J2ee5与javamail的冲突

转载：http://www.cnblogs.com/arix04/archive/2009/06/29/1513404.html

J2ee5自带的activation，mail的jar包会与javamail的jar产生冲突，

解决方法是找到myeclipse里面的javaee.jar，打开这个Jar包找到mail与activation文件夹目录将其删除，刷新工程后即可。

javaee.jar在我本机的路径如下：

D:\eclipse\myeclipse\eclipse\plugins\com.genuitec.eclipse.j2eedt.core_6.0.1.zmyeclipse601200710\data\libraryset\EE_5
