Flex与JAVA对数据的读 , 写 操作

数据库

CREATE TABLE `t_user` (
  `I_ID` int(11) NOT NULL AUTO_INCREMENT,
  `V_UserName` varchar(50) NOT NULL,
  `V_UserPassword` varchar(50) DEFAULT NULL,
  `D_UserBirthday` varchar(200) DEFAULT NULL,
  `I_UserDep` varchar(50) DEFAULT NULL,
  `V_UserEmail` varchar(200) DEFAULT NULL,
  `V_UserAddress` varchar(500) DEFAULT NULL,
  PRIMARY KEY (`I_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=gbk;

数据库连接类,查询数据,添加数据

package net.zhuoqun.connectDB;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;

public class DataServiceImpl {
	
	public static Connection getConnection() {
		Connection c = null;
		try {
			String driver = "com.mysql.jdbc.Driver";
			String url = "jdbc:mysql://localhost:3306/mytest";
			String username = "root";
			String password = "";
			Class.forName(driver);
			c = DriverManager.getConnection(url, username, password);
		} catch (Exception e) {
			System.out.println(e.getMessage());
		}
		return c;
	}

	// 查询用户
	public List getAllUser() throws SQLException {
		Connection c = getConnection();
		Statement st = c.createStatement();
		String sqlText = "select v_username,v_userpassword,d_userbirthday,v_useremail from t_user";
		ResultSet rs = st.executeQuery(sqlText);
		ArrayList userList = new ArrayList();
		while (rs.next()) {
			User temp = new User();
			temp.setUsername(rs.getString("v_username"));
			temp.setUserpassword(rs.getString("v_userpassword"));
			temp.setUserbirthday(rs.getString("d_userbirthday"));
			temp.setUseremail(rs.getString("v_useremail"));
			userList.add(temp);
		}
		return userList;
	}

	// 添加用户
	public void addUser(User user) throws SQLException {
		Connection c = getConnection();
		String sqlText = "insert into t_user(V_UserName,V_UserPassword,D_UserBirthday,I_UserDep,V_UserEmail,V_UserAddress) " 
						+"values(?,?,?,?,?,?)";
		try {
			PreparedStatement pstmt = c.prepareStatement(sqlText);
			pstmt.setString(1, user.getUsername());
			pstmt.setString(2, user.getUserpassword());
			pstmt.setString(3, "1983-05-16");
			pstmt.setString(4, user.getDep());
			pstmt.setString(5, user.getUseremail());
			pstmt.setString(6, user.getAddress());
			pstmt.execute();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

User类

package net.zhuoqun.connectDB;

import java.io.Serializable;
import java.util.Date;

public class User  implements Serializable{
    private String username;       	//姓名
    private String userpassword; 	//密码
    private String useremail;		//邮箱
    private String userbirthday;		//生日
    private String dep;				//部门
    private String address;			//地址

	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getUserpassword() {
		return userpassword;
	}
	public void setUserpassword(String userpassword) {
		this.userpassword = userpassword;
	}
	public String getUseremail() {
		return useremail;
	}
	public void setUseremail(String useremail) {
		this.useremail = useremail;
	}

	public String getUserbirthday() {
		return userbirthday;
	}
	public void setUserbirthday(String userbirthday) {
		this.userbirthday = userbirthday;
	}
	public String getDep() {
		return dep;
	}
	public void setDep(String dep) {
		this.dep = dep;
	}
	public String getAddress() {
		return address;
	}
	public void setAddress(String address) {
		this.address = address;
	}       
}

User.as

package com.gt.flex
{
	//与JAVA类中的  User.java 对应  包括 属性名 和 类型
        //如果为private的话,要想访问,就要写出对应的setter/getter方法
	[RemoteClass(alias="net.zhuoqun.connectDB.User")]
	public class User
	{
		public function User()
		{
		}
		public var username:String;
		public var userpassword:String;
		public var useremail:String;
		public var userbirthday:String
		public var dep:String;
		public var address:String;

	}
}

为什么flex发布以后index.html是404错误，找不到该页呢？可是我看发布在tomcat里的有这个文件呀。
