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)
