Problem with displaying remote protlets in consumer side.

Hi all,
I am new to portlets and wsrp portlets.I have created a producer application using weblogic workshop and make it as producer and add some portlets.
Next i created a consumer application in that i have created a 2 remote protlets and added to portal.I have created a SSO layer between producer and consumer.Finally if i access the consumer portal the remote portlets are not displayed properly.It shows the following error,
Error invoking portlet "Team Goals by Category"

The source of this error is:
