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.util.*;
import javax.mail.*;
import javax.mail.internet.*;

}
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!
