Introduction to SiteMesh

In my experience, I've been able to easily solve these problems cleanly, easily, and elegantly using the open source servlet filter SiteMesh, which is hosted on java.net. Instead of requiring a new templating language, XSLT, or "porting" your pages to a new system, using SiteMesh often allows you to dramatically simplify your pages while still using ordinary HTML, JSP, servlets (including Struts), and other familiar technologies.
