Returning "read only" would be the most optimal thing to do. You then don't record the prepare in the journal. However, once you do that the non-peristent message should be removed from memory or anywhere else you reference it. If you return "read only" you won't get the commit/rollback notification. That obviously means non-persistent messages won't get redelivered once they've tried to be prepared in a 2PC transaction, even if the eventual outcome of the transaction is a rollback. That is perfectly spec compliant though since there's no guarantee the message would get delivered in the first place, let alone redelivered after a rollback. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175047#...
