title: Opening a .jar in Ubuntu
body: <p>While making a game, i moved from programming in windows to ubuntu for better usability. that aside, when in windows, using <code>Desktop d = Desktop.getDesktop();</code> and using <code>d.open(new File("file dir.jar");</code> and it worked in windows. but, when using ubuntu, it opens the jar in an archive manager. so my question is, how would i open the .jar to be executed? Any help would be great! thanks in advance!</p>
  
  <p><strong>Edit:</strong> it may be possible i installed java wrong... but i did it the way i found on google. if that is the case, any correction would be great :D</p>
