使用javamail功能时，这是比较常见的一个异常。
原因是jar包版本不统一,解决方法如下:
删除Java EE 5 Libraries/javaee.jar/mail里的包有东西.
具体方法如下:
用rar打开X:/Program Files/MyEclipse 6.0/myeclipse/eclipse/plugins/com.genuitec.eclipse.j2eedt.core_6.0.1.zmyeclipse601200710/data/libraryset/EE_5/javaee.jar
,然后删除mail,一切就ok了.
如果上面的方法太复杂，那么在新建web工程时就直接选择javaee 4的那个版本的库
