Chapter 3. Developing JAX-WS Web Services

When developing a web service endpoint on the server side, you have the option of starting from Java code, known as bottom-up development, or from the WSDL that defines your service, known as top-down development. If this is a new service, meaning that there is no existing contract, then the bottom-up approach is the fastest route; you only need to add a few annotations to your classes to get a service up and running. However, if you are developing a service with a contract already defined, it is far simpler to use the top-down approach, since the tool can generate the annotated code for you.

Bottom-up use cases:

Top-down use cases:

Bottom-Up Strategy Using wsprovide

The bottom-up strategy involves developing the Java code for your service, and then annotating it using JAX-WS annotations. These annotations can be used to customize the contract that is generated for your service. For example, you can change the operation name to map to anything you like. However, all of the annotations have sensible defaults, so only the @WebService annotation is required.

This can be as simple as creating a single class:

package echo;

@javax.jws.WebService
public class Echo {

   public String echo(String input) {
      return input;
   }
}

A deployment can be built using this class, and it is the only Java code needed to deploy on JBossWS. The WSDL, and all other Java artifacts called wrapper classes will be generated for you at deploy time.

The primary purpose of the wsprovide tool is to generate portable JAX-WS artifacts. Additionally, it can be used to provide the WSDL file for your service. This can be obtained by invoking wsprovide using the -w option:

$ javac -d . Echo.java
$ EAP_HOME/bin/wsprovide.sh --classpath=. -w echo.Echo

Inspecting the WSDL reveals a service named EchoService:

<wsdl:service name="EchoService">
  <wsdl:port name="EchoPort" binding="tns:EchoServiceSoapBinding">
    <soap:address location="http://localhost:9090/EchoPort"/>
  </wsdl:port>
</wsdl:service>

As expected, this service defines an operation, echo:

<wsdl:portType name="Echo">
  <wsdl:operation name="echo">
    <wsdl:input name="echo" message="tns:echo">
    </wsdl:input>
    <wsdl:output name="echoResponse" message="tns:echoResponse">
    </wsdl:output>
  </wsdl:operation>
</wsdl:portType>

When deploying you do not need to run this tool. You only need it for generating portable artifacts or the abstract contract for your service.

A POJO endpoint for the deployment can be created in a simple web.xml file:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
  version="2.4">

  <servlet>
    <servlet-name>Echo</servlet-name>
    <servlet-class>echo.Echo</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>Echo</servlet-name>
    <url-pattern>/Echo</url-pattern>
  </servlet-mapping>
</web-app>

The web.xml and the single Java class can now be used to create a WAR:

$ mkdir -p WEB-INF/classes
$ cp -rp echo WEB-INF/classes/
$ cp web.xml WEB-INF
$ jar cvf echo.war WEB-INF
added manifest
adding: WEB-INF/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/echo/(in = 0) (out= 0)(stored 0%)
adding: WEB-INF/classes/echo/Echo.class(in = 340) (out= 247)(deflated 27%)
adding: WEB-INF/web.xml(in = 576) (out= 271)(deflated 52%)

The WAR can then be deployed to JBoss EAP. This will internally invoke wsprovide, which will generate the WSDL. If the deployment was successful, and you are using the default settings, it should be available in the management console.

Top-Down Strategy Using wsconsume

The top-down development strategy begins with the abstract contract for the service, which includes the WSDL file and zero or more schema files. The wsconsume tool is then used to consume this contract, and produce annotated Java classes, and optionally sources, that define it.

Using the WSDL file from the bottom-up example, a new Java implementation that adheres to this service can be generated. The -k option is passed to wsconsume to preserve the Java source files that are generated, instead of providing just Java classes:

$ EAP_HOME/bin/wsconsume.sh -k EchoService.wsdl

The following table shows the purpose of each generated file:

Examining the service endpoint interface reveals annotations that are more explicit than in the class written by hand in the bottom-up example, however, these evaluate to the same contract.

