helloworld-mdb: Helloword Using an MDB (Message-Driven Bean)

Author: Serge Pagop

What is it?

This example demonstrates the use of JMS 1.1 and EJB 3.1 Message-Driven Bean in JBoss AS 7.1.0.

This project creates a queue named HELLOWORLDMDBQueue which is bound in JNDI as java:/queue/HELLOWORLDMDBQueue.

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 Full 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 full profile:

    For Linux:   JBOSS_HOME/bin/standalone.sh -c standalone-full.xml
    For Windows: JBOSS_HOME\bin\standalone.bat -c standalone-full.xml
    

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-helloworld-mdb.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-helloworld-mdb/.

Investigate the Server Console Output

Look at the JBoss Application Server console or Server log and you should see log messages like the following:

15:42:35,453 INFO  [class org.jboss.as.quickstarts.mdb.HelloWorldMDB] (Thread-47 (group:HornetQ-client-global-threads-1267410030)) Received Message: This is message 1
15:42:35,455 INFO  [class org.jboss.as.quickstarts.mdb.HelloWorldMDB] (Thread-46 (group:HornetQ-client-global-threads-1267410030)) Received Message: This is message 2
15:42:35,457 INFO  [class org.jboss.as.quickstarts.mdb.HelloWorldMDB] (Thread-50 (group:HornetQ-client-global-threads-1267410030)) Received Message: This is message 3
15:42:35,478 INFO  [class org.jboss.as.quickstarts.mdb.HelloWorldMDB] (Thread-53 (group:HornetQ-client-global-threads-1267410030)) Received Message: This is message 5
15:42:35,481 INFO  [class org.jboss.as.quickstarts.mdb.HelloWorldMDB] (Thread-52 (group:HornetQ-client-global-threads-1267410030)) Received Message: This is message 4

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 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
