Hi,
I have deployed WSRP4J on Tomcat 5.5.15. I am not sure about the version of
WSRP4J but I downloaded it on 31st Jan 2006. The portlets which comes bundled
along with it are working fine. But when I try to consume a new portlet I face
following exception. For deployment I am following the instructions provided at
URL http://portals.apache.org/wsrp4j/gettingstarted/config.html
Exception seen in producer (WSRP4J, tomcat) logs:

Can someone help me in resolving this. The portlet I am trying to deploy is as
per JSR168 specification.
