这是我的jsp页面
**************index.jsp**********
<%@ page language="java" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page isELIgnored="false"%>
<html>
<jsp:forward page="/index.do"></jsp:forward>
</html>
下面是出错信息:

我看了一切原因就是在jsp:forward上面,如果把它去了情况就没有了..
但究其根源在哪里,请各路高手赐教!
------解决方案--------------------
ShowAction.java:108行
有个空指针...
------解决方案--------------------
.do文件是一个网页后台程序，*.jsp或者struts的组件文件*.do ，不是一个文件,并没有一个真正的.do文件存在。
不能直接打开 ，你怎么赚到index.do上去了？
------解决方案--------------------
java.lang.NullPointerException
