I am using frame not applet in my applicatin.
I am using java-code as:-

public class tryfocus1 extends JFrame implements ActionListener
{
JButton open,close;
JPanel jp=new JPanel();
Process child;
public tryfocus1()
{
 super("Main Window");
 getContentPane().setLayout(new BorderLayout());
 
 open=new JButton("Open netscape");
 open.setActionCommand("open");
 open.addActionListener(this);
  jp.add(open);
   
 close=new JButton("Close process");
 close.setActionCommand("close");
 close.addActionListener(this);
  jp.add(close);

  getContentPane().add(jp,BorderLayout.CENTER);

  setSize(800,600);
  setVisible(true);
  addWindowListener(new r1());
}

public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("open"))
{
  System.out.println("Clicked on open");
  String s="file:///c:/javascript/1.htm";
   try{
   child=Runtime.getRuntime().exec("cmd /c start netscp6 "+s);  // working
in minimize form.
   System.out.println("Netscape running process "+child);
//printing process name
   }catch(Exception e1){}    
 }
if(e.getActionCommand().equals("close"))
{
  System.out.println("Child: "+child);
//printing same process name
try{
child.destroy();
// not doing anything
}catch(Exception c){}              
 }
}

public static void main(String args[])
{
 tryfocus1 s=new tryfocus1();
}
}

class r1 extends WindowAdapter
{
    public void windowClosing(WindowEvent r)
  {
           System.exit(0);
   }
}

Is there any way to run code successfully.
Can I move control to other processes running using java-code.

I don't want to prompt user that close the browser.It should get closed
automatically when I am closing my frame-application.

Is there is any way to destroye that process which has been started in frame-
application.

Using processname.destroy() it is not working.

How can I achieve this?

Process.destroy() not working.
