In this post you will learn how to match complex urls with regular expressions and PrettyFaces in JSF2 Web Applications.
As Lincoln Baxter posted recently in the PrettyFaces-Blog, the upcomming PrettyFaces 2.0.3 will include support for JSF-Validators within PrettyFaces, allowing to reuse the already existing Validators infrastructure for Pretty URL Mapping (SEO Stuff etc.) Nice one Lincoln!
