To facilitate the integration of 3rd-party JMS brokers as well as JBoss JMS brokers like JBossMQ and JBoss Messaging I have written a generic JMS JCA Resoure Adapter which should work in AS7. The project is hosted here where you can find documentation, source, and a download of the RA binary. It should be more straight-foward than using Sun's generic JMS JCA RA because you won't have to re-build it just so it will deploy.