@WebService(targetNamespace = "http://echo/", name = "Echo")
@XmlSeeAlso({ObjectFactory.class})
public interface Echo {

    @WebMethod
    @RequestWrapper(localName = "echo", targetNamespace = "http://echo/", className = "echo.Echo_Type")
    @ResponseWrapper(localName = "echoResponse", targetNamespace = "http://echo/", className = "echo.EchoResponse")
    @WebResult(name = "return", targetNamespace = "")
    public java.lang.String echo(
        @WebParam(name = "arg0", targetNamespace = "")
        java.lang.String arg0
    );
}

The only missing piece, other than for packaging, is the implementation class, which can now be written using the above interface.

package echo;

@javax.jws.WebService(endpointInterface="echo.Echo")
public class EchoImpl implements Echo {
   public String echo(String arg0) {
      return arg0;
   }
}

Before going in to detail on the client side, it is important to understand the decoupling concept that is central to web services. Web services are not the best fit for internal RPC, even though they can be used in this way. There are much better technologies for this, such as CORBA and RMI. Web services were designed specifically for interoperable coarse-grained correspondence. There is no expectation or guarantee that any party participating in a web service interaction will be at any particular location, running on any particular operating system, or written in any particular programming language. So because of this, it is important to clearly separate client and server implementations. The only thing they should have in common is the abstract contract definition. If, for whatever reason, your software does not adhere to this principal, then you should not be using web services. For the above reasons, the recommended methodology for developing a client is to follow the top-down approach, even if the client is running on the same server.

Top-Down Strategy Using wsconsume

This section repeats the process of the server-side top-down section, however, it uses a deployed WSDL. This is to retrieve the correct value for soap:address, shown below, which is computed at deploy time. This value can be edited manually in the WSDL if necessary, but you must take care to provide the correct path.

<wsdl:service name="EchoService">
  <wsdl:port name="EchoPort" binding="tns:EchoServiceSoapBinding">
    <soap:address location="http://localhost.localdomain:8080/echo/Echo"/>
  </wsdl:port>
</wsdl:service>

Use wsconsume to generate Java classes for the deployed WSDL.

$ EAP_HOME/bin/wsconsume.sh -k http://localhost:8080/echo/Echo?wsdl

Notice how the EchoService.java class stores the location from which the WSDL was obtained.

@WebServiceClient(name = "EchoService",
                  wsdlLocation = "http://localhost:8080/echo/Echo?wsdl",
                  targetNamespace = "http://echo/")
public class EchoService extends Service {

    public final static URL WSDL_LOCATION;

    public final static QName SERVICE = new QName("http://echo/", "EchoService");
    public final static QName EchoPort = new QName("http://echo/", "EchoPort");

    ...

    @WebEndpoint(name = "EchoPort")
    public Echo getEchoPort() {
        return super.getPort(EchoPort, Echo.class);
    }

    @WebEndpoint(name = "EchoPort")
    public Echo getEchoPort(WebServiceFeature... features) {
        return super.getPort(EchoPort, Echo.class, features);
    }
}

As you can see, this generated class extends the main client entry point in JAX-WS, javax.xml.ws.Service. While you can use Service directly, this is far simpler since it provides the configuration information for you. Note the getEchoPort() method, which returns an instance of our service endpoint interface. Any web service operation can then be called by just invoking a method on the returned interface.

Write and compile the client:

import echo.*;

public class EchoClient {

   public static void main(String args[]) {

      if (args.length != 1) {
          System.err.println("usage: EchoClient <message>");
          System.exit(1);
      }

      EchoService service = new EchoService();
      Echo echo = service.getEchoPort();
      System.out.println("Server said: " + echo.echo(args0));
   }
}

You can change the endpoint address of your operation at runtime, by setting the ENDPOINT_ADDRESS_PROPERTY as shown below:

EchoService service = new EchoService();
Echo echo = service.getEchoPort();

/* Set NEW Endpoint Location */
String endpointURL = "http://NEW_ENDPOINT_URL";
BindingProvider bp = (BindingProvider)echo;
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpointURL);

System.out.println("Server said: " + echo.echo(args0));

A JAX-WS web service endpoint is the server component of a web service. Clients and other web services communicate with it over the HTTP protocol using an XML language called Simple Object Access Protocol (SOAP). The endpoint itself is deployed into the JBoss EAP container.

WSDL descriptors can be created in one of the following two ways:

An endpoint implementation bean is annotated with JAX-WS annotations and deployed to the server. The server automatically generates and publishes the abstract contract in WSDL format for client consumption. All marshalling and unmarshalling is delegated to the Java Architecture for XML Binding (JAXB) service.

The endpoint itself might be a Plain Old Java Object (POJO) or a Java EE web application. You can also expose endpoints using an EJB3 stateless session bean. It is packaged into a web archive (WAR) file. The specification for packaging the endpoint, called a Java Service Endpoint (JSE) is defined in JSR-181.

