Web Resource Optimizer - wro4j

sI've uploaded to google code, a framework I've been working on recently, called wro4j (web resource optimizer for java). It allows you easily to merge, minimize & compress web resources (js, css), overwrite css url's in order to make it work even after merging. It is an easy customizable framework, you can easily extend it or to add some new features. It is not yet documentated very well, but I will dedicate some of my time for it very soon.

You can find the project on this page:
