Rampart throws NPE

Back
The services.xml file contents I had included appear wrong in the earlier
message. I have attached it in this mail.

Subject: Rampart throws NPE

I'm trying to call a simple service deployed in Axis2. I'm trying to enforce
that this service requires a SamlToken whenever it is called... If I invoke
this service with a soap request that doesn't have any security headers, I get
the below exception at the server. If I disenagage 'rampart' for the service,
there is no problem. Am I doing anything wrong in this scenario?

Thanks,
Murali