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class JSEBean {
    @WebMethod
    public String echo(String input) {
        ...
    }
}

<web-app ...>
  <servlet>
    <servlet-name>TestService</servlet-name>
    <servlet-class>org.jboss.quickstarts.ws.jaxws.samples.jsr181pojo.JSEBean01</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>TestService</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>
</web-app>

The following EJB3 stateless session bean exposes the same method on the remote interface as well as an endpoint operation.

@Stateless
@Remote(EJB3RemoteInterface.class)

@WebService

@SOAPBinding(style = SOAPBinding.Style.RPC)
public class EJB3Bean implements EJB3RemoteInterface {
    @WebMethod
    public String echo(String input) {
        ...
    }
}

Service Endpoint Interface

JAX-WS services typically implement a Java service endpoint interface (SEI), which might be mapped from a WSDL port type, either directly or using annotations. This SEI provides a high-level abstraction that hides the details between Java objects and their XML representations.

Endpoint Provider Interface

In some cases, JAX-WS services need the ability to operate at the XML message level. The endpoint Provider interface provides this functionality to the web services that implement it.

Consuming and Accessing the Endpoint

After you deploy your web service, you can consume the WSDL to create the component stubs which will be the basis for your application. Your application can then access the endpoint to do its work.

A JAX-WS service endpoint is a server-side component that responds to requests from JAX-WS clients and publishes the WSDL definition for itself.

See the following quickstarts that ship with JBoss EAP for working examples of how to develop JAX-WS endpoint applications.

Development Requirements

A web service must fulfill the requirements of the JAX-WS API and the JSR 181: Web Services Metadata for the Java Platform specification. A valid implementation meets the following requirements:

The following is an example of a web service implementation that meets these requirements.

package org.jboss.quickstarts.ws.jaxws.samples.retail.profile;

import javax.ejb.Stateless;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;

@Stateless

@WebService(
    name = "ProfileMgmt",
    targetNamespace = "http://org.jboss.ws/samples/retail/profile",
    serviceName = "ProfileMgmtService")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public class ProfileMgmtBean {
    @WebMethod
    public DiscountResponse getCustomerDiscount(DiscountRequest request) {
        DiscountResponse dResponse = new DiscountResponse();
        dResponse.setCustomer(request.getCustomer());
        dResponse.setDiscount(10.00);
        return dResponse;
    }
}

The following is an example of the DiscountRequest class that is used by the ProfileMgmtBean bean in the previous example. The annotations are included for verbosity. Typically, the JAXB defaults are reasonable and do not need to be specified.

package org.jboss.test.ws.jaxws.samples.retail.profile;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlType;

import org.jboss.test.ws.jaxws.samples.retail.Customer;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(
  name = "discountRequest",
  namespace="http://org.jboss.ws/samples/retail/profile",
  propOrder = { "customer" }
)
public class DiscountRequest {

   protected Customer customer;

   public DiscountRequest() {
   }

   public DiscountRequest(Customer customer) {
      this.customer = customer;
   }

   public Customer getCustomer() {
      return customer;
   }

   public void setCustomer(Customer value) {
      this.customer = value;
   }

}

Packaging Your Deployment

The implementation class is wrapped in a JAR deployment. Any metadata required for deployment is taken from the annotations on the implementation class and the service endpoint interface. You can deploy the JAR using the management CLI or the management console, and the HTTP endpoint is created automatically.

The following listing shows an example of the structure for a JAR deployment of an EJB web service.

$ jar -tf jaxws-samples-retail.jar
org/jboss/test/ws/jaxws/samples/retail/profile/DiscountRequest.class
org/jboss/test/ws/jaxws/samples/retail/profile/DiscountResponse.class
org/jboss/test/ws/jaxws/samples/retail/profile/ObjectFactory.class
org/jboss/test/ws/jaxws/samples/retail/profile/ProfileMgmt.class
org/jboss/test/ws/jaxws/samples/retail/profile/ProfileMgmtBean.class
org/jboss/test/ws/jaxws/samples/retail/profile/ProfileMgmtService.class
org/jboss/test/ws/jaxws/samples/retail/profile/package-info.class

After creating a web service endpoint, either manually or using JAX-WS annotations, you can access its WSDL. This WSDL can be used to create the basic client application that will communicate with the web service. The process of generating Java code from the published WSDL is called consuming the web service. This happens in the following phases:

Create the Client Artifacts

Before you can create client artifacts, you need to create your WSDL contract. The following WSDL contract is used for the examples presented in the rest of this section.

