Okay, now I've used the ProcessBuilder class for that
approach. Now I can find the destroy() method in the
Process class but it didn't help me. Here's how I
tried:
public class Main extends JFrame implements
ActionListener
Command com;
public Main()
super();
com=new Command(1,this); // this class
class implements ActionListener and handles the
actions happening in the Main class.
a_button.addActionListener(com);
/* from the Command class the ProcessBuilder is
der is started returning the instance proc of the
class Process.*/
public void windowClosing(WindowEvent evt)
com.proc.destryo(); //<------ does the API really have a typo in it?
System.exit(0);
public void window.....(WindowEvent evt){}....
}regards,
Jay
