I have an executable jar file which I'd like to be able to start from a shortcut on either the desktop or the start menu. I wrote a desktop file but I cannot get it to work no matter how I specify the Exec line. The file currently reads as
[Desktop Entry] Type=Application Name=Party Planner Exec=java -jar ~/Downloads/PartyPlanner.jar
When I click on the file on the desktop, absolutely nothing happens. The command in the Exec line works perfectly well when I enter it in the terminal. In fact, it works no matter what directory I'm in when I type it. I've tried replacing "java" and "~/Downloads/PartyPlanner.jar" in the desktop file with their respective absolute paths, but that doesn't help. I can't get this thing to work on either of my Lubuntu machines (one running 14.04 and the other 15.04).
What am I doing wrong? Is there some log file somewhere I should be looking at for error messages?
