Thanks for the pointer, it was very easy with windows but not so easy with 
linux.

The following worked with windows
                        try
                        {
                                Runtime rt = Runtime.getRuntime();
                                Process proc = rt.exec("app.exe");
                        } catch (Throwable t)
                        {
                                t.printStackTrace();
                        }
This would not work with linux
                        try
                        {
                                Runtime rt = Runtime.getRuntime();
                                Process proc = rt.exec("/home/jsg3/app");
                        } catch (Throwable t)
                        {
                                t.printStackTrace();
                        }
The permissions are set to allow Java to execute the file but it doesnt?
Even as root Java would not run the file?

Hi.
Not quite easy.
Take a look for a good example of runtime.exec at
www.javaworld.com
direct link  here:

I lose some hair until I found above article some months ago...
