Summary: The helloworld-mdb
quickstart uses JMS and EJB Message-Driven Bean (MDB) to create and deploy JMS topic and queue resources in WildFly.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/
The helloworld-mdb
quickstart demonstrates the use of JMS and EJB Message-Driven Bean in WildFly Application Server.
This project creates two JMS resources:
HELLOWORLDMDBQueue
bound in JNDI as java:/queue/HELLOWORLDMDBQueue
HELLOWORLDMDBTopic
bound in JNDI as java:/topic/HELLOWORLDMDBTopic
The application this project produces is designed to be run on WildFly Application Server 11 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.
For Linux: WILDFLY_HOME/bin/standalone.sh -c standalone-full.xml
For Windows: WILDFLY_HOME\bin\standalone.bat -c standalone-full.xml
mvn clean install wildfly:deploy
This will deploy target/helloworld-mdb.war
to the running instance of the server. Look at the WildFly console or Server log and you should see log messages corresponding to the deployment of the message-driven beans and the JMS destinations:
...
INFO [org.wildfly.extension.messaging-activemq] (MSC service thread 1-4) WFLYMSGAMQ0002: Bound messaging object to jndi name java:/queue/HELLOWORLDMDBQueue

....

INFO [org.jboss.as.ejb3] (MSC service thread 1-6) WFLYEJB0042: Started message driven bean 'HelloWorldQTopicMDB' with 'activemq-ra.rar' resource adapter
The application will be running at the following URL: http://localhost:8080/helloworld-mdb/ and will send some messages to the queue.
To send messages to the topic, use the following URL: http://localhost:8080/helloworld-mdb/HelloWorldMDBServletClient?topic
Look at the WildFly console or Server log and you should see log messages like the following:
INFO [class org.jboss.as.quickstarts.mdb.HelloWorldQueueMDB] (Thread-9 (ActiveMQ-client-global-threads-1189700957)) Received Message from queue: This is message 5

mvn wildfly:undeploy
You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.
NOTE: Within JBoss Developer Studio, be sure to define a server runtime environment that uses the standalone-full.xml
configuration file.
If you want to debug the source code of any library in the project, run the following command to pull the source into your local repository. The IDE should then detect it.
mvn dependency:sources
