It looks like I fixed that problem. I had to change the jndi name in calculator-ds.xml, because apparently it was conflicting with something else. Now there's only one issue left: 11:30:33,031 WARN [MessagingContainer] Could not find the queue destination-jndi-name=queue/azavia/testmdb | 11:30:33,031 WARN [MessagingContainer] destination not found: queue/azavia/testmdb reason: javax.naming.NameNotFoundException: queue/azavia/testmdb | 11:30:33,031 WARN [MessagingContainer] creating a new temporary destination: queue/azavia/testmdb | So how do you create a new message queue, without getting those warning messages?
