Well this explains a lot... Please note that this procedure applies for JBoss MQ. For JBoss Messaging substitute "jboss.messaging" for "jboss.mq" and "XAConnectionFactory?" for "UIL2XAConnectionFactory" Note: These instructions are for EJB 2.1 MDBs and not for EJB3 MDBs. The invoker proxy binding is no longer functional for ejb3.
