I don't really know if this is a serious problem. Whenever I connect
to the database and start using it there is no problem. But when I
close my application JBoss immediately throws a connection error. I
think my xml descriptor has errors. Here is the StackTrace:

"22:26:55,140 ERROR [ServerThread] failed

Thank you very much for any help.
