How To Remove a Principal from HttpServletRequest

Dear Experts,

I'm having problems with people logging in then logout, and when try to login as a different user, the Principal name from request.getUserPrincipal().getName() still holds the previous user's name.

some say we can set Principal to null upon logout but I'm not sure how to go about with this since the interface of Principal only has access methods. Any help would be much appreciated.

What you do is invalidate the user session.  This call will do it:
HttpSession ses = request.getSession();
ses.invalidate();

We generally also clear the cookies.
