How to remember loginner's info to use?

[dudoes]

I have successfully used FORM to auth loginner throgh JAAS.

But I hope I can catch the loginner's information, for instance, userId, to use by other .jsp in the same Sesson, because login.jsp 's ACTION = "j_security_check",

How can I capture the useId after authed successfully?
because I want to get other informations of that user from users DB through userId.

You could get the user name by request.getUserPrincipal()
