Java Security

I am very new to spring and acegi. Im getting the following error while trying to access my application after deploying. Im using Spring 2.0.1, acegi-security-1.0.0-RC2, eclipse 3.1 and the jetty server.

The error is as follows

HTTP ERROR: 500
No adapter for handler [springweb.controller.IndexController@1716fa0]: Does your handler implement a supported interface like Controller?
RequestURI=/index.htm
