SAF2
上struts.apache发现已经多出了一个Struts Action Framework 2的链接，看来ww2和strtuts的团队合并有了比较显著的进展
前期计划更名为strutsTi不知道现在为啥叫SAF2了?
（Struts Ti is in the Struts sandbox for continued development and possible eventual acceptance as a Struts subproject, and is NOT an official Struts sub-project and as such, is not ready for operational use.）
当然现在SAF2只是一个预发布版本，要研究的话官方推荐去WW2的网站http://www.opensymphony.com/webwork/
For SAF 2.0, the core goals are to repackage the codebase as an Apache Struts product and to provide migration resources for SAF 1 and WW 2 developers. A few legacy API elements will be removed, and a few new features will be added.
