webwork2.2到struts2的变化

While Struts 2 started with the code from WebWork 2.2.3, a few major changes have taken place that will impact the migration of a WebWork 2.2 application:

1、Deprecated methods and classes have been removed. This includes the XWork Inversion of Control (IoC) framework.

2、The tooltip library used by the xhtml theme was replaced by Dojo's tooltip component.

3、The rich text editor component that used the FCK editor was replaced by Dojo's rich text editor due to FCK's LGPL license

4、The date picker component was replaced by Dojo's date picker also due to LGPL license issues. Unfortunately, the Dojo date picker component has no support for internationalization unlike the WebWork component, and generally has less features overall.
