To configure a queue or a topic, create a service.xml file. (myqueue-service.xml, for example) There are some examples of how to do it in jbossmq-destinations-service.xml in your deploy directory. In fact, you could put your own definitions in that file, but I like to create my own service files for them.

Here is an example from the jboss distribution:

 
  <mbean code="org.jboss.mq.server.jmx.Queue"
         name="jboss.mq.destination:service=Queue,name=ex">
    <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
  </mbean>

This queue's jndi name would be "queue/ex". You could look it up like that and use it directly (the connection factory is "ConnectionFactory") if you want. To link it to a MDB, add this in the enterprise beans section of your jboss.xml file:

      <message-driven>
         <ejb-name>YourMDB</ejb-name>
         <destination-jndi-name>queue/ex</destination-jndi-name>
      </message-driven>

It's pretty straightforward

//create a sender
Queue q = ( Queue ) ctx.lookup("queue/ex");
QueueSender sender = qSession.createSender(q);

I was having the same problem. I had deleted the hsqldb-ds.xml file from my
deploy folder. I just learnt that this file which configures access to the hypersonic database is used by jboss to keep jms related data.

Just add the hsqldb-ds.xml file to your deploy folder and try reinstalling your application. This sholud work
