To summarise, AFAIK, JBoss JCA currently only works inside the app server/servlet engine, it does not work standalone on the client side. I believe the JCA team are currently working on providing a standalone JCA implementation that will work on the client side, but I'm not sure of that. The JCA team on the JCA forum will know more about that than me. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221283#...
