request.getUserprincipal() and my custom Principal

["Hamidene, Anis Ben" <A....@dzbw.de>]

Hi,
 
I am using JBoss 3.2.1 with Tomcat 4.
I am developping a secure web-application based on JAAS. The problem is that
I want to use my own custom Principal.
I made the necessary changes in JBoss and EJBContext.getUserprincopal
delivers the right Implementation.
But when I call request.getUserprincipal() in my servlet, I get don´t !!
 
Why doesn´t tomcat use the defined custom Principal?
How to set this?
 
Please help as soon as possible !!!

Mit freundlichen Grüßen