The examples below rely on having this WSDL contract in the ProfileMgmtService.wsdl file.

The wsconsume.sh or wsconsume.bat tool is used to consume the abstract contract (WSDL) and produce annotated Java classes and optional sources that define it. The tool is located in the EAP_HOME/bin/ directory.

Both .java source files and compiled .class files are generated into the output/ directory within the directory where you run the command.

The wsconsume command generates all custom data types (JAXB annotated classes), the service endpoint interface, and a service factory class. These artifacts are used to build web service client implementations.

Construct a Service Stub

Web service clients use service stubs to abstract the details of a remote web service invocation. To a client application, a web service invocation looks like an invocation of any other business component. In this case the service endpoint interface acts as the business interface, and a service factory class is not used to construct it as a service stub.

The following example first creates a service factory using the WSDL location and the service name. Next, it uses the service endpoint interface created by wsconsume to build the service stub. Finally, the stub can be used just as any other business interface would be.

You can find the WSDL URL for your endpoint in the JBoss EAP management console. Select the Runtime tab, select your server, then under Subsystems, select Web Services and click View. Go to the Attributes tab to review the deployment details.

import javax.xml.ws.Service;
[...]
Service service = Service.create(
new URL("http://example.org/service?wsdl"),
new QName("MyService")
);
ProfileMgmt profileMgmt = service.getPort(ProfileMgmt.class);

// Use the service stub in your application

The client communicates with, and requests work from, the JAX-WS endpoint, which is deployed in the Java Enterprise Edition 7 container. For detailed information about the classes, methods, and other implementation details mentioned below, see the relevant sections of the Javadocs bundle included with JBoss EAP.

Overview

A Service is an abstraction which represents a WSDL service. A WSDL service is a collection of related ports, each of which includes a port type bound to a particular protocol and a particular endpoint address.

Usually, the Service is generated when the rest of the component stubs are generated from an existing WSDL contract. The WSDL contract is available via the WSDL URL of the deployed endpoint, or can be created from the endpoint source using the wsprovide tool in the EAP_HOME/bin/ directory.

This type of usage is referred to as the static use case. In this case, you create instances of the Service class which is created as one of the component stubs.

You can also create the service manually, using the Service.create method. This is referred to as the dynamic use case.

Usage

Static Use Case

The static use case for a JAX-WS client assumes that you already have a WSDL contract. This might be generated by an external tool or generated by using the correct JAX-WS annotations when you create your JAX-WS endpoint.

To generate your component stubs, you use the wsconsume tool included in EAP_HOME/bin. The tool takes the WSDL URL or file as a parameter, and generates multiple files, structured in a directory tree. The source and class files representing your Service are named _Service.java and _Service.class, respectively.

The generated implementation class has two public constructors, one with no arguments and one with two arguments. The two arguments represent the WSDL location (a java.net.URL) and the service name (a javax.xml.namespace.QName) respectively.

The no-argument constructor is the one used most often. In this case the WSDL location and service name are those found in the WSDL. These are set implicitly from the @WebServiceClient annotation that decorates the generated class.

@WebServiceClient(name="StockQuoteService", targetNamespace="http://example.com/stocks", wsdlLocation="http://example.com/stocks.wsdl")
public class StockQuoteService extends javax.xml.ws.Service
{
   public StockQuoteService() {
      super(new URL("http://example.com/stocks.wsdl"), new QName("http://example.com/stocks", "StockQuoteService"));
   }

   public StockQuoteService(String wsdlLocation, QName serviceName) {
      super(wsdlLocation, serviceName);
   }
   ...
}

For details about how to obtain a port from the service and how to invoke an operation on the port, see Dynamic Proxy. For details about how to work with the XML payload directly or with the XML representation of the entire SOAP message, see Dispatch.

Dynamic Use Case

In the dynamic case, no stubs are generated automatically. Instead, a web service client uses the Service.create method to create Service instances. The following code fragment illustrates this process.

URL wsdlLocation = new URL("http://example.org/my.wsdl");
QName serviceName = new QName("http://example.org/sample", "MyService");
Service service = Service.create(wsdlLocation, serviceName);

Handler Resolver

JAX-WS provides a flexible plug-in framework for message processing modules, known as handlers. These handlers extend the capabilities of a JAX-WS runtime system. A Service instance provides access to a HandlerResolver via a pair of getHandlerResolver and setHandlerResolver methods that can configure a set of handlers on a per-service, per-port or per-protocol binding basis.

