Chapter 1. Introduction
Copiar enlace

JBoss Enterprise Application Platform is the open source implementation of the Java EE suite of services. It comprises a set of offerings for enterprise customers who are looking for preconfigured profiles of JBoss Enterprise Middleware components that have been tested and certified together to provide an integrated experience. Its easy-to-use server architecture and high flexibility makes JBoss the ideal choice for users just starting out with J2EE, as well as senior architects looking for a customizable middleware platform.
Because it is Java-based, JBoss Enterprise Application Platform is cross-platform, easy to install and use on any operating system that supports Java. The readily available source code is a powerful learning tool to debug the server and understand it. It also gives you the flexibility to create customized versions for your personal or business use.

Chapter 2. Pre-Requisites
Copiar enlace

The JBoss Enterprise Application Platform 5 binaries require around 500MB of disk space. The main requirement of the Platform is RAM. At least 4GB is necessary to comfortably run a 64-bit developer workstation running the production server profile with JBoss Developer Studio. A 32-bit JVM uses less resources than a 64-bit JVM, but does not provide large heaps. A server with 2GB and swap space can be used for testing and development.

There are three installation methods:
ZIP Installation
The ZIP installation method is the easiest and quickest if you are familiar with JBoss technologies, or if you are looking for a light-weight method for testing or development. This method requires some post-installation configuration. For ZIP installation instructions refer to Chapter 4, ZIP Installation from the Red Hat Customer Portal .
RPM Installation
RPM installation is suitable for production deployment on Red Hat Enterprise Linux systems. RPM installation leverages the benefits of RPM for updating, system management, and integration with administration tools. This method requires some post-installation configuration. For RPM installation instructions refer to Chapter 5, RPM Installation via Red Hat Network.
Graphical Installer
The graphical installer simplifies the installation and configuration process. In addition to installing the base files, the installer offers automation of optional component installation, and basic out-of-the-box security configuration. For graphical installer instructions refer to Chapter 6, Installation using the Graphical Installer.

    This creates the jboss-eap-<release> directory, with an installation of JBoss Enterprise Application Platform using JBoss WS Native as the Web Services Stack, and JBoss Messaging as the messaging provider.

  3. Optional: Use JBoss WS CXF as the Web Service stack

    You need Apache Ant installed and configured on your machine to perform this task.
    1. Extract jboss-ep-ws-cxf-<release>.GA-installer.zip and move the jbossws-cxf-installer into the jboss-as directory of the Enterprise Platform.
    2. At the command line go to the directory jboss-as/jbossws-cxf-installer and run the command ant.
      Result:

      An installer script replaces WS Native with WS CXF.

  4. Optional: Install PicketLink Federation

    1. To install PicketLink Federation, copy the $JBOSS_HOME/picketlink/picketlink-federation/picketlink-core-<VERSION>.jar file to $JBOSS_HOME/common/lib and copy $JBOSS_HOME/picketlink/picketlink-federation/picketlink-jbas5-VERSION.jar file to $JBOSS_HOME/common/lib;
    2. Optionally, deploy the PicketLink web applications of your choice to the server by copying their directories to $JBOSS_HOME/jboss-as/server/PROFILE/deploy/ directory. To do so, run the following command with the WEBAPP substituted with the application directory (idp.war, pdp.war, or picketlink-sts.war): 
      cp -r $JBOSS_HOME/picketlink/picketlink-federation-webapps/WEBAPP $JBOSS_HOME/jboss-as/server/PROFILE/deploy/

Warning

By default, the Legacy Invoker Servlet is exposed on all network interfaces and deserializes objects sent to it via HTTP. In addition to applying the latest security patches, we recommended that you only bind this servlet to the loopback network interface so that remote users cannot use it perform deserialization attacks. Failure to restrict access to this servlet could lead to remote code execution being allowed to remote attackers.
For instructions on binding this servlet to the loopback network interface, see https://access.redhat.com/solutions/45530.

Chapter 8. Optional Components
Copiar enlace

8.1. Web Services Stack
Copiar enlace

This release provides two options for the Web Services stack:
JBoss Web Services Native
JBoss Web Services Native is the Java EE 5-compliant JBoss implementation of web services standards. It is the only web services stack for versions of JBoss Enterprise Application Platform prior to 5.1, and is the default web services stack in JBoss Enterprise Application Platform 5.
JBoss Web Services CXF
JBoss Web Services CXF provides most of the features available in Apache CXF (including WS-Security, WS-Policy, WS-Addressing, WS-ReliableMessaging, basic WS-Trust, MTOM), plus common JBoss Web Services stack features like endpoint metrics, record management and endpoint address rewrite. JBoss Enterprise Application Platform 5 introduces JBoss Web Services CXF stack as an optional Web Services stack.
Select which Web Services stack to use during installation. To change the Web Services stack at a later date, reinstall the Platform.

