Redhat Linux Class Loader Issue? (Non-Seam Issue)

[mdesignz]

This is not a Seam issue per se, but I would appreciate any comments if someone else has run into this.
I have a Seam 2.2.1.Final EAR application that runs fine under JBoss 5.1.0.GA and Mac OSX.  Deploying the same EAR using RHEL 6 and JBoss 5.1.0.GA, I get the following exception:

java.lang.ClassCastException: org.jboss.seam.webservice.SOAPRequestHandler cannot be cast to javax.xml.ws.handler.Handler

I'm guessing a class loader issue, but I'm not sure how to resolve it.
Thanks.

This is resolved.  My apologies for the noise.
Inclusion of jaxws-api in the EAR was the problem under RHEL 6 not Mac OSX.
