ClassCastException with Axis Web Service

Question

I have a web service running on Tomcat 5.0 with the attached WSDL. I was able to deploy my BPEL process but got an ClassCastException error on invoking the operation getAccessPointsProtocols. Do you have any ideas? I am using version v2.0.10.
Thanks a lot..
