首先我们看下，项目搭建文件布局，如下图：
（图一）
接下来看下，registerForm.jsp在浏览器上的执行页面效果图：
（图二）
附属源码如下：
1 <%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> 2 3 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 4 <html> 5 <head> 6 7 <title>My JSP 'index.jsp' starting page</title> 8 9 </head> 10 11 <body> 12 <form action="login" method="post"> 13 <table align="center" border="1"> 14 <caption><h2>用户登陆</h2></caption> 15 <tr><td align="right">用户名：</td><td><input type="text" name="username" /></td></tr> 16 <tr><td align="right">密码：</td><td><input type="password" name="password" /></td></tr> 17 <tr><td align="center" colspan="2"><input type="submit" value="提交"/> <input type="reset" value="重置"/></td></tr> 18 </table> 19 </form> 20 </body> 21 </html>
那么校验效果如何，接下来看下如下两站图的说明：
以下是图一中其他文件的源码：
1）RegisterAction.java
1 package com.abc.action; 2 import java.util.Date; 3 import com.opensymphony.xwork2.ActionSupport; 4 public class RegisterAction extends ActionSupport { 5 private String uname; 6 private String upassword; 7 private String reupassword; 8 private int uage; 9 private Date ubirth; 10 private String uemail; 11 public String getUname() { 12 return uname; 13 } 14 public void setUname(String uname) { 15 this.uname = uname; 16 } 17 public String getUpassword() { 18 return upassword; 19 } 20 public void setUpassword(String upassword) { 21 this.upassword = upassword; 22 } 23 public String getReupassword() { 24 return reupassword; 25 } 26 public void setReupassword(String reupassword) { 27 this.reupassword = reupassword; 28 } 29 public int getUage() { 30 return uage; 31 } 32 public void setUage(int uage) { 33 this.uage = uage; 34 } 35 public Date getUbirth() { 36 return ubirth; 37 } 38 public void setUbirth(Date ubirth) { 39 this.ubirth = ubirth; 40 } 41 public String getUemail() { 42 return uemail; 43 } 44 public void setUemail(String uemail) { 45 this.uemail = uemail; 46 } 47 public String execute() throws Exception{ 48 return SUCCESS; 49 } 50 }
2) RegisterAction-validation.xml

5)registerOk.jsp脚本很简单就不贴了，大体就是返回成功的提示文本可以随意发挥！