8.2. PicketLink Federation
Copiar enlace

This release includes PicketLink Federation as a supported product.
PicketLink Federation brings Identity Federation and Single Sign-on to the Platform, with support for SAML 2.0, WS-Trust 1.3, and XACML 2.0 (via JBossXACML).
Refer to the installation sections for PicketLink installation instructions.

8.3. Native Components
Copiar enlace

The Native Components Package

The Native Components package is an optional component for the JBoss Enterprise Application Platform that incorporates native operating system components and connectors for web servers, including JBoss Native, mod_jk, mod_cluster, NSAPI for Solaris, NSAPI for Oracle iPlanet Web Server, ISAPI for Windows and HornetQ LibAIO Native for Red Hat Enterprise Linux.

Installing JBoss Native results in higher server performance, as native operating system code becomes available for the server to optimize tasks.
For more information on configuring the web server connectors, refer to the HTTP Connectors Load Balancing Guide.

Native Components Manifest

  • JBoss Native consists of the Apache Portable Runtime (APR), OpenSSL and Tomcat Native (TC-native);
    • Apache Portable Runtime (APR) provides superior scalability, performance, and improved integration with native server technologies. APR is a highly portable library that is at the heart of Apache HTTP Server 2.x. It enables access to advanced IO functionality (for example: sendfile, epoll and OpenSSL), Operating System level functionality (for example: random number generation and system status), and native process handling (shared memory, NT pipes and Unix sockets).
    • OpenSSL implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols and includes a basic cryptographic library.
    • Tomcat Native (TC-Native) is a Java Native Interface (JNI) that provides much of Tomcat's core functionality in native code rather than Java. This allows for an overall increase in the speed of a server.
  • mod_jk connects the Tomcat JSP container to the Apache webserver, providing load-balancing.
  • mod_cluster is an httpd-based load balancer. In contrast to mod_jk, mod_cluster creates a feedback loop between the proxy server and the worker nodes, enabling intelligent load distribution and routing within a load-balancing cluster.
  • ISAPI is a connector for the Microsoft IIS web server.
  • HornetQ LibAIO is used as a bridge between HornetQ and Linux LibAIO. It is used in HornetQ's high performance journal, when configured.

8.3.1. Red Hat Enterprise Linux-specific notes
Copiar enlace

Red Hat Enterprise Linux includes some of the Native Components in the base operating system. These include OpenSSL and the Apache Portable Runtime (APR). The Apache Portable Runtime is provided by the packages apr and apr-util.
If the server is started without the apr and apr-util packages installed, a message similar to the following will appear in logs: 
WARN [AprLifecycleListener] The Apache Tomcat Native library which allows optimal performance
  in production environments was not found on the java.library.path:
  /home/eapuser/jboss-eap-5.2/native/lib.
Copy to Clipboard Toggle word wrap

8.3.2. Hewlett Packard HP-UX-specific notes
Copiar enlace

OpenSSL libraries are not provided in the Natives package. Instead the library provided with the operating system is used.

8.3.3. Solaris-specific notes
Copiar enlace

Both the 32-bit and 64-bit versions of jboss-ep-native can be installed on the same machine. The libraries for each are separated by the directories lib and lib64 respectively and each is automatically loaded depending on the JVM version that is used.
To install both 32-bit and 64-bit versions of jboss-ep-native, use unzip -qo. The -o option ensures that one version of the package does not replace another during the installation.

8.3.4. Native Components Installation

This chapter provides information for administrators who plan to move their enterprise servers from JBoss Enterprise Application Platform 4.2 or 4.3 to the new Enterprise Application Platform 5.
The first section covers new features available in Enterprise Application Platform 5. The second section covers the changes to configuration, administration, and application deployment between Enterprise Application Platform 4.x and Enterprise Application Platform 5.
If you require further information, refer to the relevant guides provided in this release.

Note

JBoss Enterprise Application 5 is a major release, and includes major changes from JBoss Enterprise Application Platform 4.3. With the release of JBoss Enterprise Application Platform 5.1.1 onwards, an RPM upgrade path from JBoss Enterprise Application Platform 4.3 is no longer available.
JBoss Enterprise Application Platform 4.3 customers that want to upgrade to JBoss Enterprise Application Platform 5 should back-up their production systems and proceed with installing the platform using an installation option described in Part I, “Installing JBoss Enterprise Application Platform 5”.

11.1. What's New in Enterprise Application Platform 5
Copiar enlace

This section provides an overview of the components of Enterprise Application Platform 5, and the changes to each component between version 4.x and 5.

