Help needed with Realm authorization and Authentication

[sheidaei]

Dear All

I'm somehow new to weblogic workshop, and i want to have a role based
security for a project.
I used XML based security in web.xml and in web-config.xml . Now i have
a problem, regarding to my project, i want for example, if role A was
logged in, to show him A in one pages of pageflow (for example
index.jsp) and if another role was logged in, not to show him the A.

I mean I want to have access to Roles in the pageFlow, and by knowing
which Role change the sequence of pageflow, do you ever reach this
problem ? any suggestions ?

I think there must be an API for accessing the realm security for
Weblogic.
