made to the implementation of matching rules, as defined in the JAX-RS specification. In particular, a change was made to how an ambiguous URI on a sub-resource method and a sub-resource locator is handled.
In RESTEasy 2, it was possible for a sub-resource locator to execute successfully even when there was another sub-resource with the same URI. This behavior was incorrect according to the specification.
In RESTEasy 3, when there is an ambiguous URI for a sub-resource and a sub-resource locator, calling the sub-resource will be successful; however, calling the sub-resource locator will result in an HTTP status 405 Method Not Allowed error.
The following example contains an ambiguous @Path annotation on a sub-resource method and a sub-resource locator. Notice that the URI to both endpoints, anotherResource and anotherResourceLocator, is the same. The difference between the two endpoints is that the anotherResource method is associated with the REST verb, POST. The anotherResourceLocator method is not associated with any REST verb. According to the specification, the endpoint with the REST verb, in this case the anotherResource method, will always be selected.
7.4.4. RESTEasy SPI changes Copy linkLink copied to clipboard!
The RESTEasy SPI provider has been removed in JBoss EAP 8.
SPI Exceptions
All SPI failure exceptions were deprecated and are no longer used internally. They have been replaced with the corresponding Jakarta REST exception.
| Deprecated Exception | Replacement Exception in jaxrs-api module |
|---|---|
| org.jboss.resteasy.spi.ForbiddenException | jakarta.ws.rs.ForbiddenException |
| org.jboss.resteasy.spi.MethodNotAllowedException | jakarta.ws.rs.NotAllowedException |
| org.jboss.resteasy.spi.NotAcceptableException | jakarta.ws.rs.NotAcceptableException |
| org.jboss.resteasy.spi.NotFoundException | jakarta.ws.rs.NotFoundException |
| org.jboss.resteasy.spi.UnauthorizedException | jakarta.ws.rs.NotAuthorizedException |
| org.jboss.resteasy.spi.UnsupportedMediaTypeException | jakarta.ws.rs.NotSupportedException |
InjectorFactory and Registry
The InjectorFactory and Registry SPIs have changed. This should not be an issue if you use RESTEasy as documented and supported.
7.4.5. Jackson provider changes Copy linkLink copied to clipboard!
The version of Jackson included in JBoss EAP 6.4 has changed. Starting with JBoss EAP 7, the Jackson provider has changed from resteasy-jackson-provider to resteasy-jackson2-provider.
The upgrade to the resteasy-jackson2-provider requires some package changes. For example, the Jackson annotation package has changed from org.codehaus.jackson.annotate to com.fasterxml.jackson.annotation.
7.4.6. Spring RESTEasy integration changes Copy linkLink copied to clipboard!
JBoss EAP 8.1 Beta provides support for RESTEasy 6.2. If you plan to use the Spring 6.0 framework with JBoss EAP 8.1 Beta, you must use Java 17.
The Spring 4.0 framework introduced support for Java 8. If you plan to use the RESTEasy 3.x integration with Spring, be sure to specify 4.2.x as the minimum Spring version in your deployment as this is the earliest stable version supported by JBoss EAP 7.
7.4.7. RESTEasy Jettison JSON provider changes Copy linkLink copied to clipboard!
The RESTEasy Jettison JSON provider is deprecated since JBoss EAP 7 and is no longer added to deployments by default. You are encouraged to switch to the recommended RESTEasy Jackson provider. If you prefer to continue to use the Jettison provider, you must define an explicit dependency for it in the jboss-deployment-descriptor.xml file as demonstrated in the following example.
For more information about how to define explicit dependencies, see Add an Explicit Module Dependency to a Deployment in the JBoss EAP 7.4 Development Guide.
7.4.8. MicroProfile for JBoss EAP Copy linkLink copied to clipboard!
MicroProfile is the name of a specification that developers can use to configure applications and microservices to run in multiple environments without having to modify or repackage those apps. Previously, MicroProfile was available for JBoss EAP 7.3 as a technology preview, but it has since been removed. MicroProfile is now available only on JBoss EAP XP.
7.5. CDI application changes Copy linkLink copied to clipboard!
JBoss EAP 8.0 includes support for CDI 4.0. As a result, applications written using older CDI releases might see some changes in behavior when migrating to JBoss EAP 8.0. This section summarizes only a few of these changes.
For more information about Weld and CDI 4.0, see:
7.5.1. Bean Archives Copy linkLink copied to clipboard!
Bean classes of enabled beans must be deployed in bean archives to ensure they are discovered by CDI and processed as beans.
CDI 1.1 introduced implicit bean archives, which are archives that contain one or more bean classes with a bean defining annotation, or one or more session beans. Implicit bean archives are scanned by CDI and, during type discovery, only classes with bean defining annotations are discovered. For more information, see Type and Bean Discovery in JSR 365: Contexts and Dependency Injection for Java™ 2.0. The Jakarta equivalents for bean defining annotations are defined in the Jakarta Context Dependency Injection 2.0 specification.
In CDI 4.0:
- An archive does not differentiate whether beans.xml has a version number.
- In addition to build-compatible extensions, an archive also contains archives without the beans.xml file. The build compatible extensions are not bean archives.
-
The default discovery mode of an archive with an empty beans.xml file is set to
annotatedinstead ofall. For example, if thebeans.xmlfile is empty, it is an implicit bean archive instead of an explicit bean archive. -
In both cases, the bean discovery element is unaffected between archives with and without
beans.xmlfiles.
For more information about CDI 4.0, see Jakarta Contexts and Dependency Injection 4.0.
A bean archive has a bean discovery mode of all, annotated or none. A bean archive which contains non-empty beans.xml must specify the bean-discovery-mode attribute. The default value for the attribute is annotated.
An archive is not a bean archive in the following cases:
-
It contains a
beans.xmlfile with abean-discovery-modeofnone. -
It contains a portable extension or a build compatible extension and no
beans.xmlfile.
An archive is an explicit bean archive in the following case:
-
The archive contains a
beans.xmlfile withbean-discovery-modeofall.
An archive is an implicit bean archive in the following cases:
- The archive contains a beans.xml file that is empty.
-
The archive contains one or more bean classes with a bean defining annotation, or one or more session beans, even if it does not contain a
beans.xmlfile.
CDI 1.2 limited bean defining annotations to the following:
-
@ApplicationScoped,@SessionScoped,@ConversationScoped, and@RequestScopedannotations - All other normal scope types
-
@Interceptorand@Decoratorannotations -
All stereotype annotations, which are annotations annotated with
@Stereotype -
@Dependentscope annotation
7.5.2. Clarification of Conversation Resolution Copy linkLink copied to clipboard!
The conversation context lifecycle was changed in CDI 1.2 to prevent conflicts with the Servlet specification as described in CDI Specification Issue CDI-411. The conversation scope is active during all servlet requests and should not prevent other servlets or servlet filters from setting the request body or character encoding. For more information, see Conversation context lifecycle in Jakarta EE.
7.5.3. Observer Resolution Copy linkLink copied to clipboard!
Event resolution was partly rewritten in CDI 1.2. In CDI 1.0, an event is delivered to an observer method if the observer method has all the event qualifiers. In CDI 1.2, an event is delivered to an observer method if the observer method has no event qualifiers or has a subset of the event qualifiers. For more information, see Observer resolution.
7.6. HTTP Session ID change Copy linkLink copied to clipboard!
The string returned by the request.getSession().getId() call to get the unique identifier assigned to an HTTP session has changed between JBoss EAP 6.4 and JBoss EAP 7.
JBoss EAP 6.4 returned both the session ID and the instance ID in the session-id.instance-id format.
JBoss EAP 7 and EAP 8 returns only the session ID.
This change can create issues with routeless cookies for some upgrades from JBoss EAP 6 to JBoss EAP 8. If your application recreates JSESSIONID cookies based upon the return value from this method call, you might need to update the application code to provide the desired behavior.
7.7. Migrate explicit module dependencies Copy linkLink copied to clipboard!
The introduction of the modular class loading system and JBoss Modules in the previous release of JBoss EAP allowed for fine-grained control of the classes available to applications. This feature allowed you to configure explicit module dependencies using the application’s MANIFEST.MF file or the jboss-deployment-structure.xml deployment descriptor file.
If you defined explicit module dependencies in your application, you should be aware of the following changes in JBoss EAP 7.
Review Dependencies for Availability
The modules that are included in JBoss EAP have changed. When you migrate your application to JBoss EAP 7, review your MANIFEST.MF and jboss-deployment-structure.xml file entries to make sure they do not refer to any modules that were removed or are deprecated in this release of the product.
Dependencies That Require Annotation Scanning
In the previous release of JBoss EAP, if your dependency contained annotations that needed to be processed during annotation scanning, such as when declaring EJB Interceptors, you were required to generate and include a Jandex index in a new JAR file and then set a flag in the MANIFEST.MF or jboss-deployment-structure.xml deployment descriptor file.
JBoss EAP 7 now provides automatic runtime generation of annotation indexes for static modules, so you no longer need to generate them manually. However, you still need to add the annotations flag to the application’s MANIFEST.MF file or the jboss-deployment-structure.xml deployment descriptor file as demonstrated below.
Example: Annotation Flag in the MANIFEST.MF File
Dependencies: com.company.my-ejb annotations, com.company.other
Dependencies: com.company.my-ejb annotations, com.company.other
Example: Annotation Flag in the jboss-deployment-structure.xml File
7.8. Hibernate changes Copy linkLink copied to clipboard!
JBoss EAP 8 includes support for Hibernate ORM 6.2, an object-relational mapping tool for the Java programming language. For more information about the Hibernate ORM 6.2 documentation, see Hibernate ORM 6.2.
When migrating from JBoss EAP 7.4 to JBoss EAP 8.1 Beta, refer to the specific Hibernate ORM migration documentation for your Hibernate ORM version.
For migrating from JBoss EAP 8.0 to JBoss EAP 8.1 Beta, you must complete the following steps:
For migrating from JBoss EAP 7.4 to JBoss EAP 8.1 Beta, you must also complete the following steps:
- Migrating from Hibernate ORM 5.3 to 6.2
- Hibernate ORM dialects
- Deprecated Hibernate ORM classes
- Incubating Hibernate ORM classes
- Hibernate ORM internals
For migrating from older versions of JBoss EAP and Hibernate, you must also complete the following steps.
7.8.1. Migrating from Hibernate ORM 6.2 to 6.6 Copy linkLink copied to clipboard!
JBoss EAP 8.1 Beta includes Hibernate ORM 6.6. For more information about the changes implemented between Hibernate ORM 6.2 and Hibernate ORM 6.6, see the following Hibernate migration guides:
7.8.2. Migrating from Hibernate ORM 5.3 to 6.2 Copy linkLink copied to clipboard!
JBoss EAP 7.4 included Hibernate ORM 6.2. For more information about the changes implemented between Hibernate ORM 5.3 and Hibernate ORM 6.2, see the following Hibernate migration guides:
7.8.3. Migrating from Hibernate ORM 4.3 to Hibernate ORM 5.0 Copy linkLink copied to clipboard!
JBoss EAP 7.0 included Hibernate ORM 5.0. This section highlights the changes you need to make when migrating from Hibernate ORM version 4.3 to version 5. For more information about the changes implemented between Hibernate ORM 4 and Hibernate ORM 5, see the Hibernate ORM 5.0 Migration Guide.
Removed and deprecated classes
The following deprecated classes were removed from Hibernate ORM 5:
Other changes to classes and packages
-
The
org.hibernate.integrator.spi.Integratorinterface changed to account for bootstrap redesign. -
A new package
org.hibernate.engine.jdbc.env.spiwas created. It contains theorg.hibernate.engine.jdbc.env.spi.JdbcEnvironmentinterface, which was extracted from theorg.hibernate.engine.jdbc.spi.JdbcServicesinterface. -
A new
org.hibernate.boot.model.relational.ExportableProducerinterface was introduced that will affectorg.hibernate.id.PersistentIdentifierGeneratorimplementations. -
The signature of
org.hibernate.id.Configurablewas changed to acceptorg.hibernate.service.ServiceRegistryrather than justorg.hibernate.dialect.Dialect. -
The
org.hibernate.metamodel.spi.TypeContributorinterface has migrated toorg.hibernate.boot.model.TypeContributor. -
The
org.hibernate.metamodel.spi.TypeContributionsinterface has migrated toorg.hibernate.boot.model.TypeContributions.
Type handling
-
Built-in
org.hibernate.type.descriptor.sql.SqlTypeDescriptorimplementations no longer auto-register themselves withorg.hibernate.type.descriptor.sql.SqlTypeDescriptorRegistry. Applications using customSqlTypeDescriptorimplementations that extend the built-in implementations and rely on that behavior must be updated to callSqlTypeDescriptorRegistry.addDescriptor()themselves. -
For IDs defined as generated UUIDs, some databases require you to explicitly set the
@Column(length=16)in order to generateBINARY(16)so that comparisons work properly. -
For
EnumTypemappings defined in thehbm.xml, where you wantjavax.persistence.EnumType.STRINGname-mapping, this configuration must be explicitly stated by using either theuseNamed(true)setting or by specifying a VARCHAR value of12.
Transaction management
-
The transaction SPI underwent a major redesign in Hibernate ORM 5. In Hibernate ORM 4.3, you used the
org.hibernate.TransactionAPI to directly access different back-end transaction strategies. Hibernate ORM 5 introduced a level of indirection. On the back end, theorg.hibernate.Transactionimplementation now talks to aorg.hibernate.resource.transaction.TransactionCoordinator, which represents the transactional context for a given session according to the back-end strategy. While this does not have a direct impact on developers, it could affect the bootstrap configuration. Previously applications would specifyhibernate.transaction.factory_classproperty, which is now deprecated, and refer to aorg.hibernate.engine.transaction.spi.TransactionFactoryFQN (fully qualified name). With Hibernate ORM 5, you specify thehibernate.transaction.coordinator_classsetting and refer to aorg.hibernate.resource.transaction.TransactionCoordinatorBuilder. Seeorg.hibernate.cfg.AvailableSettings.TRANSACTION_COORDINATOR_STRATEGYfor additional details. The following short names are now recognized:
-
jdbc: Manage transactions using the JDBC
java.sql.Connection. This is the default for non-Jakarta Persistence transactions. jta: Manage transactions using Jakarta Transactions.
ImportantIf a Jakarta Persistence application does not provide a setting for the
hibernate.transaction.coordinator_classproperty, Hibernate will automatically build the proper transaction coordinator based on the transaction type for the persistence unit.If a non-Jakarta Persistence application does not provide a setting for the
hibernate.transaction.coordinator_classproperty, Hibernate will default tojdbcto manage the transactions. This default will cause problems if the application actually uses Jakarta Transactions. A non-Jakarta Persistence application that uses Jakarta Transactions should explicitly set thehibernate.transaction.coordinator_classproperty value tojtaor provide a customorg.hibernate.resource.transaction.TransactionCoordinatorBuilderthat builds aorg.hibernate.resource.transaction.TransactionCoordinatorthat properly coordinates with Jakarta Transactions.
-
jdbc: Manage transactions using the JDBC
Other Hibernate ORM 5 changes
-
The
cfg.xmlfiles are again fully parsed and integrated with events, security, and other functions. -
The properties loaded from the
cfg.xmlusing theEntityManagerFactorydid not previously prefix names withhibernate. This has now been made consistent. - The configuration is no longer serializable.
-
The
org.hibernate.dialect.Dialect.getQuerySequencesString()method now retrieves catalog, schema, and increment values. -
The
AuditConfigurationmodifier was removed fromorg.hibernate.envers.boot.internal.EnversService. -
The
AuditStrategymethod parameters were changed to remove the obsoleteAuditConfigurationand use the newEnversService. -
Various classes and interfaces in the
org.hibernate.hql.spipackage and subpackages have been moved to the neworg.hibernate.hql.spi.idpackage. This includes theMultiTableBulkIdStrategyclass and theAbstractTableBasedBulkIdHandler,TableBasedDeleteHandlerImpl, andTableBasedUpdateHandlerImplinterfaces and their subclasses. - There was a complete redesign of property access contracts.
-
Valid
hibernate.cache.default_cache_concurrency_strategysetting values are now defined using theorg.hibernate.cache.spi.access.AccessType.getExternalName()method rather than theorg.hibernate.cache.spi.access.AccessTypeenum constants. This is more consistent with other Hibernate settings.
7.8.4. Migrating from Hibernate ORM 5.0 to Hibernate ORM 5.1 Copy linkLink copied to clipboard!
JBoss EAP 7.1 included Hibernate ORM 5.1. This section highlights the differences and the changes needed when migrating from Hibernate ORM version 5.0 to version 5.1.
Hibernate ORM 5.1 features
This release of Hibernate includes performance improvements and bug fixes. For more information, see Hibernate ORM 5.1 Features in the JBoss EAP Release notes for 7.1.0. For additional information about the changes implemented between Hibernate ORM 5.0 and Hibernate ORM 5.1, see the Hibernate ORM 5.1 Migration Guide.
Schema management tooling changes
Schema management tooling changes in JBoss EAP 7
Schema management tooling changes in Hibernate ORM 5.1 are focused on the following areas:
-
Unifying the handling of
hbm2ddl.autoand support for hibernate’s Jakarta Persistenceschema-generation. - Removing JDBC concerns from the SPI to facilitate true replacement for Hibernate OGM, a persistence engine that provides Jakarta Persistence support for NoSQL data stores.
The schema management tooling changes are only a migration concern for applications that directly use the following classes:
-
org.hibernate.tool.hbm2ddl.SchemaExport -
org.hibernate.tool.hbm2ddl.SchemaUpdate -
org.hibernate.tool.hbm2ddl.SchemaValidator -
org.hibernate.tool.schema.spi.SchemaManagementTool, or its delegates
Schema management tooling changes in JBoss EAP 7.1
Hibernate ORM 5.1.10, included in JBoss EAP 7.1, introduced a strategy for retrieving database tables that improve SchemaMigrator and SchemaValidator performance. This strategy executes a single java.sql.DatabaseMetaData#getTables(String, String, String, String[]) call to determine if each javax.persistence.Entity has a mapped database table. This is the default strategy, and it uses the hibernate.hbm2ddl.jdbc_metadata_extraction_strategy=grouped property setting. This strategy might require hibernate.default_schema and/or hibernate.default_catalog to be provided.
To use the old strategy of executing a java.sql.DatabaseMetaData#getTables(String, String, String, String[]) call for each javax.persistence.Entity, use the hibernate.hbm2ddl.jdbc_metadata_extraction_strategy=individually property setting.
7.8.5. Migrating from Hibernate ORM 5.1 and Hibernate ORM 5.2 to Hibernate ORM 5.3 Copy linkLink copied to clipboard!
JBoss EAP 7.4 includes Hibernate ORM 5.3. This section highlights some of the changes needed when migrating from Hibernate ORM 5.1 to Hibernate ORM 5.2 and then to Hibernate ORM 5.3.
Hibernate ORM 5.2 features
Hibernate ORM 5.2 is built using the Java 8 JDK and requires the Java 8 JRE at runtime. The following is a list of some of the changes made in this release:
-
The
hibernate-java8module was merged intohibernate-core, and the Java 8 date/time datatypes are now natively supported. -
The
hibernate-entitymanagermodule was merged intohibernate-core.HibernateEntityManagerandHibernateEntityManagerFactoryare deprecated. -
The
Session,StatelessSession, andSessionFactoryclass hierarchies were refactored to remove deprecated classes and to better align with the Jakarta Persistence Metamodel API. -
The SPIs in the
org.hibernate.persisterandorg.hibernate.tuplepackages have changed. Any custom classes using those SPIs will need to be reviewed and updated. -
LimitHandlerchanges introduced a newhibernate.legacy_limit_handlersetting, which is set tofalseby default, that is designed to allow you to enable the legacy Hibernate 4.3 limit handler behavior. This impacts a limited list of dialects. -
A new strategy for retrieving database tables was introduced that improves
SchemaMigratorandSchemaValidatorperformance. -
This release changes how
CLOBvalues forString,character[], andCharacter[]attributes that are annotated with@Lobare processed when using PostgreSQL81Dialect and its subclasses. -
The scope of
@TableGeneratorand@SequenceGeneratornames has changed from global to local.
For the complete list of changes implemented in Hibernate 5.2, see Hibernate ORM 5.2 Migration Guide.
Hibernate ORM 5.3 features
Hibernate ORM 5.3 adds support for the Jakarta Persistence 2.2 specification. This release contains changes to comply with this specification along with other improvements. The following is a list of some of these changes:
Changes to positional query parameter handling has resulted in the following changes:
- Removal of support for JDBC-style parameter declarations in HQL/JPQL queries.
- Jakarta Persistence positional parameters behave more like named parameters.
-
JDBC-style parameter declarations in native queries use one-based instead of zero-based parameter binding to be consistent with Jakarta Persistence. You can revert back to zero-based binding by setting the
hibernate.query.sql.jdbc_style_params_baseproperty totrue.
-
To comply with the Jakarta Persistence specification, the sequence value stored by the
@TableGeneratorstored value is that last generated value. Previously, Hibernate stored the next sequence value. You can use thehibernate.id.generator.stored_last_usedproperty to enable the legacy Hibernate behavior. Existing applications that use@TableGeneratorand migrate to Hibernate 5.3 must set thehibernate.id.generator.stored_last_used configurationproperty tofalse. -
The
getType()method in theorg.hibernate.query.QueryParameterclass was renamed togetHibernateType(). - Hibernate’s second-level cache SPI was redesigned to better meet the requirements of the various caching providers. Details can be found in HHH-11356.
- Changes for HHH-11356 also required changes in consumers, which impacts the Hibernate Statistics system.
-
Some methods were temporarily added to the
org.hibernate.Queryclass to make it easier to migrate native applications from Hibernate ORM 5.1 to 5.3 and maintain the Hibernate 5.1 pagination behavior. These methods are deprecated, and to be portable with future versions of Hibernate, applications should be updated to use the Jakarta Persistence methods. -
Support for using Infinispan as a Hibernate 2nd-level cache provider has been moved to the Infinispan project. As a result, the
hibernate-infinispanmodule has been dropped. -
The API of the
org.hibernate.tool.enhance.EnhancementTaskAnt task was changed. TheaddFileset()method was dropped in favor of thesetBase()and thesetDir()methods. Details can be found in HHH-11795. - A bug introduced in Hibernate 4.3 caused many-to-one associations in embeddable collection elements and composite IDs to be eagerly fetched, even when explicitly mapped as lazy. In Hibernate 5.3.2, this bug was fixed. As a result, these associations are fetched as specified by their mappings. Details can be found in HHH-12687.
-
Jakarta Persistence and native implementations of Hibernate event listeners were unified in this release. As a result, the
JpaIntegratorclass is obsolete. Classes that extendorg.hibernate.jpa.event.spi.JpaIntegratormust be modified to have to change these classes to implement theorg.hibernate.integrator.spi.Integratorinterface. Details can be found in HHH-11264. -
The SPIs in the
org.hibernate.persisterpackage have changed. Any custom classes using those SPIs will need to be reviewed and updated.
For the complete list of these and other changes implemented in Hibernate 5.3, see the Hibernate ORM 5.3 Migration Guide.
