[jboss-user] [JBoss Seam] - Classloading problem I think.

[sjmenden]

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.
