[jboss-user] Form login authentication problem

[Joshua Zeckser]

Hello out there!

        I'm having a bit of a problem trying to use form login
authentication.
When I login from a jsp, I get a blank page, and the server shows the
exception:

14:54:40,940 ERROR [CoyoteAdapter] An exception or error occurred in the
container during the request processing
java.lang.ClassCastException: org.jnp.interfaces.NamingContext cannot be
cast to org.jboss.security.SubjectSecurityManager

Can someone give me an idea of what's going wrong?

Thanks,
