Hi,
As long as I know the specification for ejb2.0 ties the MDBs to JMS in this first release of MDBs, the specs also mention the intention to add support to other MOMs in the future but not in this first release.
I�m not sure(work with bea server) but I think that IBM Websphere has some kind of component that allow you to listen for MQ series destinations,
you should take a look at the documentation and you may get some help from Kyle Brown a Websphere specialist here on
Java Ranch foruns.
