gwt-hibernate provides the basics to create a web application that uses GWT on the front end and Hibernate on the back end. It provides code generation templates and support classes that allow introspection, data binding, and validation of POJOs in the browser. Data-bound Form and Grid widgets are included.
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 also provides a dependency injection mechanism similar to Spring, which you can use to customize your controllers and views. 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.