Exception handling changes between Hibernate 5.1 and Hibernate 5.3
In Hibernate 5.2 and 5.3, exception handling for a SessionFactory that is built using Hibernate’s native bootstrapping, wraps or converts HibernateException according to the Jakarta Persistence specification. The only exception to this behavior is when the operation is Hibernate-specific, for example Session.save() or Session.saveOrUpdate().
In Hibernate 5.3.3, the hibernate.native_exception_handling_51_compliance property was added. This property indicates whether exception handling for a SessionFactory built using Hibernate’s native bootstrapping should behave the same as native exception handling in Hibernate ORM 5.1. When set to true, HibernateException is not wrapped or converted according to the Jakarta Persistence specification. This setting is ignored for a SessionFactory built using Jakarta Persistence bootstrapping.
Compatibility transformer
JBoss EAP 7.4 includes a compatibility transformer that addresses Hibernate ORM 5.3 API methods that are no longer compatible with Hibernate ORM 5.1. The transformer is a temporary measure to allow applications built using Hibernate ORM 5.1 to exhibit the same behavior with Hibernate 5.3 in JBoss EAP 7.4. This is a temporary solution and you should replace these method calls with the recommended Jakarta Persistence method calls.
You can enable the transformer in one of the following ways:
-
You can enable the transformer globally for all applications by setting the
Hibernate51CompatibilityTransformersystem property totrue. You can use the
jboss-deployment-structure.xmlfile to enable the transformer at the application level.Copy to Clipboard Copied! Toggle word wrap Toggle overflow
The following table lists the Hibernate 5.1 methods that are transformed and the Hibernate 5.3 method it is converted to:
| Hibernate 5.1 Reference or Method | Transformed to Hibernate 5.3 Reference or Method |
|---|---|
7.9. Hibernate search changes Copy linkLink copied to clipboard!
JBoss EAP 8.1 Beta includes Hibernate search 7.2. For more information on migrating from previous versions, see the Hibernate search migration guide.
Previous versions of JBoss EAP included the following Hibernate search versions:
- JBoss EAP 6.4 included Hibernate Search 4.6
- JBoss EAP 7.0 and 7.1 included Hibernate 5.5
- JBoss EAP 7.2, 7.3 and 7.4 included Hibernate 5.10
- JBoss EAP 8.0 included Hibernate 6.2
7.10. Migrate entity beans to Jakarta Persistence Copy linkLink copied to clipboard!
Support for Enterprise Java Beans entity beans is optional in Java EE 8 and they are not supported starting with JBoss EAP 7.
In previous releases of JBoss EAP, entity beans were created in application source code by extending the javax.ejb.EntityBean class and implementing the required methods. They were then configured in the ejb-jar.xml file. A CMP entity bean was specified using an <entity> element that contained a <persistence-type> child element with a value of Container. A BMP entity bean was specified using an <entity> element that contained a <persistence-type> child element with a value of Bean.
Starting with JBoss EAP 7, you must replace any CMP and BMP entity beans in your code with Jakarta Persistence entities. Jakarta Persistence entities are created using the jakarta.persistence.* classes and are defined in the persistence.xml file.
The following is an example of a Jakarta Persistence entity class:
The following is an example of a persistence.xml file.
For working examples of Jakarta Persistence entities, see the cmt quickstart that is included with JBoss EAP 8.1-beta.
7.11. Jakarta persistence property changes Copy linkLink copied to clipboard!
This section describes the Jakarta Persistence property changes introduced in JBoss EAP 7.0 and 7.1.
Jakarta Persistence property changes introduced in JBoss EAP 7.0
A new persistence property, jboss.as.jpa.deferdetach, was added to provide compatibility with the persistence behavior in previous releases of JBoss EAP.
The jboss.as.jpa.deferdetach property controls whether the transaction-scoped persistence context used in a non-Jakarta Transactions thread detaches loaded entities after each EntityManager invocation or whether it waits until the persistence context is closed, for example, when the session bean invocation ends. The property value defaults to false, meaning entities are detached or cleared after each EntityManager invocation. This is the correct default behavior as defined in the Jakarta Persistence specification. If the property value is set to true, the entities are not detached until the persistence context is closed.
In JBoss EAP 5, persistence behaved as if the jboss.as.jpa.deferdetach property was set to true. To get this same behavior when migrating your application from JBoss EAP 5 to JBoss EAP 7, you must set the jboss.as.jpa.deferdetach property value to true in your persistence.xml as shown in the following example.
In JBoss EAP 6, persistence behaved as if the jboss.as.jpa.deferdetach property was set to false. This is the same behavior as seen in JBoss EAP 7, so no changes are necessary when you migrate your application.
Jakarta Persistence property changes introduced in JBoss EAP 7.1
In JBoss EAP 7.0, unsynchronized persistence context error checking was not as strict as it should have been in the following areas.
-
A synchronized container-managed persistence context was allowed to use an unsynchronized extended persistence context that was associated with a Jakarta Transactions. Instead, it should have thrown an
IllegalStateExceptionto prevent the unsynchronized persistence context from being used. - An unsynchronized persistence context specified in a deployment descriptor was treated as synchronized.
In addition, PersistenceProperty hints in the @PersistenceContext were mistakenly ignored in JBoss EAP 7.0.
These issues were addressed and fixed in JBoss EAP 7.1 and later. Because these updates can result in an unwanted change in application behavior, two new persistence unit properties were introduced in JBoss EAP 7.1 to provide backward compatibility and preserve the previous behavior.
| Property | Description |
|---|---|
|
| This property disables the error checking. It should only be used as a temporary measure for backward compatibility in situations where applications worked in JBoss EAP 7.0 and fail in JBoss EAP 7.1 and later. Because this property might be deprecated in a future release, it is recommended that you correct your application code as soon as you are able to do so. |

7.12. Migrate Jakarta Enterprise Beans client code Copy linkLink copied to clipboard!
This section discusses the changes in Jakarta Enterprise Beans client in JBoss EAP 7.0. It also explains how to modify your client code to use the new default remote port and connector in JBoss EAP 7.0. In addition, it describes the required JBoss EJB client changes introduced in JBoss EAP 7.1 and JBoss EAP 7.0.
Starting with JBoss EAP 7.0, enterprise entity beans are not supported. For more information, see Migrate Entity Beans to Jakarta Persistence.
7.12.1. Jakarta Enterprise Beans client changes in JBoss EAP 7 Copy linkLink copied to clipboard!
Starting with JBoss EAP 7, the default remote connector and port have been changed. For details about this change, see Update the Remote URL connector and port.
If you used the JBoss Server Migration Tool to migrate your server configuration, the old settings are preserved and you do not need to make the changes detailed here. However, if you use the new JBoss EAP 8.1-beta default configuration, you must make the following changes.
7.12.1.1. Update the default remote connection port Copy linkLink copied to clipboard!
Change the remote connection port value from 4447 to 8080 in the jboss-ejb-client.properties file. The following are examples of a jboss-ejb-client.properties file in the previous and the current release:
Example: JBoss EAP 6 jboss-ejb-client.properties file
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false remote.connections=default remote.connection.default.host=localhost remote.connection.default.port=4447 remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port=4447
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
Example: JBoss EAP 8 jboss-ejb-client.properties file
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false remote.connections=default remote.connection.default.host=localhost remote.connection.default.port=8080 remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port=8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
7.12.1.2. Update the default connector Copy linkLink copied to clipboard!
If you use the new JBoss EAP 7 configuration, the default connector has changed from remote to http-remoting. This change impacts clients using libraries from one release of JBoss EAP to connect to a server in a different release.
-
If a client application uses the Jakarta Enterprise Beans client library from JBoss EAP 6 and wants to connect to JBoss EAP 7 server, the server must be configured to expose a
remoteconnector on a port other than8080. The client must then connect using that newly configured connector. A client application that uses the Jakarta Enterprise Beans client library from JBoss EAP 7 and wants to connect to JBoss EAP 6 server must be aware that the server instance does not use the
http-remotingconnector and instead uses aremoteconnector. This is achieved by defining a new client-side connection property.Example:
remoteconnection propertyremote.connection.default.protocol=remote
remote.connection.default.protocol=remoteCopy to Clipboard Copied! Toggle word wrap Toggle overflow
7.12.2. Migrate remote naming client code Copy linkLink copied to clipboard!
If you are running with the new default JBoss EAP 7 configuration, you must modify your client code to use the new default remote port and connector.
