Struts is no J2EE technology, rather it's a rather old and overly complicated application framework built on some J2EE components.
MVC is no J2EE technology either but an application architecture commonly used in J2EE applications.
I doubt there are many systems that use the entire J2EE platform, it's just too large.
Instead of trying to find a system using as many different things as possible you'd rather decide what to build and then decide the best technology to use based on that.

A simple JSP page with good architecture could cover a lot: MVC, regular java classes, servlet, and jsp. If you really want to use a lot of JSP, then a wiki would be kind of cool.

Also, a guestbook might not be too bad.
