I am working with a sister company who has Websphere 6.x we use JBoss 4.0.5 EJB3. They are trying to create a MDB that will read messages off of a JMS queue depoyed in our JBoss AS.

They are having problems reading from my JMS queue, but I have no expereince with Websphere so I am not sure where the problem lies. I know I may need to ask this question in a Websphere forum, but:

1. Is it possible to have a MDB deployed on Websphere receive messages from a JMS queue on JBoss?
2. If so, what are my options for doing so?

I have found this documentation: http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingWebSphereMQSeriesWithJBossASPartI but it appears to deal with having a MDB deployed on JBoss that reads messages on a queue in Websphere. I need to do the opposite. I have come across the terms of "JCA" and "resource adapters" elsewhere in the documentation but I am not sure if this is what I am looking for. Any comments, or links to documentation would be greatly appreciated.
