Thanks Erel, now create the directori build in the tempjars folder, I wanted to ask you 2 questions; the first is that when creating the build in the mac it creates a file called run_command, clicking on it starts the program from the terminal, is it not possible to start the program directly ?. the second question is that it is in windows where it creates the bulid directori and an executable run and im mac where it creates a run_command file but I know where to look for the jar file I created.
regards
