这个问题还是无解，哪位高手知道问题所在烦请告知一二，谢谢！

struts-config.xml的版本与实际使用的struts版本号不一致问题，见下面的链接，虽然我不是这个问题导致的


看了一篇文章说是编译class文件用得jdk版本与tomcat的jdk版本不一致导致的，我刚刚换了jdk，还是不行。

唉唉～我太菜了！！！！！！！
没配置web.xml! 如下配置即可，放到WEB-INF目录下


 
    xmlns:xsi=""
    xsi:schemaLocation=" /web-app_2_4.xsd"
    version="2.4">

这个例子不是step by step的，写书的同学是为了讲讲大体结构。
