Thanks for the reply Chris. The Jboss WS is updated as mentioned in the Wiki and also a new user is registered with vignette. Even after this i am still getting the same error. How do one know what registration information need to be passed to a remote portlet. Would it be available in the wsdl file? Please let me know. Thanks once again.
