再问一个validator框架验证的问题？？（急！！！！）

[cz_2008]

我用validator来验证用户注册的信息，当运行时出现错误，无法验证，对于validator我是初学，不是很懂，代码编写我也不会，在一本书上摘了个现成的，我贴一下代码，麻烦各位高手多用两分钟时间帮我分析一下，非常感谢了！！

validation.xml:

validator-rules.xml文件太长，发不上来，烦高手指点一下，多谢！！

[zero1111]

validation.xml 放的地方对么？
org.apache.commons.validator.ValidatorException
这报异常了，看看你程序写的函数对么？

[cz_2008]

validator.xml,放的位置是对的，就是放在WEB-INF目录下的
org.apache.commons.validator.ValidatorException: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionErrors, javax.servlet.http.HttpServletRequest) 请问以上这段错误代码信息是什么意思？？
我对validator不是太懂，能具体说一下应用validator 的具体步骤，必须要用到那些文件！谢谢！！

[cz_2008]

自顶一下，上面的兄弟能否解释一下，希望各位高手帮兄弟个忙，具体的解释一下，我不是很懂！！
谢谢了~！！！！！！！！！！！！！
