struts验证框架初学者问题

[crazyguo007]

我在Exadel Studio的Struts环境中做了一个简单的用户登录的Jsp页面，配置了一个与之对应的动态表单，想用struts自动验证框架验证用户名是否为空。
login.jsp代码如下：
<%@ page contentType="text/html;charset=GBK" language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html>
<html:javascript formName="LoginForm" />
<html:form action="LoginAction.do" method="post" onsubmit="return validateLoginForm(this)">
用户名：<html:text property="name" /> <p>
密码：<html:password property="pwd" /> <p>
<html:submit value="登陆"/>
</html:form>
<p>
<html:link page="/pages/regist.jsp">新用户注册</html:link>
</html:html>

struts-config.xml中动态表单的配置如下：
<form-bean dynamic="true" name="LoginForm" type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="name" type="java.lang.String"/>
<form-property name="pwd" type="java.lang.String"/>

validation.xml中的配置如下：
<formset>
<form name="LoginForm">
<field depends="required" property="name">
<msg key="msg.name.required" name="required"/>
</field>
</form>
</formset>

可是运行过程中老是弹出脚本错误'required'未定义，我用脚本调试器调试，发现错误在validator-rules.xml中的如下函数中：
<javascript><![CDATA[
function validateRequired(form) {
var bValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oRequired = new required(); //错误在这一行
........
}


请各位高手指点一下，问题可能出在哪儿？我想肯定不是validator-rules.xml中有错误，那时默认的验证规则中的javascript代码，那问题最可能在哪儿？
谢谢指点！

validator-rules.xml这个文件配置正确了吗？

[canghaisha]

validator-rules.xml要和你使用的struts版本一致 另外struts-config.xml中相应action中 要有 validator="true"

你控制台的错误就是我说的版本问题 他说在你的框架验证中找不到 对应的 required方法

[unrealwalker]

javascript的错？
把<html:javascript formName="LoginForm" />去了再看看

[chrisshang]

我很奇怪，为什么表单的数据一定要放在服务端进行验证呢，用JS在客户端不就可以了，这样还可以分担服务器的压力，虽然这样遵守MVC的架构，但我不喜欢这么用

[crazyguo007]

这个也是在客户端验证的

[crazyguo007]

非常感谢各位对我的帮助，我找到问题所在了，canghaisha提醒的对，是我的validator-rules.xml文件的版本不对，在Struts1.2中我却用了原来struts1.1版本的validator-rules.xml文件，希望大家以后不要犯我这种低级错误。
