1、在struts-config.xml中添加如下代码

  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
  <set-property property="pathnames" value="/org/apache/struts/validator/validator-rules.xml,/WEB-INF/validations.xml"/>
  
  </plug-in>

2、在WEB-INF下建立validations.xml，假设验证的form名为inputForm，验证name,title,content不能为空，代码如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.3.0//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd">
<form-validation>
<formset>

<form name="inputForm">
<field property="name" depends="required">
<msg name="required" key="guest.inputForm.name"/>
</field>
<field property="title" depends="required">
<msg name="required" key="guest.inputForm.title"/>
</field>
<field property="content" depends="required">
<msg name="required" key="guest.inputForm.content"/>
</field>

</form>

</formset>

</form-validation>

3、设置显示信息的资源文件

guest.inputForm.content = content is null
guest.inputForm.name    = name is null
guest.inputForm.title   = title is null

4、在jsp文件的<body>前面添加<html:javascript formName="inputForm"/>，并修改<html:form action="/input" >，改为<html:form action="/input" onsubmit="return validateInputForm(this)">
