任何结果都是由简单的实践得出的，当然我下面的介绍也是模仿那些大牛们，下面WebWork的介绍也是从古老而经典的HelloWorld开始。
在今天，各种各样的框架让我们眼花缭乱，但我始终坚信一点：“存在就是合理的”（黑格尔之哲学），各种框架利弊优劣等不是本篇之目的。
首先表述一下我做这个HelloWorld的机器环境
JDK5
Eclipse 3.3.1
mysql 5.0.45-community-nt

jar包：
commons-fileupload.jar - Apache Commons Fil Upload version 1.0
commons-logging.jar - Apache Commons Logging version ???
cos-multipart.jar - Cos Multipart File Upload version ???
mail.jar - Mail API version ???
ognl.jar - OGNL version 2.6.5
oscore.jar - OSCore version 2.2.4
pell-multipart.jar - Pell Multipart File Upload version ???
velocity-dep.jar - Velocity (plus dependencies) version 1.3.1
xwork.jar - XWork version 1.0.5

打开Eclipse建一个Hello的web工程

先写一个User.java 即MVC中的M：

[color=darkred]

package com.test;

/**
*
* @author yiqiao
*/
public class User {
private String userName;
private String userPwd;

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getUserPwd() {
return userPwd;
}

public void setUserPwd(String userPwd) {
this.userPwd = userPwd;
}

}

在看一下MVC中的C：
[color=darkred]

package com.test;

import com.opensymphony.xwork.Action;

/**
*
* @author yiqiao
*/
public class LoginAction implements Action {
private User user = new User();

public String execute() throws Exception {
if (user.getUserName().equals("yiqiao"))
return this.SUCCESS;
else
return this.ERROR;
}

public User getUser() {
return user;
}

}

页面3个：
index.jsp
