Subject Re: Problems with Jboss and EJB 3.0 using ActiveMQ
Date Fri, 06 Jul 2007 13:58:46 GMT
We attempted this as well, but it seemed the JCA adapter for AMQ was
implemented to throw on all the new JCA 1.5 calls.  So the MDB deployer
would immediately fail when it tried to setup the listeners.  Looking at the
jca source from AMQ (was a pre 5.0 snapshot from a month or two ago) the
methods were all there, but the body of the methods were just "throw new
RuntimeException("Not implemetned")" or something like that.

This should work if you use the jboss jca implementation and just manually
bind the connection factories to
(plus the Queue and Topic versions of each)

But be warned that with the jboss jca adapter, you'll get N connections to
AMQ per mdb (N being up to the size of instance pool).  Which in our system
meant that each jboss server was holding 110 connections before any
activity, then spiked to 400-500 connections under load (using jboss
defaults form MDB3)
