BTW I think its worth saying, that in all the projects I've used JMS 
(which is most of them over the last 5 years), I think I use XA 
delivery less than 2% of the time. So for 98% of the time at least, I 
tend to use regular JMS with no transactions and just use the regular 
JMS acknowledge() or commit() mechanisms, which requires no J2EE 
transaction manager or special container hooks whatsoever.

So even if the JCA Container never supported J2EE transactions or 
didn't support them any where near as well as a full J2EE container, 
its still very, very useful IMHO.
