Did you try to post on a JTA user forum and end up on "Design of Clustering" instead? This is the second post I've seen on this forum this week asking obscure JTA questions complete unrelated to the forum topic. I'm wondering if there's a problem in the forum software. If you did deliberately post here, please use a user forum related to your question. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080019#...