11.1.1. JBoss Application Server 5 GA
Copiar enlace

JBoss Application Server 5 is the next generation of the JBoss Application Server built on top of a new kernel architecture, the JBoss Microcontainer. The JBoss Microcontainer is a lightweight container for managing the deployment, configuration and life cycle of Plain Old Java Objects (POJOs). While remaining compatible with the 4.x-based JMX kernel, the Microcontainer integrates with the JBoss framework for Aspect Oriented Programming, JBoss AOP. JMX support remains strong in EAP 5, and MBean services written against the old Microkernel work as expected. Further, it lays the groundwork for Java EE 6 profile-oriented configurations and embedded EAP, which will allow for fine grained selection of services for both unit testing and embedded scenarios.
11.1.1.1. ProfileService-based Deployment Configuration
Copiar enlace
Definitions for both non-kernel deployers and their deployment are now contained in a Profile obtained from the ProfileService. The ProfileService replaces EAP 4.x server configuration. In EAP 4.x, a server configuration was a collection of services and applications loaded from the deploy directory by the deployment scanner service. Enterprise Application Platform 5 uses more active profiles, which may depend on other sub-profiles.
The main profile is the server profile, which is based on the ${jboss.server.name}. This profile has three sub-profiles:
  • bootstrap — representing conf/jboss-service.xml
  • deployers — the deployers/ directory
  • applications — a hot-deployment profile for the deploy/ and additional user directories
A profile generally represents a named collection of deployments on a server. A profile can also apply certain behaviors to the deployments that it manages. Some profiles, such as the application profile, provide hot-deployment checks and allow remote distribution of deployed applications via the DeploymentManager. Other profiles can provide a farming service to distribute deployments over a cluster. The ProfileService also provides the ManagementView for ManagedDeployments/ManagedObjects used by the Enterprise Application Admin Console (admin-console).

11.1.2. Enterprise Java Beans (EJB) 3.0
Copiar enlace

JBoss EJB 3.0, an implementation of the latest revision of the EJB specification, is a deep overhaul and simplification of earlier versions of the EJB specification. It simplifies development, facilitates a test driven approach, and focuses more on writing POJOs rather than coding against complex EJB APIs.

11.1.3. Java Enterprise Edition 5 Compliance
Copiar enlace

JBoss Enterprise Application Platform 5 is a fully-certified Java EE 5 implementation. It uses the microcontainer to integrate enterprise services with a Servlet/JSP container, EJB container, deployers and management utilities, providing a standard Java EE environment with the flexibility to deploy additional services on top of Java EE to give you the functionality you need. For further compatibility details, read http://java.sun.com/javaee/overview/compatibility.jsp page.

11.1.4. Seam 2.2.0.GA
Copiar enlace

Seam is an application framework for Java Enterprise Edition. It integrates technologies such as Asynchronous JavaScript and XML (AJAX), JavaServer Faces (JSF), Java Persistence (JPA), Enterprise JavaBeans 3.0 (EJB) and Business Process Management (BPM). Seam enables developers to assemble complex web applications using simple annotated Java classes, a rich set of UI components, and very little XML.

11.1.5. RESTEasy 1.1.GA
Copiar enlace

RESTEasy provides several frameworks to help you build RESTful Web Services and RESTful Java applications. It is a fully-certified, portable implementation of the JAX-RS specification, which defines a Java API for RESTful Web Services over the Hypertext Transfer Protocol (HTTP).

11.1.6. Enhanced Enterprise GUI Installer
Copiar enlace

The Enterprise Installer retains the familiar Enterprise Application Platform 4.3 interface but includes enhancements to provide you with a complete Enterprise Application Platform 5 installation. The installer is localized and provides you with secure JMX, Web and Admin Consoles.
The new Enterprise Installer also presents users with the opportunity to install the optional Native package, which includes JBoss Native and mod_jk. The Native package helps users who wish to use Tomcat or JBoss Web with the HTTP daemon.

11.1.7. Enterprise Application Platform Admin Console
Copiar enlace

A new Admin Console is being introduced in this Enterprise Application Platform release. The admin-console enables configuration and management of a single Enterprise Application Platform server instance. See Section 11.3, “Admin Console” for more information about this new management console.

11.1.8. JBoss Transactions includes Java Transaction Service
Copiar enlace

JBoss Transactions now includes the Java Transaction Service and the XML Transaction Service. The Java Transaction Service handles distributed, interoperable transactions between Enterprise JavaBean containers. The XML Transaction Service handles transactions for Web Services.

11.1.9. Distribution with Red Hat Signed JARs
Copiar enlace

JAR files included with JBoss Enterprise Application Platform are digitally signed by Red Hat. This gives you an additional level of security about the source and identity of the code executing on your systems.
For the complete technology matrix and information on the revision level of included components please refer to the Release Notes.

11.2. What's Different in Enterprise Application Platform 5
Copiar enlace

The distribution layout and configuration information in the Enterprise Application Platform 5 distribution are similar to the Enterprise Application Platform 4.x series with some notable differences. This section highlights the differences at a glance.

11.2.1. Differences in the Distribution Layout
Copiar enlace

The directory structure of jboss-as directory is summarized below.
  • /bin — contains start scripts and run.jar
  • /client — contains client JARs.

