GWTruts is an easy-to-use framework for using GWT with MVC and dependecy injection. It virtually divides a GWT module into view, controller, and validation sections similar to traditional MVC Web frameworks like Apache Struts.

It provides a page decorator where you can define mappings between a URL and a group of controllers/views and sections of the HTML files.
