Java - running a few basic methods

I have an eclipse project regrouping two applications, I want to run the second application on my own or from the first, which I managed to do by simply calling the main method. The problem is that when I start the second application from the first, when I close this second application, it also closes the first application. Can I avoid this behavior and save the first application?

Thank.

The second application probably issues System.exitwhen closed. The only way to prevent this from dragging the calling application is to run it in a separate process (for example, via ProcessBuilder.startor Runtime.exec) or by catching and preventing it System.exitusing a special security manager.
