I think you can get the user name by getting the Principal object from request and then getting the name from it like

String userName = request.getUserPrincipal().getName();

I want to use  tomcat user authentication in my application. for that i am using 
JDBCRealm.I have set the security constraint in the web.xml. So when  a request for 
the restricted page comes a login page comes.
But the problem is that it is submitting to the j_security_check and the textboxes are 
named j_username and j_password respectivley.I want session mangemant in my 
application. For that I need the login name of the person on my each page. How can I 
pass the username from login page to my page. is it possible to maintain session using 
tomcat user authentication or should i go for my own authentication and session 
management.

Plz help me Thanks in advance Amit Varshney
