Cause: the method in mail. Jar conflicts with the method in j2ee5.
Delete the default method:
D:/Program
Files/myeclipse6.5/myeclipse/Eclipse/plugins/COM. genuitec. Eclipse. j2eedt. core_6.4.100.zmyeclipse64100200805/data/libraryset/ee_5
In this path, you can see javaee. jar, use RAR to open the file, and then go to the javax folder to delete the mail and activation folders.
Download an activation. jar package
You can also use this mail to solve the problem when using the mail function.
