Close external program

Question

Hello, I've created this simple chat program with swing. And Ive also made this external server which handels the klients(users). Ive turned this server program into an .exe file. In my chat program I can start this server with:
Runtime runtime = Runtime.getRuntime();
Process p = runtime.exec("c:\\searchwayToWereMyServerIs.exe");And that works fine.
But now I wanna close the server also. Ive tryed to use the p.destroy(); command but it doesnt work. Does anyone know an way(another way) to end this external server?

Answer 1

I mean that nothing happens. Its still working after Ive used that command.
Im my chat program where I start it I use menues and therefore actionlisteners to start the server, this is how it looks:
       serverAction.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent arg0) {
                    try {
                         process = Runtime.getRuntime().exec(serverPath); // start a process
                    catch (IOException e) {
                         display.setText("Could not start server");
        });And this is the listener for the close server:
        closeServerAction.addActionListener(new ActionListener(){
               public void actionPerformed(ActionEvent arg0) {
                    process.destroy();
          });Is it wrong to do it like that?
