Depriving your application to run multiple times

Question

I created an application in java and I want it to run only once. If the application is already running, a messagebox should popup telling the user that the application is already running.

Any idea?

run the application as an instance from another class and keep the checking there — Vivek Aditya, Mar 12 '15 at 05:29

You can check the running programs pid names for an instance of the current program.
