Hi all,
I get a NullPointerException in my GetRolesAction, hope somebody of you guys
can help me.
With my action I want to make the user roles of a cwertain project available
to the sitemap. The roles are stored in the Authentication Context.
All I want to do is read out the roles from the Authentication context and
put it in the map that is returned to the sitemap.
However I get a NullPointerException when retrieving the authentication
context.
I "followed" the exception to the Class AuthenticationContextProvider. I
guess the problem is that the ServiceManager is not initialized, but is
null.
How can I make my Code working? Do I have to call the service() method of
the AuthenticationContextProvider to set the serviceManager instance??
Thanks alot for bringing light into my darkness,
Regards,
Stephanie