The following is an example of how remote naming properties were specified in the client code in JBoss EAP 6.
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory java.naming.provider.url=remote://localhost:4447
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url=remote://localhost:4447
The following is an example of how to specify the remote naming properties in the client code in JBoss EAP 7.
java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory java.naming.provider.url=http-remoting://localhost:8080
java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory
java.naming.provider.url=http-remoting://localhost:8080
7.12.3. Additional JBoss EJB client changes introduced in JBoss EAP 7.1 Copy linkLink copied to clipboard!
JBoss EAP 7.0 is included with JBoss Enterprise Java Beans client 2.1.4, JBoss EAP 7.1 and later was included with JBoss Enterprise Java Beans client 4.0.x, which includes a number of changes to the API.
Starting with JBoss EAP 7, enterprise entity beans are not supported. For information about how to migrate entity beans to Jakarta Persistence, see Migrate Entity Beans to Jakarta Persistence.

7.13. Migrate clients to use the WildFly configuration file Copy linkLink copied to clipboard!
Prior to release JBoss EAP 7.1, JBoss EAP client libraries, such as Enterprise Java Beans and naming, used different configuration strategies. JBoss EAP 7.1 introduced the wildfly-config.xml file with the purpose of unifying all client configurations into one single configuration file, in a similar manner to the way the server configuration is handled.
For example, prior to JBoss EAP 7.1, you might create a new InitialContext for an Enterprise Java Beans client using a jboss-ejb-client.properties file, or by programmatically setting the properties using a Properties class.
Example: jboss-ejb-client.properties properties file
In JBoss EAP 7.1 and later, you create a wildfly-config.xml file in the META-INF/ directory of the client archive. This is the equivalent configuration using a wildfly-config.xml file.
Example: Equivalent configuration using the wildfly-config.xml file
7.14. Migrate deployment plan configurations Copy linkLink copied to clipboard!
The Java EE Application Deployment specification (JSR-88) was intended to define a standard contract to enable tools from multiple providers to configure and deploy applications on any Java EE platform product. The contract required Java EE Product Providers to implement the DeploymentManager and other javax.enterprise.deploy.spi interfaces to be accessed by the Tool Providers. In case of JBoss EAP 6, a deployment plan is identified by an XML descriptor named deployment-plan.xml that is bundled in a archive or JAR archive.
This specification saw very little adoption because most application server products provide their own more "feature rich" deployment solutions. For this reason, JSR-88 support was dropped from Java EE 7 and, in turn, from JBoss EAP 7.
If you used JSR-88 to deploy your application, you must now use another method to deploy the application. The JBoss EAP management CLI deploy command provides a standard way to deploy archives to standalone servers or to server groups in a managed domain. For more information about the management CLI, see the Management CLI Guide.
7.15. Migrate custom application valves Copy linkLink copied to clipboard!
You must manually migrate custom valves or any valves that are defined in the jboss-web.xml XML file. This includes valves created by extending the org.apache.catalina.valves.ValveBase class and configured in the <valve> element of the jboss-web.xml descriptor file.
Migrate Valves Configured in Deployments
In JBoss EAP 6, you could define custom valves at the application level by configuring them in the jboss-web.xml web application descriptor file. Since JBoss EAP 7, it is possible to do this with Undertow handlers as well.
The following is an example of a valve configured in the jboss-web.xml file in JBoss EAP 6.
For more information about how to create and configure custom handlers in JBoss EAP, see Creating Custom Handlers in the JBoss EAP 7.4 Development Guide.
Migrate Custom Authenticator Valves
For information about how to migrate authenticator valves, see Migrate authenticator valves.
7.16. Security application changes Copy linkLink copied to clipboard!
The replacement of JBoss Web with Undertow requires changes to security configuration since JBoss EAP 7. Starting with JBoss EAP 8.0, you must use Elytron as the legacy security since PicketBox is no longer available.
7.16.1. Migrate authenticator valves Copy linkLink copied to clipboard!
If you created a custom authenticator valve that extended AuthenticatorBase in JBoss EAP 6.4, you must manually replace it with a custom HTTP authentication implementation in JBoss EAP 7. The HTTP authentication mechanism is created in the elytron subsystem and then registered with the undertow subsystem. For information about how to implement a custom HTTP authentication mechanism, see Developing a Custom HTTP Mechanism in the JBoss EAP 7.4 Development Guide.
7.16.2. PicketLink removal Copy linkLink copied to clipboard!
PicketLink has been removed from JBoss EAP 8.0.
PicketLink SP
Use Keycloak SAML adapter instead of the PicketLink service provider.
To migrate from PicketLink by configuring the Keycloak SAML adapter, perform the following tasks:
Install Keycloak SAML client to JBoss EAP 8.1 Beta. For more information, see
- link:https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/8.1 Beta/html/red_hat_jboss_enterprise_application_platform_installation_methods/#assembly_installing-jboss-eap-8-using-the-cli-installer-method_default[Installing JBoss EAP 8.1 Beta using the jboss-eap-installation-manager]
- Keycloak SAML adapter feature pack for securing applications using SAML
- Configure a Keycloak SAML instead of PicketLink IdP if needed. To secure the SP application using Keycloak SAML, you need to create a SAML client. For more information on creating a Keycloak SAML client, see Creating an OpenID Connect client in the Server Administration Guide.
- Update the applications to use the Keycloak SAML adapter. For more information on updating the applications, see Securing web applications using SAML.
PicketLink IDP
PicketLink IDP is not available since JBoss EAP 8.1 Beta and you can configure Red Hat build of Keycloak instead. For more information, see Configuring Red Hat build of Keycloak.
PicketLink STS
In previous releases, you could configure PicketLink STS as an alternative to the Apache CXF Security Token Service implementation. PicketLink STS configuration involved a legacy security domain. Any references to legacy security domains and PicketLink in the STS application needs to be removed, so you must configure Apache CXF STS instead.
For more information on how to configure Apache CXF STS, see Security Token Service (STS) in the JBoss EAP 7.4 Developing Web Services Applications.
7.16.3. Vault removal Copy linkLink copied to clipboard!
Vaults has been removed from JBoss EAP 8.1-beta. If your applications use legacy vault expressions, you must migrate and use Elytron encrypted expressions.
Check for instances of ${VAULT:: in your deployment files, which could be in annotations or deployment descriptors, and replace them with the corresponding encrypted expressions.
7.16.4. OIDC client migration Copy linkLink copied to clipboard!
The Keycloak OIDC client adapter is not supported in JBoss EAP 8.1-beta and is replaced by the native Elytron OIDC client, providing similar functionality and configuration.
To migrate from the Keycloak OIDC client adapter to the native Elytron OIDC client, follow these steps:
-
Check for
<auth-method>KEYCLOAK</auth-method>in theweb.xmlfile of the application and replace it with<auth-method>OIDC</auth-method>in theweb.xmlfile of the deployment. -
Check for the presence of
WEB-INF/keycloak.jsonand rename it toWEB-INF/oidc.json.
7.16.5. Custom login modules migration Copy linkLink copied to clipboard!
In JBoss EAP 8.0, the legacy security subsystem has been removed. To continue using your custom login modules with the elytron subsystem, use the new Java Authentication and Authorization Service (JAAS) security realm and jaas-realm.
