1. 在struts-config.xml文件中添加验证框架的插件
<plug-in className="org.apache.struts.validator.ValidatorPlugIn"><set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/></plug-in>

2. 配置ApplicationResource.properties（eclipse默认struts的根目录）
将validator-rules.xml中 errors.required={0} is required. errors.minlength={0} can not be less than {1} characters. errors.maxlength={0} can not be greater than {1} characters. errors.invalid={0} is invalid. errors.byte={0} must be a byte. errors.short={0} must be a short. errors.integer={0} must be an integer. errors.long={0} must be a long. errors.float={0} must be a float. errors.double={0} must be a double. errors.date={0} is not a date. errors.range={0} is not in the range {1} through {2}. errors.creditcard={0} is an invalid credit card number. errors.email={0} is an invalid e-mail address.的信息copy到ApplicationResource.properties资源文件中

3. 创建Form
继承于ValidatorForm，不用reset 和 validate方法public class UserForm extends ValidatorForm { private String uname; private String upass; public String getUname() {       return uname; } public void setUname(String uname) {       this.uname = uname; } public String getUpass() {       return upass; } public void setUpass(String upass) {       this.upass = upass; }} 4. 设置struts-config.xml文件中的validate=false

5. 新建validation.xml文件，在validation.xml中配置验证信息
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE form-validation PUBLIC "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.0.1//EN" "validator_1_0_1.dtd" ><form-validation> <formset>              <form name="userForm">                 <field property="uname" depends="required">                                       <arg0 key="errors.uname"/>          </field>       </form> </formset></form-validation>

6. 实现客户端的javascript验证
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %><html>  <head> <title>My JSP 'index.jsp' starting page</title>  </head>  <body> <html:form action="login" >       用户名：<html:text property="uname"></html:text><br>       密  码：<html:text property="upass"></html:text><br>       <html:submit value="登录"></html:submit> </html:form> <html:javascript formName="userForm"/>  </body></html>
