javamail,java发email,发邮件,jaf,activation,j2ee5冲突问题解决

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 发邮件的类
