MyEclipse Send message appears exception in thread "main" Java.lang.noclassdeffounderror:com/sun/mail/util/lineinputstream

This problem occurs because the jar package version is not uniform and the workaround is as follows:
I imported the jar package in the project

Conflicts with MyEclipse's own jar

Delete the package in Java EE 5 Libraries/javaee.jar/mail there is something.

Specific operation:

Enter the installation directory for MyEclipse: I installed the myeclipse Blue 8.5 specific path as follows

E:\development_tools\myeclipse_8.5\install_d\common\plugins\com.genuitec.eclipse.j2eedt.core_8.5.0. Me201003231033\data\libraryset\ee_5

Find Javaee.jar, open and delete the Mail folder (you need to close the running MyEclipse, otherwise you cannot delete)
