Launch External Jar through Java Application

Question

Currently, I have an Java Standalone Swing Application.

Now, when user clicks on the button in the Swing Application, I would like to launch another Java Application (Say : calculator.jar)

May I know what is the portable way to do so? So that it will work in multiple OS?

Please clarify: is that "other jar" in the classpath, do you want to launch it in the same VM or in the separate? — Juriy, May 12 '10 at 18:04

Either use Desktop#open() or just put it in classpath and invoke its main().

You should be able to just use java to run the jar.

Runtime.getRuntime().exec("java -jar calc.jar");
