Shale Framework
　　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.
Shale Features
　　The major features of the Shale Framework are described in the       following detail sections:

• 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").
  

Shale Foundations
Shale is based on (and requires a runtime environment that         supports) the following foundation technologies:

• Java Runtime Environment (JRE) 1.4 or later.
  
• Servlet API 2.4 or later.
  
• JavaServer Pages 2.0 or later.
  
• JavaServer Faces 1.1 or later.
  
• JSP Standard Tag Library (JSTL) 1.1 or later.
  
• Apache Commons BeanUtils 1.7 or later.
  
• Apache Commons Chain 1.1 or later.
  
• Apache Commons Digester 1.8 or later.
  
• Apache Commons Logging 1.1 or later.
  

Various optional Shale components have dependencies on the following         additional runtime technologies:

• Apache Commons Validator 1.3.1 or later.
  
• Apache Commons SCXML 0.6 or later.
  
• Spring Framework 1.2.8 or later.
  
• Tiles 2 (the stand-alone version of Tiles, currently in the Struts Sandbox).
  
• Cargo
  
• jMock
  

If you wish to work on Shale itself, you will require the following         additional resources:

• Java Development Kit (JDK) 1.4 or later.  (JDK 1.5 is required for Shale Tiger.)
  
• Apache Maven 2.0.4 or later.
  

我非常期待这个框架，虽然现在Shale不是很流行，但是毕竟它是Struts的“子框架，可以大量的重构Struts代码，最主要是它的基于JSF框架的，Sun大力推行的框架。不错不错！
