thanks for the replies. what i imagine. is a browser opening when i want to launch what i wrote. but maybe thats just a bit too far out of my league yet im very new a programming. so i still have a "hard time" understanding how it works in reality
followed your first advice, i got my file with a java icon on it. i double click it, and nothing happens? only possible thing that might be wrong, that i can see is maybe the java program i use to launch isent the right? i use "java platform se binary" you got any suggestions?
actually something does happen really fast. a cmd opens and closes really fast. captured what it said with a screen shot : Error: could not find or load main class c:\users\nico\desktop\var1.jar
btw thanks for your reply. exporting it, so obvious. i just thought i saved it, and tryed to run it as the saved file from eclipse.