7.16.6. Other security application changes Copy linkLink copied to clipboard!
There are a few noticeable differences between JBoss EAP 7.2 or higher and earlier versions:
-
The
NegotiationAuthenticatorvalve is not required in thejboss-web.xml, but there still must be<security-constraint>and<login-config>elements defined in theweb.xml. These are used to decide which resources are secured. -
The
auth-methodelement in the<login-config>element is now a comma-separated list. The exact valueSPNEGOmust be there and should appear first in that list. In cases whereFORMauthentication is desired as a fallback, the exact value would beSPNEGO,FORM. -
The
jboss-deployment-structure.xmlfile is not required.
7.17. JBoss Logging Changes Copy linkLink copied to clipboard!
Starting with JBoss EAP 7, if your application uses JBoss Logging, be aware that the annotations in the org.jboss.logging package are deprecated. They have been moved to the org.jboss.logging.annotations package, so you must update your source code to import the new package.
The annotations have also moved to a separate Maven groupId:artifactId:version (GAV) ID so you need to add a new project dependency for org.jboss.logging:jboss-logging-annotations in your project pom.xml file.
Only the logging annotations have moved. The org.jboss.logging.BasicLogger and org.jboss.logging.Logger still exist in the org.jboss.logging package.
The following table lists the deprecated annotation classes and corresponding replacements.
| Deprecated Class | Replacement Class |
|---|---|
| org.jboss.logging.Cause | org.jboss.logging.annotations.Cause |
| org.jboss.logging.Field | org.jboss.logging.annotations.Field |
| org.jboss.logging.FormatWith | org.jboss.logging.annotations.FormatWith |
| org.jboss.logging.LoggingClass | org.jboss.logging.annotations.LoggingClass |
| org.jboss.logging.LogMessage | org.jboss.logging.annotations.LogMessage |
| org.jboss.logging.Message | org.jboss.logging.annotations.Message |
| org.jboss.logging.MessageBundle | org.jboss.logging.annotations.MessageBundle |
| org.jboss.logging.MessageLogger | org.jboss.logging.annotations.MessageLogger |
| org.jboss.logging.Param | org.jboss.logging.annotations.Param |
| org.jboss.logging.Property | org.jboss.logging.annotations.Property |
7.18. Jakarta Faces code changes Copy linkLink copied to clipboard!
This section describes the impact of the Jakarta Faces code changes in migrating your application to JBoss EAP.
Dropped support for Jakarta Server Faces prior to 4.0
Jakarta Server Faces is the new name for JavaServer Faces.
With JBoss EAP 6.4, you could continue to use Jakarta Server Faces 1.2 with your application deployment by creating a jboss-deployment-structure.xml file. JBoss EAP 7.4 includes Jakarta Server Faces 2.3 and no longer supports the Jakarta Server Faces 1.2 API. If your application uses Jakarta Server Faces 1.2, you must rewrite it to use Jakarta Server Faces 2.3.
JBoss EAP 8.0 no longer supports any version of JSF prior to 4.0.
7.19. Integrate MyFaces for alternative faces Copy linkLink copied to clipboard!
You can simplify the installation of an alternative Jakarta Faces implementation, MyFaces, as an alternative to the default Mojarra Jakarta Faces implementation within the JBoss EAP by introducing the Galleon feature pack, eap-myfaces-feature-pack. You can use this feature pack to provision a different Jakarta Faces implementation within JBoss EAP.
You can use the eap-myfaces-feature-pack to select the MyFaces version by using the MYFACES_VERSION environment variable. This feature pack introduces a single layer named MyFaces, providing the option to install and select MyFaces as an alternative. For more information, see How to configure the Multi-JSF feature in EAP 8.
Compatibility with JBoss EAP 8.1 Beta is limited to versions 4.x and above.
7.20. Module class loading changes Copy linkLink copied to clipboard!
In JBoss EAP 7, the class loading behavior has changed in cases where multiple modules contain the same classes or packages.
Assume there are two modules, MODULE_A and MODULE_B, that depend upon each other and contain some of the same packages. In JBoss EAP 6, the classes or packages that were loaded from the dependencies took precedence over those specified in the resource-root of the module.xml file. This meant MODULE_A saw the packages for MODULE_B and MODULE_B saw the packages for MODULE_A. This behavior was confusing and could cause conflicts. This behavior has changed in JBoss EAP 7. Now the classes or packages specified by the resource-root in the module.xml file take precedence over those specified by the dependency. This means MODULE_A sees the packages for MODULE_A and MODULE_B sees the packages for MODULE_B. This prevents conflicts and provides a more appropriate behavior.
If you have defined custom modules that include resource-root libraries or packages that contain classes that are duplicated in their module dependencies, you might see ClassCastException, LinkageError, class loading errors, or other changes in behavior when you migrate to JBoss EAP 7. To resolve these issues, you must configure your module.xml file to ensure only one version of a class is used. This can be accomplished by using either of the following approaches.
-
You can avoid specifying a
resource-rootthat duplicates classes in the module dependency. You can use the
includeandexcludesub-elements of theimportsandexportselements to control class loading in themodule.xmlfile. The following is an export element that excludes classes is in the specified package.<exports> <exclude path="com/mycompany/duplicateclassespath/"/> </exports>
<exports> <exclude path="com/mycompany/duplicateclassespath/"/> </exports>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
If you prefer to preserve your existing behavior, you must filter the dependency packages from the dependent resource-root in the module.xml file using the filter element. This allows you to retain the existing behavior without the odd looping that you would see under JBoss EAP 6. The following is an example of a root-resource that filters classes in a specified package.
<resource-root path="mycompany.jar">
<filter>
<exclude path="com/mycompany/duplicateclassespath"/>
</filter>
</resource-root>
<resource-root path="mycompany.jar">
<filter>
<exclude path="com/mycompany/duplicateclassespath"/>
</filter>
</resource-root>

7.21. Application Clustering Changes Copy linkLink copied to clipboard!
This section provides an overview of the clustering changes required for migrating your application from JBoss EAP 6 to JBoss EAP 8. In addition, this section describes how clustering changes might impact the migration of your applications to JBoss EAP 8.1-beta.
7.21.1. Overview of new clustering features Copy linkLink copied to clipboard!
The following list describes some of the new clustering features to be aware of when migrating your application from JBoss EAP 6 to JBoss EAP 8.1 Beta.
- JBoss EAP 7 introduces a new public API for building singleton services that significantly simplifies the process. For information on singleton services, see HA Singleton Service in the JBoss EAP 7.4 Development Guide
- A singleton deployment can be configured to deploy and start on only a single node in the cluster at a time. For more information, see HA Singleton Deployments in the JBoss EAP 7.4 Development Guide.
- You can now define clustered singleton MDBs. For more information, see Clustered Singleton MDBs in the JBoss EAP 7.4 Developing Jakarta Enterprise Beans Applications.
- JBoss EAP 8.1 Beta includes the Undertow mod_cluster implementation. This offers a pure Java load balancing solution that does not require an httpd web server. For more information, see Configuring JBoss EAP as a Front-end Load Balancer in the Configuration Guide.
7.21.2. Web Session Clustering Changes Copy linkLink copied to clipboard!
JBoss EAP 7 introduces a new web session clustering implementation. It replaces the previous implementation, which was tightly coupled to the legacy JBoss Web subsystem source code.
The new web session clustering implementation impacts how the application is configured in the jboss-web.xml JBoss EAP proprietary web application XML descriptor file. The following are the only clustering configuration elements that remain in this file.
The distributable-web subsystem deprecates the <replication-config> element of jboss-web.xml. It enhances the usage of <replication-config> by generating an ad hoc distributable web session profile.
You can override the default distributable session management behavior by referencing a session management profile by name or by providing a deployment-specific session management configuration. For more information, see Overriding the default distributable session management behavior.
The following table describes how to achieve similar behavior for elements in the jboss-web.xml file that are now obsolete.
| Configuration Element | Description of Change |
|---|---|
| <max-active-sessions/> |
Previously, the session creation would fail if it caused the number of active sessions to exceed the value specified by
In the new implementation, |
| <passivation-config/> | Starting with JBoss EAP 7, this configuration element and its sub-elements are no longer used. |
| <use-session-passivation/> | Previously, passivation was enabled using this attribute.
