WebWork衍生出了Struts2，而不是Struts 1衍生了Struts2。因为Struts2是WebWork的升级，而不是一个全新的框架，因此稳定性、性能等各方面都有很好的保证：而且吸收了Struts 1和WebWork两者的优势，因此，是一个非常值得期待的框架。

-WebWork derived from the Struts2, Struts 1 and not derived from the Struts2. Because Struts2 WebWork is an upgrade rather than a new framework, the stability, performance and other areas have a very good assurance: it absorbs both Struts 1 and WebWork advantages, therefore, is a very worth the wait framework.
