I was able to start the jboss up and running and I was able to navigate the app also. Now if I bring down the node 1 of oracle rac the failover to next node (as mentioned in connection url) does not happens and jboss throws lots of exception. Now I bring the node 1 backup again and app seems to work fine. Looks like fail over is not working. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4260205#...
