TokenService Deployment problem - Unable to initialize TrustBindingSkeleton

Hello, I have been playing with Higgins products for about three month and doing some research about what meta-identity systems and user-centric can offer.

In these time I have tryed to deploy many of your solutions with often a high grade of satisfaction but now I'm unable to deploy the basic TokenService STS. Mainly the problem happens when I try to retrieve claims from the managed card generated by STS using the Windows Cardspace selector. When the selector and STS start the token retrieve protocol I recieve a nastly exception in Tomcat console:

Main problem its that the class its on WEB-INF/classes directory so have to be visible from the context. Mainly the data flow I use its: TokenService(cardGeneration) > RelyingPartyDemoApp(login) > Windows Cardspace (claim retrieve).

Any idea?

Thank you in advance.
