Problem in Accessing Portal Web service

Hi Experts,

I have created Portal Webservice... I am trying to access that webservice..

I have created Client side by using that Webservice WSDL file.. here i got that web services methods.. then i configured httpservice proxy... finally i used that methods in AbstractPortal component.. I didnt get any error here...

I have Exported AccessingWeb service par...

I am getting the following error while running that component..

<b>com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: IOError while working with the message. Check the nested Exception..</b>

If anybody worked on portal webservice please help me to solve this problem..
