ocpsoft/rewrite ? reverse-engineered prompt

Build me a Java URL rewriting library for servlet based web apps, something I can drop into an existing site to forward, redirect, and clean up URLs without much fuss.

I want it to work with Java EE and older servlet apps, and make it easy to define rewrite rules in code, like matching a path and forwarding it to a new page. Please include a simple way to register the configuration, either with an annotation or a service file, and make sure it can plug into common frameworks like CDI, Spring, JSF, JSP, and plain servlets.

It would be great if you also include a small demo or showcase app, plus tests, so I can see how it’s supposed to be used. If you need to check current docs or best practices while implementing it, go ahead and look them up online.