In the new implementation, passivation is enabled by specifying a non-negative value for |
| <passivation-min-idle-time/> | Previously, sessions needed to be active for a minimum amount of time before becoming a candidate for passivation. This could cause session creation to fail, even when passivation was enabled. The new implementation does not support this logic and thus avoids this Denial of Service (DoS) vulnerability. |
| <passivation-max-idle-time/> | Previously, a session would be passivated after it was idle for a specific amount of time.
The new implementation only supports lazy passivation. It does not support eager passivation. Sessions are only passivated when necessary to comply with |
| <replication-config/> |
The |
| <replication-trigger/> | Previously, this element was used to determine when session replication was triggered. The new implementation replaces this configuration option with a single, robust strategy. For more information, see Immutable Session Attributes in the JBoss EAP 8.0 Development Guide. |
| <use-jk/> |
Previously, the
In the new implementation, the |
| <max-unreplicated-interval/> | Previously, this configuration option was intended as an optimization to prevent the replication of a session’s timestamp if no session attribute was changed. While this sounds nice, in practice it does not prevent any RPCs, since session access requires cache transaction RPCs regardless of whether any session attributes changed. In the new implementation, the timestamp of a session is replicated on every request. This prevents stale session metadata following a failover. |
| <snapshot-mode/> |
Previously, one could configure |
| <snapshot-interval/> |
This was only relevant for |
| <session-notification-policy/> | Previously, the value specified by this attribute defined a policy for triggering session events. In the new implementation, this behavior is specification-driven and not configurable. |
This new implementation also supports write-through cache stores as well as passivation-only cache stores. Typically, a write-through cache store is used in conjunction with an invalidation cache. The web session clustering implementation in JBoss EAP 6 did not operate correctly when used with an invalidation cache.
7.21.3. Overriding the default distributable session management behavior Copy linkLink copied to clipboard!
You can override the default distributable session management behavior in one of the following ways:
- Referencing a session management profile by name
- Providing a deployment-specific session management configuration
Referencing an existing session management profile
-
To use an existing distributed session management profile, include a
distributable-web.xmldeployment descriptor located in the application’s/WEB-INFdirectory. For example:
/WEB-INF/distributable-web.xml
<?xml version="1.0" encoding="UTF-8"?>
<distributable-web xmlns="urn:jboss:distributable-web:1.0">
<session-management name="foo"/>
</distributable-web>
<?xml version="1.0" encoding="UTF-8"?>
<distributable-web xmlns="urn:jboss:distributable-web:1.0">
<session-management name="foo"/>
</distributable-web>
-
Alternatively, define the target distributed session management profile within an existing
jboss-all.xmldeployment descriptor:
/META-INF/jboss-all.xml
Using a Deployment-specific Session Management Profile
If only a single web application uses the custom session management configuration, you can define the configuration within the deployment descriptor itself. Ad hoc configuration looks identical to the configuration used by the distributable-web subsystem.
- Define the custom session management configuration within the deployment descriptor. For example:
/WEB-INF/distributable-web.xml
-
Alternatively, define the session management configuration within an existing
jboss-all.xmldeployment descriptor:
/META-INF/jboss-all.xml
7.21.4. Stateful session EJB clustering changes Copy linkLink copied to clipboard!
In JBoss EAP 6, you were required to enabled the clustering behavior for stateful session beans (SFSBs) in one of the following ways:
You could add the
org.jboss.ejb3.annotation.Clusteredannotation in the session bean.Copy to Clipboard Copied! Toggle word wrap Toggle overflow You could add the
<clustered>element to thejboss-ejb3.xmlfile.<c:clustering> <ejb-name>DDBasedClusteredSFSB</ejb-name> <c:clustered>true</c:clustered> </c:clustering>
<c:clustering> <ejb-name>DDBasedClusteredSFSB</ejb-name> <c:clustered>true</c:clustered> </c:clustering>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
Starting with JBoss EAP 7, you no longer need to enable the clustering behavior. By default, if the server is started using an HA profile, the state of SFSBs will be replicated automatically. You can disable this default behavior in one of the following ways:
-
You can disable the default behavior for a single stateful session bean by using
@Stateful(passivationCapable=false), which is new to the Enterprise Java Beans 3.2 specification. -
You can disable this behavior globally in the configuration of the
ejb3subsystem in the server configuration.
If the @Clustered annotation is not removed from the application, it is simply ignored and does not affect the deployment of the application.
7.21.5. Clustering services changes Copy linkLink copied to clipboard!
In JBoss EAP 6, the APIs for clustering services were in private modules and were not supported.
JBoss EAP 7 introduces a public clustering services API for use by applications. The new services are designed to be lightweight, easily injectable, and require no external dependencies.
-
The new
org.wildfly.clustering.group.Groupinterface provides access to the current cluster status and allows listening for cluster membership changes. -
The new
org.wildfly.clustering.dispatcher.CommandDispatcherinterface allows running code in the cluster, on all or a selected subset of nodes.
These services replace similar APIs that were available in previous releases, namely HAPartition from JBoss EAP 5 and GroupCommunicationService, GroupMembershipNotifier, and GroupRpcDispatcher in JBoss EAP 6.
For more information, see Public API for Clustering Services in the JBoss EAP 7.4 Development Guide.
7.21.6. Migrate Clustering HA Singleton Copy linkLink copied to clipboard!
In JBoss EAP 6, there was no public API available for the cluster-wide HA singleton service. If you used the private org.jboss.as.clustering.singleton.* classes, you must change your code to use the new public org.wildfly.clustering.singleton.* packages when you migrate your application to JBoss EAP 8.
For more information about HA singleton services, see HA Singleton Service in the JBoss EAP 7.4 Development Guide. For information about HA singleton deployments, see HA Singleton Deployments in the JBoss EAP 7.4 Development Guide.
7.22. ContextService customization by using context types Copy linkLink copied to clipboard!
As part of Jakarta EE Concurrency 3.0, you can customize the ContextService property by using context types. The Transaction context is one such type. The Transaction context replaces the use of the use-transaction-setup-provider resource-definition attribute. When the use-transaction-setup-provider attribute is set to true, the transaction context is cleared and when this attribute is set to false, the transaction context is unchanged.
Red Hat no longer supports vendor-specific configurations and therefore, such resource-definition attributes have been deprecated. In JBoss EAP 7, the default configurations defined the use-transaction-setup-provider attribute as false, which means that the transaction context was unchanged when a contextual task was run on a thread. By default, in JBoss EAP 8, the default ContextService property is aligned with the Jakarta EE Concurrency 3.0 specification, and clears the transaction context before a contextual task is executed.
To use a different ContextService, you must define it on the deployment by using the ContextServiceDefinition annotation or by specifying it in XML.
7.23. Removal of deprecated InitialContext class Copy linkLink copied to clipboard!
The org.jboss.naming.remote.client.InitialContextFactory class is removed in JBoss EAP 8. In JBoss EAP 7, the org.jboss.naming.remote.client.InitialContextFactory class had been deprecated and replaced with the org.wildfly.naming.client.WildFlyInitialContextFactory class. You must migrate your source code or configuration files to reflect this change.
Naming configuration changes:
-
If a user application is using system or environment properties, then
java.naming.factory.initialproperty must be migrated fromjava.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactorytojava.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory. -
If a user application is using WSDL contracts that contain
<soapjms:jndiInitialContextFactory>, then their values must be migrated from<soapjms:jndiInitialContextFactory>org.jboss.naming.remote.client.InitialContextFactory<soapjms:jndiInitialContextFactory>to<soapjms:jndiInitialContextFactory>org.wildfly.naming.client.WildFlyInitialContextFactory<soapjms:jndiInitialContextFactory>. -
If a user application is using Java code to configure remote naming, then it must be updated from
Properties env = new Properties();env.put(Context.INITIAL_CONTEXT_FACTORY, org.jboss.naming.remote.client.InitialContextFactory.class.getName());toenv.put(Context.INITIAL_CONTEXT_FACTORY, org.wildfly.naming.client.WildFlyInitialContextFactory.class.getName());.