When a Service instance creates a proxy or a Dispatch instance, the handler resolver currently registered with the service creates the required handler chain. Subsequent changes to the handler resolver configured for a Service instance do not affect the handlers on previously created proxies or Dispatch instances.

Executor

Service instances can be configured with a java.util.concurrent.Executor. The Executor invokes any asynchronous callbacks requested by the application. The setExecutor and getExecutor methods of Service can modify and retrieve the Executor configured for a service.

Dynamic Proxy

A dynamic proxy is an instance of a client proxy using one of the getPort methods provided in the Service. The portName specifies the name of the WSDL port the service uses. The serviceEndpointInterface specifies the service endpoint interface supported by the created dynamic proxy instance.

public <T> T getPort(QName portName, Class<T> serviceEndpointInterface)
public <T> T getPort(Class<T> serviceEndpointInterface)

The Service Endpoint Interface is usually generated using the wsconsume tool, which parses the WSDL and creates Java classes from it.

A typed method, which returns a port, is also provided. These methods also return dynamic proxies that implement the SEI. See the following example.

@WebServiceClient(name = "TestEndpointService", targetNamespace = "http://org.jboss.ws/wsref",
   wsdlLocation = "http://localhost.localdomain:8080/jaxws-samples-webserviceref?wsdl")

public class TestEndpointService extends Service {
    ...

    public TestEndpointService(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }

    @WebEndpoint(name = "TestEndpointPort")
    public TestEndpoint getTestEndpointPort() {
        return (TestEndpoint)super.getPort(TESTENDPOINTPORT, TestEndpoint.class);
    }
}

@WebServiceRef

The @WebServiceRef annotation declares a reference to a web service. It follows the resource pattern shown by the javax.annotation.Resource annotation defined in JSR 250.

Dispatch

XML web services use XML messages for communication between the endpoint, which is deployed in the Java EE container, and any clients. The XML messages use an XML language called Simple Object Access Protocol (SOAP). The JAX-WS API provides the mechanisms for the endpoint and clients to each be able to send and receive SOAP messages. Marshalling is the process of converting a Java Object into a SOAP XML message. Unmarshalling is the process of converting the SOAP XML message back into a Java Object.

In some cases, you need access to the raw SOAP messages themselves, rather than the result of the conversion. The Dispatch class provides this functionality. Dispatch operates in one of two usage modes, which are identified by one of the following constants.

Dispatch is a low-level API which requires clients to structure messages or payloads as XML, with strict adherence to the standards of the individual protocol and a detailed knowledge of message or payload structure. Dispatch is a generic class which supports input and output of messages or message payloads of any type.

Service service = Service.create(wsdlURL, serviceName);
Dispatch dispatch = service.createDispatch(portName, StreamSource.class, Mode.PAYLOAD);

String payload = "<ns1:ping xmlns:ns1='http://oneway.samples.jaxws.ws.test.jboss.org/'/>";
dispatch.invokeOneWay(new StreamSource(new StringReader(payload)));

payload = "<ns1:feedback xmlns:ns1='http://oneway.samples.jaxws.ws.test.jboss.org/'/>";
Source retObj = (Source)dispatch.invoke(new StreamSource(new StringReader(payload)));

Asynchronous Invocations

The BindingProvider interface represents a component that provides a protocol binding which clients can use. It is implemented by proxies and is extended by the Dispatch interface.

BindingProvider instances might provide asynchronous operation capabilities. Asynchronous operation invocations are decoupled from the BindingProvider instance at invocation time. The response context is not updated when the operation completes. Instead, a separate response context is made available using the Response interface.

public void testInvokeAsync() throws Exception {
   URL wsdlURL = new URL("http://" + getServerHost() + ":8080/jaxws-samples-asynchronous?wsdl");
   QName serviceName = new QName(targetNS, "TestEndpointService");
   Service service = Service.create(wsdlURL, serviceName);
   TestEndpoint port = service.getPort(TestEndpoint.class);
   Response response = port.echoAsync("Async");
   // access future
   String retStr = (String) response.get();
   assertEquals("Async", retStr);
}

@Oneway Invocations

The @Oneway annotation indicates that the given web method takes an input message but returns no output message. Usually, a @Oneway method returns the thread of control to the calling application before the business method is executed.

