I created the following
.desktop file under Fedora 24 using GNOME 3.
Exec=java -jar /home/zoltan/Bureau/Programs/JabRef-3.7-dev--snapshot--2016-11-08--master--fffad83.jar
When I opened it from the desktop, it launched the application, however when I copied it to
/usr/share/applications, the system couldn't recognise it and so I cannot launch it quickly. What can be the problem?
