I've been using Ubuntu for maybe ~1 week now, and I've downloaded a game, but my attempts at running it have so far been futile.

Game: http://7dfps.com/?action=games&id=228

I put the game's jar in this directory: /home/leafletpamhplet/games/, then try to run it by putting this in terminal:

cd /home/leafletpamhplet/games
java -jar boarding-party.jar

I then receive this error in turn after waiting for ~2 seconds.

leafletpamhplet@leafletpamhplet-HP-Pavilion-g6-Notebook-PC:~$ cd /home/leafletpamhplet/games
leafletpamhplet@leafletpamhplet-HP-Pavilion-g6-Notebook-PC:~/games$ java -jar boarding-party.jar

No idea what to do, or if this a problem with the game, or my java, although I havn't been able to run anything else with the same method.

Here's the full terminal text from when I tryed to run it.
