    Have only 1 instance of a program running

    802349
      When my Java program is running and I execute the same program again, I'd rather have the GUI of the running program show up instead of spawning a 2nd process. Can anyone help me with that? Thank you very much!

          Why would you run it twice if you want to run it only once?

          You could for example create a .pid file in *NIX style, to see whether the program is already running or not.

            Thanks, but when someone kills the application, the file remains.

            Found a solution here:

            If anyone knows a better approach, please let me know.
