what is the Struts2.0?
许多朋友可能对于Struts 2.0与WebWork关系还搞不清楚。下面是Apache的Struts官网中的一段话：
Apache Struts 2 was originally known as WebWork 2. After working independently for several years, the WebWork and Struts communities joined forces to create Struts2.
原文大意为： Apache Struts 2即是之前大家所熟知的WebWork 2。在经历了几年的各自发展后，WebWork和Struts社区决定合二为一，也即是Struts 2。