    Note

    Previously, JBoss client libraries were bundled in jbossall-client.jar. Rather than including them, jbossall-client.jar now references them through a Classpath manifest entry. This enables granular updating of libraries without requiring replacement of all libraries. It requires that you have the jbossall-client.jar, which now acts as a map or index, as well as the actual client/*.jar libraries.
  • /common/lib — contains shared libraries common to various configurations have been moved to this new shared location. This eliminates the need for multiple copies of the same library in the distribution.
    The location of the common library directory is controlled with the following properties:
    • jboss.common.base.url — the default value is ${jboss.home.url}/common
    • jboss.common.lib.url — the default value is ${jboss.common.base.url}/lib
    You can set these properties in run.conf under JAVA_OPTS with the -D flag: 
    JAVA_OPTS="[...] -Djboss.common.base.url=$URL1 -Djboss.common.lib.url=$URL2"
    Copy to Clipboard Toggle word wrap
    The common library directory is shared by all configuration types except for the minimal configuration. The common library is referenced at the beginning of every configuration's conf/jboss-service.xml 
    <classpath codebase="${jboss.server.lib.url}" archives="*"/>
    Copy to Clipboard Toggle word wrap
    The library directory of the individual directory remains in place, although in some cases (as in $JBOSS_HOME/server/default/lib/) it is an empty directory.
  • /docs — contains schemas, document type declarations, examples and licenses. Most deployment descriptors now use XML Schema Definitions (XSDs). One exception is jboss-app, which uses jboss-app_5_0.dtd. JBoss Web uses jboss-web_5_1.xsd. For Enterprise JavaBeans 3.0 deployments, jboss_5_1.xsd is the recommended schema. Enterprise JavaBeans 2.0 deployments must use jboss_x_x.dtd.
  • /lib — contains the core bootstrap JARs. These have been changed slightly to accommodate the Microcontainer and the division of jboss-common.
  • /server — contains directories for configuring the server:
    • $PROFILE — contains the configuration details of a particular server profile
      • /conf
        • bootstrap.xml — a new kernel bootstrap configuration that refers to other configuration files containing the beans to set up each individual subsystem.
        • bindingservice.beans
          • /META-INF
            • bindings-jboss-beans.xml — contains required port bindings.
          • jboss-bindingservice.jar
        • /bootstrap
          • vfs.xml — initializes the virtual file system
          • classloader.xml
          • aop.xml
          • jmx.xml — legacy JMX support.
          • deployers.xml
          • profile-repository.xml — the ProfileService enabled deployment repository.
        • jax-ws-catalog.xml — an Oasis Catalog-driven Schema/DTD namespace configuration file.
        • jbossts-properties.xml — contains new JBossTS properties.
        • jboss-service.xml — contains legacy static managed beans to retain compatibility.
        • jndi.properties — contains JNDI configuration properties.
        • log4j.xml — contains log4j configuration information.
        • login-config.xml — contains JAAS login configuration information.
        • /props — contains default JAAS login properties files.
        • standardjbosscmp-jdbc.xml — contains CMP2 configuration information.
        • standardjboss.xml — contains Enterprise JavaBean 2.0 configuration information.
        • /xmdesc — contains legacy XML managed bean descriptors.
      • /deploy
        • jca-jboss-beans.xml
        • hdscanner-jboss-beans.xml — contains the hot-deployment scanner.
        • legacy-invokers-service.xml
        • profileservice-jboss-beans.xml
        • remoting-jboss-beans.xml
        • transaction-jboss-beans.xml
        • vfs-jboss-beans.xml
      • /deployers — contains new VDF deployers.
        • /bsh-deployer — contains the beanshell deployer.
        • ejb3.deployer — contains Enterprise JavaBean 3.0 deployers.
        • jboss-aop-jboss5.deployer — contains the aspect deployer.
        • jboss-jca.deployer — contains the JCA deployers.
        • jbossweb.deployer — contains the WAR deployers.
        • jbossws.deployer — contains the web service deployers.
        • seam.deployer — contains the Seam deployer.
        • clustering-deployers-jboss-beans.xml
        • dependency-deployers-jboss-beans.xml
        • directory-deployer-jboss-beans.xml
        • ear-deployer-jboss-beans.xml
        • ejb-deployer-jboss-beans.xml
        • hibernate-deployer-jboss-beans.xml
        • logbridge-boss-beans.xml
        • jsr77-deployers-jboss-beans.xml — contains JSR-77 (J2EE Management) support.

        • xnio.deployer
        • jboss-threads.deployer
      • /lib — contains static library JARs. Some JARs that were previously located in this directory have been moved into the top-level common/lib directory.

