Have you configured the queues? How are you configuring them? Are you sure, they are being deployed before your application (containing the MDBs) is being deployed? You could try starting JBoss with just the queue/topic configurations in the deploy folder and without your application in the deploy folder. Then when JBoss has completely started, place your application in the deploy folder (for hot deployment). See if that works. This maybe related to the issue discussed at http://jira.jboss.com/jira/browse/EJBTHREE-1199 http://www.jboss.com/index.html?module=bb&op=viewtopic&t=130962 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4163448#...
