Hi peter, thanks for your reply. I was meaning, is there a way to trigger an Action when a connection is not reachable (f.e. oracle listener just shut down) ? from what I can understand, I can discover a "broken" connection only polling the DB with a running thread.....maybe is there something built-in which does this ? thanks marco View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4216872#...