@WebService (name="PingEndpoint")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class PingEndpointImpl {
   private static String feedback;

   @WebMethod
   @Oneway
   public void ping() {
      log.info("ping");
      feedback = "ok";
   }

   @WebMethod
   public String feedback() {
      log.info("feedback");
      return feedback;
   }
}

Timeout Configuration

Two different properties control the timeout behavior of the HTTP connection and the timeout of a client which is waiting to receive a message. The first is javax.xml.ws.client.connectionTimeout and the second is javax.xml.ws.client.receiveTimeout. Each is expressed in milliseconds, and the correct syntax is shown below.

public void testConfigureTimeout() throws Exception {
   //Set timeout until a connection is established
   ((BindingProvider)port).getRequestContext().put("javax.xml.ws.client.connectionTimeout", "6000");

   //Set timeout until the response is received
   ((BindingProvider) port).getRequestContext().put("javax.xml.ws.client.receiveTimeout", "1000");

   port.echo("testTimeout");
}

JBossWS enables extra setup configuration data to be predefined and associated with an endpoint implementation. Predefined endpoint configurations can be used for JAX-WS client and JAX-WS endpoint setup. Endpoint configurations can include JAX-WS handlers and key/value properties declarations. This feature provides a convenient way to add handlers to web service endpoints and to set key/value properties that control JBossWS and Apache CXF internals.

The webservices subsystem allows you to define named sets of endpoint configuration data. Each endpoint configuration must have a unique name within the subsystem. The org.jboss.ws.api.annotation.EndpointConfig annotation can then be used to assign an endpoint configuration to a JAX-WS implementation in a deployed application. See Assigning a Configuration for more information on assigning endpoint configurations.

There are two predefined endpoint configurations in the default JBoss EAP configuration:

Add an Endpoint Configuration

You can add a new endpoint configuration using the management CLI.

/subsystem=webservices/endpoint-config=My-Endpoint-Config:add

Configure an Endpoint Configuration

You can add key/value property declarations for the endpoint configuration using the management CLI.

/subsystem=webservices/endpoint-config=Standard-Endpoint-Config/property=PROPERTY_NAME:add(value=PROPERTY_VALUE)

You can also configure handler chains and handlers for these endpoint configurations.

Remove an Endpoint Configuration

You can remove a endpoint configuration using the management CLI.

/subsystem=webservices/endpoint-config=My-Endpoint-Config:remove

Each endpoint configuration can be associated with PRE or POST handler chains. Each handler chain may include JAX-WS-compliant handlers to perform additional processing on messages. For outbound messages, PRE handler chain handlers are executed before any handler attached to the endpoints using standard JAX-WS means, such as the @HandlerChain annotation. POST handler chain handlers are executed after usual endpoint handlers. For inbound messages, the opposite applies.

Endpoint --> PRE Handlers --> Endpoint Handlers --> POST Handlers --> ... --> Client

Client --> ... --> POST Handlers --> Endpoint Handlers --> PRE Handlers --> Endpoint

Add a Handler Chain

You can add a POST handler chain to an endpoint configuration using the following management CLI command.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain:add

You can add a PRE handler chain to an endpoint configuration using the following management CLI command.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/pre-handler-chain=my-pre-handler-chain:add

Configure a Handler Chain

Use the protocol-bindings attribute to set which protocols trigger the handler chain to start.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain:write-attribute(name=protocol-bindings,value=##SOAP11_HTTP)

See the handlers section for information on configuring handlers for a handler chain.

Remove a Handler Chain

You can remove a handler chain using the management CLI.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain:remove

A JAX-WS handler is added to a handler chain and specifies the fully-qualified name of the handler class. When the endpoint is deployed, an instance of that class is created for each referencing deployment. Either the deployment class loader or the class loader for the org.jboss.as.webservices.server.integration module must be able to load the handler class.

See the Handler Javadocs for a listing of the available handlers.

Add a Handler

You can add a handler to a handler chain using the following management CLI command. You must provide the class name of the handler.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain/handler=my-handler:add(class="com.arjuna.webservices11.wsarj.handler.InstanceIdentifierInHandler")

Configure a Handler

You can update the class for a handler using the management CLI.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain/handler=my-handler:add(class="org.jboss.ws.common.invocation.RecordingServerHandler")

Remove a Handler

You can remove a handler using the management CLI.

