Dan Diephouse is looking for a Java Web Framework; there’s an excellent list in Brian McCallister’s answer. I’d add Echo2, which is cool if you’re not really looking for a Web framework, but rather for something to build applications that are tunneled through it (it’s an all JavaScript engine, so “View Source” will essentially show you nothing).
Personally, though, I believe I’d skip using a framework altogether, and go with JSPs and one or more hand-coded Servlets — I’ve not seen Java Web Frameworks yet that do not attempt to hide the Web from me.
Hey, if you evaluate frameworks based on how you “like” them instead of listing long-term business requirements, you deserve everything you get.
