ejb-in-war: Deployment of a WAR Containing an EJB

Author: Paul Robinson Level: Intermediate Technologies: EJB, JSF, WAR Summary: Packages an EJB JAR in a WAR Target Product: EAP

What is it?

This example demonstrates the deployment of an EJB 3.1 bean bundled in a war archive for deployment to JBoss Enterprise Application Platform 6 or JBoss AS 7. The project also includes a set of Aquillian tests for the managed bean and EJB.

The example follows the common "Hello World" pattern. These are the steps that occur:

  1. A JSF page asks the user for their name.
  2. On clicking submit, the name is sent to a managed bean namde Greeter.
  3. On setting the name, the Greeter invokes the GreeterEJB, which was injected into the managed bean. Notice the field annotated with @EJB.
  4. The response from invoking the GreeterEJB is stored in a field message of the managed bean.
  5. The managed bean is annotated as @SessionScoped, so the same managed bean instance is used for the entire session. This ensures that the message is available when the page reloads and is displayed to the user.

System requirements

All you need to build this project is Java 6.0 (Java SDK 1.6) or better, Maven 3.0 or better.

The application this project produces is designed to be run on JBoss Enterprise Application Platform 6 or JBoss AS 7.

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start JBoss Enterprise Application Platform 6 or JBoss AS 7 with the Web Profile

  1. Open a command line and navigate to the root of the JBoss server directory.
  2. The following shows the command line to start the server with the web profile:

    For Linux:   JBOSS_HOME/bin/standalone.sh
    For Windows: JBOSS_HOME\bin\standalone.bat
    

Build and Deploy the Quickstart

NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.

  1. Make sure you have started the JBoss Server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. Type this command to build and deploy the archive:

    mvn clean package jboss-as:deploy
    
  4. This will deploy target/jboss-as-ejb-in-war.war to the running instance of the server.

Access the application

The application will be running at the following URL http://localhost:8080/jboss-as-ejb-in-war.

Undeploy the Archive

  1. Make sure you have started the JBoss Server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. When you are finished testing, type this command to undeploy the archive:

    mvn jboss-as:undeploy
    

Run the Arquillian Tests

This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.

NOTE: The following commands assume you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Run the Arquillian Tests for complete instructions and additional options.

  1. Make sure you have started the JBoss Server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. Type the following command to run the test goal with the following profile activated:

    mvn clean test -Parq-jbossas-remote 
    

Investigate the Console Output

JUnit will present you test report summary:

Tests run: 2, Failures: 0, Errors: 0, Skipped: 0

If you are interested in more details, check target/surefire-reports directory. You can check console output to verify that Arquillian has really used the real application server. Search for lines similar to the following ones in the server output log:

[timestamp] INFO  [org.jboss.as.server.deployment] (MSC service thread 1-7) JBAS015876: Starting deployment of "test.war"
...
[timestamp] INFO  [org.jboss.as.server] (management-handler-thread - 7) JBAS018559: Deployed "test.war"
...
[timestamp] INFO  [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015877: Stopped deployment test.war in 51ms
...
[timestamp] INFO  [org.jboss.as.server] (management-handler-thread - 5) JBAS018558: Undeployed "test.war"

Run the Quickstart in JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

    mvn dependency:sources
    mvn dependency:resolve -Dclassifier=javadoc
