使用Struts碰到的问题

[langgui]

第一次用struts，写了个简单的例子，可是访问页面的时候却显示如下错误
type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

查看了下hello_jsp.java代码，发觉是使用Struts标签的时候出现的问题，可是标签配置经过反复查看没有任何的问题，这个例子是参照孙卫琴所写的那本精通struts上的第一个例子，请各位高手给予解答，小弟这里万分感激。

问题解决了，还是配置的错误，呵呵

在Struts里，有两个文件很重要：Web.xml和StrutsConfig.xml,学习时要特别注意
