This example is a simple MDB which receives text messages from queue "testqueue" and prints it to System.out.
After download, unzip it and go to the "simplemdb" directory where you will find the EAR archive.
You will find all necessary bindings/configuration in the "ejb-jar.xml".
Copy "simplemdb.ear" to "standalone/deployments" of your JBoss distribution.
To test the example you need to send some text messages to queue "testqueue@router1". You can use the SwiftMQ example P2PSender to do that.
Switch to the router's distribution directory and there to "samples/router_network". From here run:
starter P2PSender smqp://localhost:4001 plainsocket@router1 testqueue@router1 100
It sends 100 messages to "testqueue@router1". Now have a look in JBoss' server.log file. You should see the printouts of the MDB for each message. Note that the messages are not printed in order because the messages are processed asynchronously from multiple instances.
