求助，我使用struts，为什么不能进行输入验证呀？

只要允许输入验证，程序就会出错。不知是我那里写错了。。
程序我是用jbuilder8写的，里面对struts的支持挺不错。

出错代码如下：

type Exception report
message Internal Server Error
description The server encountered an internal　error (Internal Server Error) that prevented it from fulfilling this request.
exception 
java.lang.IllegalArgumentException: Path reguser.asp does not start with a "/" character
 at org.apache.catalina.core.ApplicationContext.getRequestDispatcher(ApplicationContext.java:572)

<html:form action="/regUserAction" method="POST">
<p class="indent">

应该改为:

<html:form action="regUserAction">

你在定义action的时候，input的路径不对。
为什么是asp呢？
这个且不说吧，你在前面加一个"/"试试。
