Sorry, i meant jboss.xml and not ejb-jar.xml. Anyways, you don't seem to be using xml configurations for your beans. Which version of JBoss are you using? Also, are you using EJB3 or EJB2.x? Can you post your MDB (if it is configured through annotations)? Are you using the JBoss "default" server or the "all" server?
