Apache Shale

Shale is a modern web application framework, fundamentally based on JavaServer Faces. Architecturally, Shale is a set of loosely coupled services that can be combined as needed to meet particular application requirements. Shale provides additional functionality such as application event callbacks, dialogs with conversation-scoped state, a view technology called Clay, annotation-based functionality to reduce configuration requirements and support for remoting. Shale also provides integration links for other frameworks, to ease development when combinations of technologies are required.

Features

• View Controller - Convenient mechanism to associate a "backing" Java class with each JavaServer Faces view in an application, with predefined event handers for events significant to an application developer.
• Dialog Manager - Mechanism to define a "conversation" with a user that requires multiple HTTP requests to implement, modeled as a state diagram.
• Application Manager - Traditional application wide front controller features that should be applied to every request.
• Validation - Integration with the Jakarta Commons Validator Framework, supporting both client side and server side validations based on a single set of configured validation rules.
• Remoting - Server side support for applications that employ AJAX (Asynchronous JavaScript and XML) style interactions.
• Spring Integration - Integration with the Spring Framework, allowing the use of Spring's dependency injection framework to create JavaServer Faces managed beans.
• Clay - An alternative to JSP where you define views in pure HTML, in a fashion similar to Tapestry and Facelets. An innovative sub-framework for supporting the configuration of reusable subtrees of JavaServer Faces components for customizable reuse.
• Test Framework - Set of mock objects and JUnit test case base classes suitable for testing both the framework classes themselves, as well as application components built on top of the framework.
• Tiger Extensions - Optional add-on library that adds additional ease-of-use features for Shale applications that run on Java Standard Edition 5 (popularly known by its code name during development, "tiger").
