[jboss-user] [JBoss Seam] - Classloading problem I think.
I am consistently getting long exceptions with the below as the root cause. I believe
this is from a classloading conflict, do you guys have any hints whatsovever as to how to
trouble shoot this? I'm puzzled, and the exception is not helpful.
