[jboss-user] [JBoss Seam] - Very strange exception

[gus888]

Hi all,
I don't know what I did wrong recently. After I deployed codes to a running jboss server, I always got the exception shown below when I begin to run it, exception that I shut down server and restart. This is very boring exception. Every time when I modify codes and deploy it to server, I always have to shut down server and restart it. Can anybody give me some advice? Thank you in advance.
