At the end of the stack trace, I found the following error.

Do you know where is this class coming from?

Where can I download JBoss XB 1.0.0.CR6?

Isn't that just the Jboss WS? It was installed when I got the error. I thought the problem is related to the jboss XML binding, not web services.

Sorry, my mistaken. I missed one of the instruction steps. After I got the jboss-xml-binding.jar, there are no exceptions when change the portlet provider.
