Thanks very much! This was exactly my problem! In case you are wondering about it failing on the 3rd deployment instead of the 2nd... it turns out I had given the 2nd app a different identifier already, but the 3rd was a duplicate of the 1st, and I was always deploying in the same order. I was wondering why it wasn't failing on the 2nd deployment. Thanks so much for your help! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024817#...
