Shale

Shale is a cutting-edge web application framework that is primarily rooted in the concept of JavaServer Faces. It is designed as a collection of loosely linked services that can be assembled as needed to meet the specific requirements of any application. Shale goes above and beyond what is expected from a typical web application framework, providing features such as annotation-based functionality that lessens the need for extensive configuration, application event callbacks, a view technology called Clay, dialogues with conversation-scoped state, and support for remoting.

Shale also offers integration links for other frameworks, making it seamless to use when combinations of technologies are necessary in web development. One critical point to keep in mind is that Shale is only available under the Apache License Version 2.0.
