用J2ME实现简单电子邮件发送功能[4]

    public MailThread(MailClient midlet)
    {
        this.midlet = midlet;
    }

public void run()
    {
        synchronized(midlet)
        {
            try
            {
                midlet.wait();
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
           
        }
        System.out.println("connecting to server.....");
        HttpConnection httpConn = null;
        DataOutputStream dos = null;
       
        try
        {
            httpConn = (HttpConnection)Connector.open("http://localhost:8088/mail/maildo");
            httpConn.setRequestMethod("POST");
            dos = new DataOutputStream(httpConn.openOutputStream());
            dos.writeUTF(midlet.getMessage().getTo());
            dos.writeUTF(midlet.getMessage().getSubject());
            dos.writeUTF(midlet.getMessage().getContent());
            dos.close();
            httpConn.close();
            System.out.println("end of sending mail");
        }
        catch(IOException e)
        {}
    }}

    在服务器端，我们要完成自己的servlet。他的任务比较简单就是接受客户端的数据然后通过JavaMail发送到指定的收件人那里。如果您对JavaMail还不熟悉请参考如下文章。这里直接给出servlet代码。
使用JavaMail实现收发电子邮件功能
使用Servlet发送电子邮件

package com.j2medev.servletmail;

import java.io.DataInputStream;
import java.io.IOException;
import java.util.Properties;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.*;
import java.net.*;

public class MailServlet extends HttpServlet
{
    private static String host;

    private static String from;

    public void init(ServletConfig config) throws ServletException
    {
        super.init(config);
        host = config.getInitParameter("host");
        from = config.getInitParameter("from");
        System.out.println(host + from);
    }

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException
    {

        doPost(request, response);
    }
