JAAS with JBOSS and Struts2

I have been able to authenticate a user using JAAS on Jboss 4.2. However here is my question? How do I access once the user is logged in what roles he/she has?

Here is my SessionLogin action, whihc implements the PrincipalAware interface, and i know from my debug lines this does get set. When i call isUserRole("Admin") it is showing false.

I thought implementing PrincipalAware will give me access to what got set with JAAS on JBoss

Can anyone help?

I agree. Here's the link:
