1报错信息：

Exception in thread "main" java.lang.NoClassDefFoundError:com/sun/mail/util/LineInputStream

2 需要包mail.jar

3 如果是myeclipse引进的j2ee5包在安装目录： MyEclipse 6.5/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806/data/libraryset/EE_5下找到javaee.jar 打开后在j avax文件夹里,删除mail.jar和activation.jar

4 引进自己的mail.jar

总结：这是经过测试的代码如有疑问请联系qq: 263090670
