How to start a background process from Swing application. In my swing application I start a background process thread by clicking a button. But When I close the application it also closes the thread. Any idea how to do it ?.

Are you setting the default close operation of the frame to EXIT_ON_CLOSE? That just calls System.exit() when you close your frame and kills the JVM. Same thing as if you attached a WindowListener to your frame and called System.exit(). If you want your frame to go away, but the thread to keep running, either hide (setVisible( false ) or HIDE_ON_CLOSE) or get rid of ( dispose() or DISPOSE_ON_CLOSE) your frame on closing, and wait for your thread to finish before calling System.exit(). If you have a reference to the thread, you can simply call thread.join() to do this. Important point - You have to put the code to wait for your thread to end and then call System.exit()... you can't skip this part because once you start up a GUI application in Java you must call System.exit() specifically because the AWT Event thread won't let the JVM die on its own.

I use dispose() method to close the frame. But the background process has to run forever. Is it possible to start the process in different JVM ?
