是你的password设置了minlength验证
我刚发现这个问题。
还不知道如何解决。

添加validator框架主要注意以下几个步骤：
  一、检查是否有validator-rules.xml(这个直接拷贝就是，基本上不需要更改)、validation.xml(自己配置form需要验证的字段)两个文件，并将两个文件放到WEB-INF下面
  二、在添加form时，Form Impl 选择的类型是Dynamic FormBean, Dynamic Type选择的是org.apache.struts.validator.DynaValidatorForm，如果你选择的是org.apache.struts.action.DynaActionForm则不能验证。(这点最重要，需要检查清楚)
  三、在validation.xml文件配置验证选项.看了你的这个配置
<form-bean name="CheckForm" type="struts.sample.cap5.sample1.form.CheckForm" />
你这个地方的formbean type错了，还有，如果你的这个form没有一个字段，这也是错误的，你后面验证这个form的字段，字段都没有，怎么验证，搞不懂你。。在好好检查一下。
<form name="CheckForm">
<field property="userName" depends="required,mask">
<arg0 key="userName" />
<var>
<var-name>mask</var-name>
<var-value>${numericchar}</var-value>
</var>
</field>

其他我没看哈,不过你想使用这个框架如果是后台验证的话就得加validate="true"
但是你如果是想进行页面间的验证的话,页面就少了一句话哈...得加上,找个例子看看,这个基本都是死的

动态验证在jsp页
要添加<html:javascript formName="bean的name例 loginForm" />form中 <html:form action="/login" onsubmit="return validateLoginForm(this)">

CheckForm 中重写validate()方法
public ActionErrors validate(ActionMapping mapping HttpServletRequest request)
{
return super(mapping,request);
}

struts-config.xml中：input="/ee.jsp"改成input="/user.jsp"

调试易
