j2me组合j2ee实现用户登陆功能-2【转】

服务器代码:
LoginServlet:
package com;

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.OutputStream;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/** *//*******************************************************************************

@SuppressWarnings("serial")
public class LoginServlet extends HttpServlet
{

????public void doGet(HttpServletRequest request, HttpServletResponse response)
????????????throws ServletException, IOException
????{
????????this.doPost(request, response);
???? }

????public void doPost(HttpServletRequest request, HttpServletResponse response)
????????????throws ServletException, IOException
????{
????????// 得到客户端传入的数据(用户名和密码)
???????? String username = request.getParameter("username");
???????? String password = request.getParameter("password");
????????// 构建输出流
???????? ByteArrayOutputStream baos = new ByteArrayOutputStream();
???????? DataOutputStream dos = new DataOutputStream(baos);
????????// 逻辑操作(这里写你的逻辑判断)
????????if ("zdw".equals(username) && "admin".equals(password))
????????{
????????????// 响应数据
???????????? dos.writeUTF("true");
???????? } else
????????{
????????????// 响应数据
???????????? dos.writeUTF("false");
???????? }
????????//
????????byte[] data = baos.toByteArray();
????????// 设置服务器响应参数
???????? response.setStatus(HttpServletResponse.SC_OK);
???????? response.setContentLength(data.length);
???????? response.setContentType("application/octet-stream");
???????? OutputStream os = response.getOutputStream();
???????? os.write(data);
???????? os.close();
???? }

}
