You should check out securityfilter
(http://securityfilter.sourceforge.net/) which does exactly what you
want. Yes, you will have to write your own "realm" type thing, but at
least you are not tying yourself to Tomcat (which isn't so bad, really).

Yeah, it wouldn't have been too bad. If you want to use something a
little more flexible than Tomcat's built-in security, you could look at
securityfilter. It gives you a little more freedom with the requirements
(for instance, you can do drive-by logins) and doesn't tie you to a
specific container.