11.2.2. Standard and Web Configuration
Copiar enlace

Two additional server configurations are distributed with Enterprise Application Platform 5: standard and web.
The standard configuration is certified for Java EE 5 compliance. This configuration enables both call-by-value and deployment isolation by default. Support for RMI-IIOP (Remote Method Invocation over the Internet Inter-Orb Protocol) and Java UDDI (Universal Description, Discovery and Integration), as in the all configuration type, is also enabled.
The web configuration is lightweight. It was created around JBoss Web and provides the services required for web application deployment and only a subset of Java EE technologies. This profile does not include JBoss Transaction JTS or XTS, Enterprise Java Bean 1.x or 2.x capabilities, JBoss Messaging, JCA, or JBoss IIOP.

11.2.3. Differences in Application Server Configuration Files
Copiar enlace

11.2.3.1. General
Copiar enlace
  • A reminder that the RPM and ZIP distributions of the Enterprise Application Platform are shipped with authentication enabled for the JMX Console, Web Console, JMX Invoker, Admin Console, HTTP Invoker and Profile Service. No user accounts are active by default to assist in preventing default user and password-based attacks.
  • shutdown.sh now accepts a JNDI URL, as follows: 
    shutdown.sh -s http://localhost:8080/invoker/JNDIFactory -S
    Copy to Clipboard Toggle word wrap
    Where -s defines the server name to perform an operation on; -S specifies the shutdown operation.
  • If a user omits the -c option when starting an instance of JBoss Application Server in Enterprise Application Platform 4.x, the production configuration was started by default. In JBoss Enterprise Application Platform 5, default configuration is used when a user omits the -c option.
  • bin/run.conf now uses a Java heap size of 1303 MB. This is consistent across all configurations.
  • Document Type and Schema Declarations have been updated.
  • The production server profile provided with Enterprise Application Platform 5 restricts the classes served on port 8083. If Remote Method Invocation (RMI) is being used, you may need to make this port available to clients. This option can be set in production/conf/jboss-service.xml: 
    <!-- Should non-EJB .class files be downloadable -->
   <attribute name="DownloadServerClasses">false</attribute>
    Copy to Clipboard Toggle word wrap
  • The cluster-safe UUID generator can now be used from server/production/deploy/uuid-key-generator.sar/META-INF/jboss-service.xml.
  • The delay period for server/production/deploy/hdscanner-jboss-beans.xml to rescan for deployment changes has been increased to 60 seconds from the previous 5 second delay period. 
    <!-- Frequency in milliseconds to rescan the URLs for changes-->
   <property name="scanPeriod">60000</property>
    Copy to Clipboard Toggle word wrap
11.2.3.2. J2EE Connector Architecture
Copiar enlace
  • jboss-ra.xml can now be used to override the properties specified in *-ra.xml.
    The jboss-ra.xml file should be in the META-INF directory of the resource adapter whose properties you wish to override, alongside the *-ra.xml file.
    Specify a corresponding <ra-config-property> in the jboss-ra.xml file for each property you wish to override. An example follows:

    Example 11.1. Representative excerpt from resource adapter *-ra.xml file

    <config-property>
  <config-property-name>StringRAR</config-property-name>
  <config-property-type>java.lang.String</config-property-type>
  <config-property-value>StringFromRARProperties</config-property-value>
</config-property>
    Copy to Clipboard Toggle word wrap

    Example 11.2. Representative excerpt from a corresponding jboss-ra.xml file

    <ra-config-property>
  <ra-config-property-name>StringRAR</ra-config-property-name>
  <ra-config-property-type>java.lang.String</ra-config-property-type>
  <ra-config-property-value>XMLOVERRIDE</ra-config-property-value>
</ra-config-property>
    Copy to Clipboard Toggle word wrap
    The complete source for a working example can be viewed in the test case for this feature at https://anonsvn.jboss.org/repos/jbossas/trunk/testsuite/src/resources/jcaprops/xmloverride/META-INF/.
  • Support has been added for defining dependencies in J2EE Connector Architecture (JCA) adapters.
  • server/production/deploy/jca-jboss-beans.xml disables debug monitoring of JCA and database connections: 
    <!-- Whether to track unclosed connections and close them -->
<property name="debug">false</property>
    Copy to Clipboard Toggle word wrap
    This disables the application server's debug support. Disabling this means that the origin of obtained database connections and connection leaks cannot be tracked. Unclosed managed database connections are still returned to the connection pool, regardless of this attribute's value.
11.2.3.3. Web
Copiar enlace
  • For JavaServer Pages-based pages, the default setting for DeleteWorkDirOnContextDestroy is false. Set this to true to enable a faster, simpler page recompilation check, or if you are using JSP settings that require recompilation.
  • emptySessionPath="true" no longer sets the cookie path / by default. Instead, the cookie path is set via the <SessionCookie path="/" /> in the Context element. Session cookies are now scoped to the context by default.
  • emptySessionPath no longer affects whether Session IDs are recycled. This is now handled by the org.apache.catalina.connector.Request.SESSION_ID_CHECK system property. If set to true, the Servlet container verifies that a Session ID does not yet exist in a particular context before creating a session with that ID. You can set this property in the jboss-as/bin/run.conf file using the -D switch.
11.2.3.4. Clustering
Copiar enlace
  • Clustering configurations have been moved to a new /deploy/cluster directory. 
    cluster
   |-- deploy-hasingleton-jboss-beans.xml
   |-- farm-deployment-jboss-beans.xml
   |-- ha-legacy-jboss-beans.xml

