核心提示: 首先引入j2ee的包路径到ClassPath,已经安装Jbuilder的可以在它的安装路径lib目录下找到mail.jar,activation.jar,将这两个包加入系统的环境变量,那么即使不用JBuilder开发的话也可以使用了.程序:import java.io.*;import java.util.*;im

使用了.

     String email = "feng_lei@ecfounder.com;ladofwind@163.com";
     String content = "账号:123 密码:123 <br/>感谢您注册!<br/><a href='http://www.xxxx.com.cn' target='_blank'>www.xxxx.com.cn</a><br/>此致<br/>xxxx <br/>即日";

     }
   }


 }

编译通过后,在class文件的目录下建立一个文本文件MailServer.properties,
格式:
SmtpHost=smtp.163.com
User=user
Password=pwd
Sender=csdn@csdn.com
Subject=Hello


运行程序即可实现邮件发送!