/subsystem=webservices/endpoint-config=My-Endpoint-Config/post-handler-chain=my-post-handler-chain/handler=my-handler:

The rewriting of the <soap:address> element of endpoints published in WSDL contracts is supported. This feature is useful for controlling the server address that is advertised to clients for each endpoint.

The following table lists the attributes that can be configured for this feature.

You can use the management CLI to update these attributes. For example:

/subsystem=webservices:write-attribute(name=wsdl-uri-scheme, value=https)

Each web service endpoint is exposed through the deployment that provides the endpoint implementation. Each endpoint can be queried as a deployment resource. Each web service endpoint specifies a web context and a WSDL URL. You can access this runtime information using the management CLI or the management console.

The following management CLI command shows the details of the TestService endpoint from the jaxws-samples-handlerchain.war deployment.

/deployment="jaxws-samples-handlerchain.war"/subsystem=webservices/endpoint="jaxws-samples-handlerchain:TestService":read-resource(include-runtime=true)
{
    "outcome" => "success",
    "result" => {
        "average-processing-time" => 23L,
        "class" => "org.jboss.test.ws.jaxws.samples.handlerchain.EndpointImpl",
        "context" => "jaxws-samples-handlerchain",
        "fault-count" => 0L,
        "max-processing-time" => 23L,
        "min-processing-time" => 23L,
        "name" => "TestService",
        "request-count" => 1L,
        "response-count" => 1L,
        "total-processing-time" => 23L,
        "type" => "JAXWS_JSE",
        "wsdl-url" => "http://localhost:8080/jaxws-samples-handlerchain?wsdl"
    }
}

/subsystem=webservices:write-attribute(name=statistics-enabled,value=true)

You can also view runtime information for web services endpoints from the Runtime tab of the management console. Select the server, then select Subsystems Web Services View. The runtime statistics are shown on the Statistics tab, and the endpoint details are shown on the Attributes tab.

The explicit configuration assignment is meant for developers that know in advance their endpoint or client has to be set up according to a specified configuration. The configuration is coming from either a descriptor that is included in the application deployment, or is included in the webservices subsystem.

In some cases, the application developer might not be aware of the configuration that will need to be used for its client and endpoint implementation. In other cases, explicit usage of the JBossWS API might not be accepted because it is a compile-time dependency. To cope with such scenarios, JBossWS allows including default client, jaxws-client-config.xml, and endpoint, jaxws-endpoint-config.xml, descriptors within the application in its root directory. These are parsed for getting configurations whenever a configuration file name is not specified.

<config-file>WEB-INF/jaxws-endpoint-config.xml</config-file>

If the configuration name is not specified, JBossWS automatically looks for a configuration named as:

No automatic configuration name is selected for Dispatch clients.

For example, an endpoint implementation class org.foo.bar.EndpointImpl, for which no predefined configuration is explicitly set, will cause JBossWS to look for a org.foo.bar.EndpointImpl named configuration within a jaxws-endpoint-config.xml descriptor in the root of the application deployment. Similarly, on the client side, a client proxy implementing org.foo.bar.Endpoint interface will have the setup read from a org.foo.bar.Endpoint named configuration in the jaxws-client-config.xml descriptor.

JBossWS falls back to getting predefined configurations from the container whenever no explicit configuration has been provided and the default descriptors are either not available or do not contain relevant configurations. This behavior gives additional control on the JAX-WS client and endpoint setup to administrators since the container can be managed independently from the deployed applications.

JBossWS accesses the webservices subsystem for an explicitly named configuration. The default configuration names used are:

Dispatch clients are not automatically configured. If no configuration is found using names computed as above, the Standard-Client-Config and Standard-Endpoint-Config configurations are used for clients and endpoints respectively.

To configure deployment dependencies, add them to the MANIFEST.MF file. For example:

Manifest-Version: 1.0
Dependencies: org.jboss.ws.cxf.jbossws-cxf-client services export,foo.bar

This MANIFEST.MF file declares dependencies on the org.jboss.ws.cxf.jbossws-cxf-client and foo.bar modules. For more information on declaring dependencies in a MANIFEST.MF file, including the export and services options, see Add a Dependency Configuration to MANIFEST.MF in the JBoss EAP Development Guide.

When using annotations on the endpoints and handlers, for example, Apache CXF endpoints and handlers, add the proper module dependency in your manifest file. If you skip this step, your annotations are not picked up and are completely, silently ignored.