The methods listed below, from the org.wildfly.naming.client.ProviderEnvironment class, have been deprecated in JBoss EAP 7 and are now removed in JBoss EAP 8 as part of Red Hat’s commitment to replacing problematic language in our code, documentation, and web properties. For more details, see our CTO Chris Wright’s message.
Any code containing a removed method must be refactored using the corresponding replacement:
-
getBlackList()replaced bygetBlockList() -
updateBlacklist(URI)replaced byupdateBlockList(URI) -
dropFromBlacklist(URI)replaced bydropFromBlocklist(URI)
7.24. Resource Adapters Copy linkLink copied to clipboard!
A Jakarta Connectors Resource Adapter lets your applications communicate with any messaging provider. It configures how Jakarta EE components such as MDBs and other Jakarta Enterprise Beans, and even Servlets, can send or receive messages.
7.24.1. Deploying the IBM MQ Resource Adapter Copy linkLink copied to clipboard!
IBM MQ is the Messaging Oriented Middleware (MOM) product offering from IBM that allows applications on distributed systems to communicate with each other. This is accomplished through the use of messages and message queues. IBM MQ is responsible for delivering messages to the message queues and for transferring data to other queue managers using message channels. For more information about IBM MQ, see IBM MQ on the IBM products website.
Summary
IBM MQ can be configured as an external Java Message Service provider for JBoss EAP 8.1 Beta. This section covers the steps to deploy and configure the IBM MQ resource adapter in JBoss EAP. This deployment and configuration can be accomplished by using the management CLI tool or the web-based management console. See JBoss EAP supported configurations for the most current information about the supported configurations of IBM MQ.
You must restart your system after configuring your IBM MQ resource adapter for the configuration changes to take effect.
JBoss EAP 8.0 is a Jakarta EE 10 implementation, so the packages used for all EE APIs have changed from javax to jakarta, which requires a Jakarta EE 10 compliant resource adapter. If you were using the IBM MQ Resource adapter in JBoss EAP 7.x or earlier, you must use wmq.jakarta.jmsra.rar, the IBM MQ Resource Adapter that uses this jakarta namespace.
-
Remove and undeploy the previous resource adapter configuration for
wmq.jmsra.rarand usewmq.jakarta.jmsra.rar -
Deploy
wmq.jakarta.jmsra.rarand configure as per the steps provided in this section.
Prerequisites
Before you get started, you must verify the version of the IBM MQ resource adapter and understand its configuration properties.
-
The IBM MQ resource adapter is supplied as a Resource Archive (RAR) file called
wmq.jakarta.jmsra.rar. You can obtain thewmq.jakarta.jmsra.rarfile from/opt/mqm/java/lib/jca/wmq.jakarta.jmsra.rar. See JBoss EAP supported configurations for information about the specific versions that are supported for each release of JBoss EAP. You must know the following IBM MQ configuration values. Refer to the IBM MQ product documentation for details about these values.
- MQ_QUEUE_MANAGER: The name of the IBM MQ queue manager
- MQ_HOST_NAME: The host name used to connect to the IBM MQ queue manager
- MQ_CHANNEL_NAME: The server channel used to connect to the IBM MQ queue manager
- MQ_QUEUE_NAME: The name of the destination queue
- MQ_TOPIC_NAME: The name of the destination topic
- MQ_PORT: The port used to connect to the IBM MQ queue manager
- MQ_CLIENT: The transport type
For outbound connections, you must also be familiar with the following configuration value:
- MQ_CONNECTIONFACTORY_NAME: The name of the connection factory instance that will provide the connection to the remote system
Procedure
The following are default configurations provided by IBM and are subject to change. Refer to the IBM MQ documentation for more information.
-
First, deploy the resource adapter manually by copying the
wmq.jakarta.jmsra.rarfile to theEAP_HOME/standalone/deployments/directory. Next, use the management CLI to add the resource adapter and configure it.

7.24.2. Removal of Apache Log4j version 1 APIs Copy linkLink copied to clipboard!
Starting with JBoss EAP 8, support for Apache Log4j version 1 APIs has been stopped. Any application that is not packaging log4j.jar and log4j configuration must be updated.
Impact:
Log messages will no longer be routed based on the logging subsystem. If an application is not packaging log4j.jar and any of the following statements are true, then migration changes are required:
-
If you use
log4jin your deployment and do not include alog4jconfiguration file, then you must either migrate to a new logging facade or add alog4jconfiguration to your deployment. -
If you use a
log4j.xml,log4j.properties, orjboss-log4j.xmlfile in your deployment and are not packaging thelog4j.jarin your application. If it is ajboss-log4j.xmlfile, then you must rename the file tolog4j.xml. -
If you use
log4jv1 appenders in the JBoss EAP Logging subsystem in a custom-handler, it will be no longer supported. -
If an application classes import classes such as
org.apache.log4j.Logger. -
If the application includes a
jboss-deployment-structure.xmlor hasDependencies:specified in theMANIFEST.MFdeclaring a module dependency onorg.jboss.log4j.logmanager, these dependencies will need to be removed.
Migration:
-
Update the application classes to use Apache
Log4jv2classes or use one of the other Logging APIs provided by JBoss EAP 8. -
Change the
org.apache.log4j.Logger (log4j v1)class toorg.apache.logging.log4j.Logger (log4j v2). If an application packages
log4j.properties,log4j.xml, orjboss-log4j.xml, you must::- Configure the logging in the JBoss EAP configuration.
-
Configure
logging.propertiesin an application as thelog4jv2configuration files are not supported in an application.
OR
-
Package the Apache
Log4jversion 1 JAR in the application instead of depending on JBoss EAP 8 for the Logging APIs. You can also exclude the JBoss Logging APIs from the application by thejboss-deployment-structure.xml exclude-subsystemson the logging subsystem.
Additional Details:
- Disabling implicit logging dependencies for a specific deployment
-
In an application’s
jboss-deployment-structure.xml, configureexclude-subsystemsto exclude the logging subsystem such as:
-
In an application’s
-
If the application is an EAR file and has a sub-deployment named
example.war, thejboss-deployment-structure.xmlfile is located in the EAR file location/ META-INF/jboss-deployment-structure.xmland the logging subsystem will be excluded by declaring it in the sub-deployment such as:
- Disabling implicit logging dependencies for all deployments
To make logging APIs unavailable to deployments by default, set
add-logging-api-dependenciestofalseby using the following CLI command:/subsystem=logging:write-attribute(name="add-logging-api-dependencies", value="false")
/subsystem=logging:write-attribute(name="add-logging-api-dependencies", value="false")Copy to Clipboard Copied! Toggle word wrap Toggle overflow To set the JBoss Module and Logging API as a dependency, modify the
jboss-deployment-structure.xmlorMANIFEST.MFconfiguration files:
<subsystem xmlns="urn:jboss:domain:logging:8.0">
<add-logging-api-dependencies value="false"/>
...
</subsystem>
<subsystem xmlns="urn:jboss:domain:logging:8.0">
<add-logging-api-dependencies value="false"/>
...
</subsystem>
If an application packages Apache Log4j v1 JARs and log4j configuration in an application: * Application logging is no longer managed by EAP, it is application managed. * An application should not attempt to write to the server.log as unexpected results can occur because logging frameworks are expected to be writing to specific log files.
For more information, see Apache Log4j version 1 is no longer provided in JBoss EAP 8.
7.25. OpenShift application updates for javax.api module deprecation Copy linkLink copied to clipboard!
OpenShift applications that depend on the deprecated javax.api module and use the jaxrs-server, -jpa, and jpa-distributed layers must be updated. These applications must directly depend on the required underlying modules, such as java.se, java.xml, java.xml.crypto, and jdk.xml.dom. For more information, see javax.api module deprecated in JBoss EAP 8.0.
