I am having trouble integrating asp.net webservice
with wsrp consumer web part. I am able to configure
the wsrp webpart properly. Also I configured
TrustedWSRPProducers.config file properly. But i am
getting the following error when i try to connect

"The portlet server returned an error. It may not be
configured correctly. The details of the error message
have been added to the SharePoint log file on the
SharePoint server. Please contact your SharePoint
administrator to correct this problem."

If you guys have any sample webservice code written to
integrate with wsrp webpart please give me .