    Copy to Clipboard Toggle word wrap
  • A separate cache is now used for Clustered Single Sign-On (SSO).
  • UseJK, snapshot mode and snapshot interval can now be configured on a per-application basis. The default value for UseJK depends upon whether the jvmRoute is set.
  • The default setting for session replication is now total replication instead of buddy replication.
  • loopback is now set to true for all JGroups User Datagram Protocol stacks.
  • The jboss.jgroups.udp.mcast_port property is now used to configure the multicast port. The -m option to the run.sh or run.bat script now sets jboss.jgroups.udp.mcast_port instead of jgroups.udp.mcast_port.
    jgroups.udp.mcast_port is checked internally by JGroups, and is used to override any XML-based configuration. If this parameter is set, two channels with non-shared transports cannot use different ports. The jboss.jgroups.udp.mcast_port property substitutes system properties in the default UDP channel configurations.
11.2.3.5. Transactions
Copiar enlace
The transaction manager configuration information has moved from conf/jboss-service.xml to deploy/transaction-service.xml.
11.2.3.6. Logging
Copiar enlace
  • The default conf/jboss-log4j.xml configuration now includes the thread name for log/server.log entries.
  • The new jboss.server.log.threshold system property can be used to control the log/server.log threshold. The default value is INFO.
  • server.log is appended, rather than truncated, after a server is restarted.
  • The following changes apply only to server/production/conf/jboss-log4j.xml:
    • the console logger has been commented out by default.
    • the async logger is enabled by default.
    • a cluster.log file has been added to store cluster output.
11.2.3.7. Security
Copiar enlace
Security-related configuration files are now found in the deploy/security directory: 
security/
   |-- security-jboss-beans.xml
   `-- security-policies-jboss-beans.xml
Copy to Clipboard Toggle word wrap
11.2.3.8. Enterprise JavaBeans
Copiar enlace
  • Enterprise JavaBean configuration information is now located in deployers/ejb3.deployer/META-INF/ejb3-deployers-jboss-beans.xml.
  • Java Persistence API configuration information is now located in deployers/ejb3.deployer/META-INF/jpa-deployers-jboss-beans.xml.

11.3. Admin Console
Copiar enlace

The first release of the JBoss Enterprise Application Platform Admin Console (admin-console) provides the following administrative features:
  • configuration information about the system on which the Enterprise Application Platform is running.
  • configuration information about the Service Binding Manager.
  • deploy, undeploy and update Enterprise Applications, including:
    • Java EE Enterprise Applications (EARs)
    • Web Applications (WARs)
    • Resource Adapters (RARs)
    • Enterprise JavaBean 2 and 3 (JARs)
  • persistent configuration changes for the following resources:
    • data sources
    • connection factories
    • JMS queues and topics (based on JBoss Messaging)
  • Control Operations:
    • execute scripts to perform tasks against a running instance of the application server
    • stop, start, and restart applications
    • view resource statistics
    • view resource metric information
The new admin-console provided with JBoss Enterprise Application Platform retains the JMX and web consoles. admin-console supports the production, all, web and default configurations out of the box. It has also been tested with standard server profile, but is not included in standard by default. To use admin-console in a standard profile, copy the admin-console.war from one of the supported server profiles.

Note

The Admin Console is not intended for use with the minimal configuration provided with the distribution. Custom configurations based on this configuration should not be used with the Admin Console, either.
When the server has been started, you can use the admin-console to perform administrative tasks for your application server. To use the admin-console, navigate to http://${hostname}:8080/admin-console.
Refer to the Administration Console User Guide for more information on the Admin Console.

