这个DEMO供大家一起探讨学习Struts，因为工作太累，没精力给大家解释实现原理。如果看不懂，没关系。只是说明JSP基础还没有到火候，不要心急，回去强化下JSP+Servlet,基础扎实了，自然能够看懂我写的代码。这个DEMO借鉴了网上很多前人的经验，在此一并谢谢。

测试记录集由大家去Insert20多条吧。
因为这个论坛我不能上传附件，所以只好把代码一个一个的贴上来,我现在在一家小公司做事，工作中体会最深的是，对于应用软件项目来说，最重要的是客户的需求，使用什么技术不是最重要的，所以想和大家说一下，不要执迷于技术。对于一个软件项目，编写代码只占整个开发周期的20%，甚至更低。大部分的时间是在围绕客户需求做功能测试。能够写出上面的代码，对于一个程序员只能说只是达到了最基本的要求，对于一个程序员来说，最重要的是执着，耐心和锲而不舍。最后写上这些废话和大家共勉。如果有问题可以找我一起探讨，我的QQ：38065558。
