Dave, I totally agree with you about doing this kind of checking in an action class and I AM doing it there. However, the problem is that I still need a way to prevent a user from going to the jsp w/o first logging in.
Let's say the user logged in during a previous session and bookmarked the jsp. They can get back to it w/o having to login. I know that once they submit the form the action class will catch that they're not logged in and send them back to login page. But I'd rather catch it before then. I hate to have the user fill in a bunch of information, submit form and THEN get redirected to login. I'll look into JSTL. Are you saying it has "if-then-else" type of processing? Could you point me in the right direction for that and for the "check if object exists in session" issue? Also, I haven't used filters before. We just upgraded from Struts 1.0.2 so I'm pretty ignorant of all the features of newest version of Struts. Is this some kind of Struts filter or what is described here? http://java.sun.com/products/servlet/Filters.html Thanks again for your reply.

Otherwise you could always use a JSTL tag to check for a value in the appropriate session scope attribute key.