11.4. Applications
Copiar enlace

JBoss Enterprise Application Platform 5 is a fully-compliant implementation of the Java Enterprise Edition 5 (Java EE 5) Platform Specification. Java EE 5 defines the metadata associations of the Java language which can be used to annotate application code and eliminate the need for deployment descriptors wherever possible. Default behavior is also defined with the ability to override as needed. This is known as configuration by exception.
Portable Java EE applications running on Enterprise Application Platform 4.x can be deployed to Enterprise Application Platform 5 without any changes. However, runtime-specific deployment information may be required when migrating from another vendor's application server to JBoss Enterprise Application Platform 5.
Enterprise Application Platform 5 users can take advantage of the simplified packaging and deployment rules defined in the Java EE 5 Platform Specification, such as no longer requiring an application.xml file in Enterprise Archives (EARs). Additionally, a default library directory (lib) in the root directory of an EAR makes the JARs available to all components packaged within the EAR. If an application.xml file is included, the library-directory element can be used to specify the location of the lib directory.
Enterprise Application Platform 5 also introduces a new deployable unit: the MCBeans archive, after JBoss Microcontainer, which typically takes the .beans or .deployer suffix. MCBeans archives package a POJO deployment in a JAR file with a META-INF/jboss-beans.xml descriptor. This format is common in Enterprise Application Platform deployers.
Application verification for all file types is enabled by default, and can be configured in the deployers/ear-deployer-jboss-beans.xml file, specifically: 
<!-- uncomment to disable xml validation
   <property name="useValidation">false</property -->
<!-- in case xml validation is disabled, it's also better to turn off schema validation
   <property name="useSchemaValidation">false</property -->
Copy to Clipboard Toggle word wrap
Enterprise JavaBean 2.0 archive verification remains the same between Enterprise Application Platform 4.x and Enterprise Application Platform 5. However, the properties that control verification have been moved from deploy/ejb-deployer.xml to deployers/ejb-deployer-jboss-beans.xml.
If an enterprise archive contains only an application client and refers to EJBs, you must also add the </ignore-dependency> element to the ejb-ref or ejb-local-ref definitions in the jboss-client.xml deployment descriptor. This informs the deployer to deploy the archive without resolving the referenced dependencies.

11.4.1. Classloading
Copiar enlace

The new ClassLoader is fully backwards compatible, with one exception that does not affect common use ( http://www.jboss.org/community/docs/DOC-12840 ). All classloading configurations from EAP 4.x will still work with the new implementation, and most default settings retain the behavior of the previous version.
The new ClassLoader shares many design and implementation details with the original UnifiedClassLoader, but makes the following improvements:
  • the classloader no longer depends upon JMX, so it can be used in any environment as a standalone.
  • it is much easier to implement your own classloader policy.
  • increased control over which classloaders your classloader delegates to.
  • increased control over which classes are visible to other classloaders.
  • hierarchical repositories have been replaced by domains, and can now extend beyond a single level.

Note

useJBossWebClassLoader="true" is not used in JBoss Enterprise Application Platform 5. All WAR classloaders in Enterprise Application Platform 5 are JBoss ClassLoader s, so the WarDeployer no longer handles the configuration details for web applications.
There are several methods available to change the classloading configuration of a WAR:
Remove the WarClassLoaderDeployer
The WarClassLoaderDeployer automatically implements the defined classloading rules for WARs. Each WAR is assigned a scoped classloading domain. Its classes are not visible to other applications or to any parent EAR, and where possible the WAR's classes are called first. To remove this behavior and make WAR classloading behave like other deployers, comment out the WarClassLoaderDeployer in deployers/jbossweb.deploy/META-INF/war-deployers-jboss-beans.xml.
Define classloading rules explicitly for the WAR
Add a WEB-INF/jboss-classloading.xml with the following content to your WAR. 
<?xml version="1.0" encoding="UTF-8"?>
<classloading xmlns="urn:jboss:classloading:1.0"
   name="mywar.war"
   domain="DefaultDomain"
   export-all="NON_EMPTY"
   import-all="true">
</classloading>
Copy to Clipboard Toggle word wrap
This lets you define how the WAR's classloader is constructed. In this case, the WAR's classloader has been placed in the DefaultDomain, which is shared with all other applications that do not define their own domain. import-all is enabled, which means the classloader will look at all other classes exported by other applications. export-all is set to expose all classes in our application to other classes.

11.4.2. EAR Scoping
Copiar enlace

You can control how class isolation between deployments behave with the isolated property in deployers/ear-deployer-jboss-beans.xml, as follows: 
<!-- A flag indicating if ear deployments should have their own scoped
   class loader to isolate theirclasses from other deployments. -->
   <property name="isolated">false</property>

JBoss Enterprise Application 5.2.0 is a minor release of JBoss Enterprise Application Platform 5.1.
An in-place upgrade from version 5.1.x to the latest version is available for customers who have installed the platform using RPM.

Important

This is a platform upgrade, not an assisted migration. The platform software will be updated to the latest version, however, you will have to update configuration files and verify the compatibility of your applications.
Follow Upgrade JBoss Enterprise Application Platform 5.1.x to the latest 5.1.x version using RPM to test and verify the entire process before applying it to a production system.

Upgrade JBoss Enterprise Application Platform 5.1.x to the latest 5.1.x version using RPM

Follow the overarching guidelines in this task to perform a non-production system pre-upgrade test. Complete this task before upgrading your production systems as a best practice platform upgrade task.
Once you are satisfied with the results collected as a result of the task guidelines, refer to Chapter 5, RPM Installation via Red Hat Network for upgrade commands and prerequisites for different operating systems.