Dependencies: com.sun.xml.bind services export

Dependencies: org.apache.cxf services

Dependencies: org.jboss.ws.cxf.jbossws-cxf-client services

Dependencies: my.org annotations

In some circumstances, the convenient approach of setting module dependencies in the MANIFEST.MF file might not work. For example, setting dependencies in the MANIFEST.MF file does not work when importing and exporting specific resources from a given module dependency. In these scenarios, add a jboss-deployment-structure.xml descriptor file to your deployment and set module dependencies in it.

For more information on using jboss-deployment-structure.xml, see Add a Dependency Configuration to the jboss-deployment-structure.xml in the JBoss EAP Development Guide.

Web services support many real-world scenarios requiring WS-Security functionality. These scenarios include signature and encryption support through X509 certificates, authentication and authorization through username tokens, and all WS-Security configurations covered by the WS-SecurityPolicy specification.

For other WS-* features, the core of WS-Security functionality is provided through the Apache CXF engine. In addition, the JBossWS integration adds a few configuration enhancements to simplify the setup of WS-Security enabled endpoints.

WS-Trust is a web service specification that defines extensions to WS-Security. It is a general framework for implementing security in a distributed system. The standard is based on a centralized Security Token Service (STS), which is capable of authenticating clients and issuing tokens containing various types of authentication and authorization data. The specification describes a protocol used for issuance, exchange, and validation of security tokens. The following specifications play an important role in the WS-Trust architecture:

The WS-Trust extensions address the needs of applications that span multiple domains and requires the sharing of security keys. This occurs by providing a standards-based trusted third party web service (STS) to broker trust relationships between a web service requester and a web service provider. This architecture also alleviates the pain of service updates that require credential changes by providing a common location for this information. The STS is the common access point from which both the requester and provider retrieves and verifies security tokens.

There are three main components of the WS-Trust specification:

The following section explains a basic WS-Trust scenario. For advanced scenarios, see Advanced WS-Trust Scenarios.

The Security Token Service (STS) is the core of the WS-Trust specification. It is a standards-based mechanism for authentication and authorization. The STS is an implementation of the WS-Trust specification’s protocol for issuing, exchanging, and validating security tokens, based on token format, namespace, or trust boundaries. The STS is a web service that acts as a trusted third party to broker trust relationships between a web service requester and a web service provider. It is a common access point trusted by both requester and provider to provide interoperable security tokens. It removes the need for a direct relationship between the requestor and provider. The STS helps ensure interoperability across realms and between different platforms because it is a standards-based mechanism for authentication.

The STS’s WSDL contract defines how other applications and processes interact with it. In particular, the WSDL defines the WS-Trust and WS-Security policies that a requester must fulfill to successfully communicate with the STS’s endpoints. A web service requester consumes the STS’s WSDL and, with the aid of an STSClient utility, generates a message request compliant with the stated security policies and submits it to the STS endpoint. The STS validates the request and returns an appropriate response.

You can configure a JAX-WS handler to log messages that are passed to it. This approach is portable as the handler can be added to the desired client and endpoints programatically by using the @HandlerChain JAX-WS annotation.

The predefined client and endpoint configuration mechanism allows you to add the logging handler to any client and endpoint combination, or to only some of the clients and endpoints. To add the logging handler to only some of the clients or endpoints, use the @EndpointConfig annotation and the JBossWS API.

The org.jboss.ws.api.annotation.EndpointConfig annotation is used to assign an endpoint configuration to a JAX-WS endpoint implementation. When assigning a configuration that is defined in the webservices subsystem, only the configuration name is specified. When assigning a configuration that is defined in the application, the relative path to the deployment descriptor and the configuration name must be specified.

Apache CXF also comes with logging interceptors that can be used to log messages to the console, client log files, or server log files. Those interceptors can be added to client, endpoint, and buses in multiple ways, including:

The JBossWS server-side integration with Apache CXF takes care of internally creating proper Apache CXF structures for the provided web service deployment. If the deployment includes multiple endpoints, they will all exist within the same Apache CXF Bus, which is separate from other deployments' bus instances.

While JBossWS sets sensible defaults for most of the Apache CXF configuration options on the server side, users might want to fine-tune the Bus instance that is created for their deployment; a jboss-webservices.xml descriptor can be used for deployment-level customizations.
