Mac OS El Capitan never opens .jar files

Question

Every time I try to save a.jar file for my programming course and it doesn't open, and yes I save the META.MF whit the correct path, I even stop making them on the Terminal and use Net Beans but same problem Error: Could not find or load main class a3t8e1.A3T8e1 maybe I need to download something else.

I search on the internet and download the jar launcher but nothing better.

this is the .jar unpacked

What is the difference in the first A3T8e1 file and the one in the folder? Also, are you following the answer provided here? http://stackoverflow.com/questions/9681876/how-to-create-a-jar-file-in-netbeans — OneCricketeer, Apr 06 '16 at 21:30

Please try to right click the .jar file and click the Get Info. Under the Open with, select the Jar Launcher.app. After that, try to reopen your related .jar file.
