非常感谢火龙果,老紫竹和sunyujia
首先要引mail.jar和activation.jar包
下载地址为:
javamail:http://java.sun.com/products/javamail/downloads/index.html
JAF:http://java.sun.com/javase/technologies/desktop/javabeans/jaf/downloads/index.html
下载后把.zip解压,然后把mail.jar和activation.jar复制到项目下的web-info/lib下
值得一说的是java ee 5和这个mail.jar和activation.jar有冲突
这个类在j2ee1.4下运行完全没有问题,但是如果在java ee 5下运行会报类找不到的错误,解决办法就是把myeclipse下的java ee 5的mail.jar和activation.jar干掉
进到
E:\Program Files\MyEclipse 6.5\myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.5.0.zmyeclipse650200806\data\libraryset\EE_5
这个路径里,可以看到javaee.jar,用rar把这个文件打开,然后进到javax文件夹里,删除mail.jar和activation.jar,然后再运行这个类,一切正常