Prerequisites

  • You have backed-up your JBoss Enterprise Application Platform data and configuration, and have verified you can restore the system to a known state.
  1. Stop all JBoss instances.
  2. Upgrade the 5.1 install to the latest update level.
  3. Locate and examine all .rpmnew files installed on your system by the upgrade process. 
    find $JBOSS_HOME -name *.rpmnew -ls
    Copy to Clipboard Toggle word wrap
    Identify the impact of these changes on your infrastructure and your applications.
    Compare the old versions of the new files, and make any necessary changes to the files before performing this upgrade on your production systems.
    During an RPM upgrade, RPM will install new versions of configuration files. These new versions will be saved with the extension .rpmnew, in order to preserve your existing configuration data. After the upgrade look for these files and compare them with your existing configuration files, making any necessary changes.
  4. Start all JBoss instances.
  5. Systematically test all applications and verify all applications work according to original specifications.
  6. Once satisfied with the results of your testing, roll the upgrade out to your production systems.

B.6. Setting the default JDK with the alternatives Utility
Copiar enlace

The alternatives utility serves for managing different software packages that provide the same functionality. Red Hat Enterprise Linux uses alternatives to ensure that only one Java Development Kit is set as the system default at one time.

Important

Installing a Java Development Kit from the Red Hat Network will normally result in an automatically configured system. However, if multiple JDKs are installed, it is possible that /usr/sbin/alternatives may contain conflicting configurations. Refer to Procedure B.5, “ Using alternatives to Set the Default JDK ” for syntax of the alternatives command.

Procedure B.5.  Using alternatives to Set the Default JDK

  1. Become the root user.

    The alternatives utility needs to be run with root privileges. Use the su command or other mechanism to gain these privileges.

  2. Set java.

    Run the following command: /usr/sbin/alternatives --config java
    Next, follow the on-screen directions to ensure that the correct version of java is selected. Table B.1, “java alternative commands” shows the relevant command settings for each of the different JDKs.
    Expand

    OpenJDK 1.6/usr/lib/jvm/jre-1.6.0-openjdk/bin/java
    Sun Microsystems JDK 1.6/usr/lib/jvm/jre-1.6.0-sun/bin/java

  3. Set javac.

    Enter this command: /usr/sbin/alternatives --config javac
    Follow the on-screen directions to ensure that the correct version of javac is selected. Table B.2, “javac alternative commands” shows the appropriate command settings for the different JDKs.

  4. Extra Step: Set java_sdk_1.6.0.

    The Sun Microsystems JDK 1.6 requires an additional command be run:
    /usr/sbin/alternatives --config java_sdk_1.6.0
    Follow the on-screen directions to ensure that the correct java_sdk is selected. It is /usr/lib/jvm/java-1.6.0-sun.

Appendix C.  Installing Apache Ant
Copiar enlace

The Java build tool Apache Ant is not required for the installation or normal operation of the JBoss Enterprise Application Platform. However, it is occasionally needed for some configuration tasks and also for building and deploying some applications.

Note

If running a development workstation, Apache Ant may already be installed.

Note

To learn more about Apache Ant, visit the project's website at http://ant.apache.org.

Procedure C.1.  Installing Apache Ant on Red Hat Enterprise Linux

  • Download and install Apache Ant on Red Hat Enterprise Linux by issuing this command: 
    [localhost]$ sudo yum install ant
    Copy to Clipboard Toggle word wrap

Procedure C.2.  Installing Apache Ant on Other Operating Systems

  1. Download and Extract

    Download the Apache Ant binary release from http://ant.apache.org/bindownload.cgi.
    Once it is downloaded, extract it into a preferred installation location, such as c:\Program Files\Apache\Ant\ or /opt/apache-ant-1.8/.

  2. Add the ANT_HOME Environmental Variable

    Next, create an environmental variable called ANT_HOME. This variable has to contain the path created in the previous step.
    • Do this on Red Hat Enterprise Linux/Hewlett-Packard HP-UX systems by adding the following line to the ~/.bash_profile file, substituting the path with that created above. 
      export ANT_HOME=/opt/apache-ant-1.7.1
      Copy to Clipboard Toggle word wrap
    • On Microsoft Windows Server, do this by click on the Start Menu and opening the Control Panel then selecting System -> Advanced -> Environment Variables. Create a new variable named ANT_HOME and configure it to point to the ant directory.

  3. Include bin in the PATH

    Next, append the ant installation's bin directory the PATH environmental variable.
    • On Red Hat Enterprise Linux/Hewlett-Packard HP-UX systems, add the following line to the ~/.bash_profile file after the one which sets the ANT_HOME variable: 
      export PATH=$PATH:$ANT_HOME/bin
      Copy to Clipboard Toggle word wrap
    • On Microsoft Windows Server, do this task by opening the Control Panel then selecting System -> Advanced -> Environment Variables->System Variables -> Path. Create a new variable, calling it ANT_HOME. Next, add a semicolon and %ANT_HOME%\bin to the end of the path value.
To test the Apache Ant installation, run ant -version from within a command line shell. The output should look similar to this: 
[localhost]$ ant -version
Apache Ant version 1.8 compiled on June 27 2008
