To close JFrame over a JDialog

Question

Hi,
I am facing a slight problem. Say I have a code like under
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class abc extends JDialog implements ActionListener
     JPanel jp1 = new JPanel();
     JButton ok1 = new JButton("OK");
     public abc()
          this.getContentPane().setLayout(new BorderLayout());
          this.getContentPane().add(jp1,BorderLayout.CENTER);
          jp1.add(ok1);
          ok1.addActionListener(this);
          ok1.setActionCommand("ok1");
     public void actionPerformed(ActionEvent e)
          if (e.getActionCommand().equals("ok"))
               System.out.println("Inside action performed method");
          else if (e.getActionCommand().equals("ok1"))
          JFrame j1 = new JFrame();
          JPanel jp2 = new JPanel();
          JButton btn1 = new JButton("OK");
          j1.getContentPane().add(jp2);
          jp2.add(btn1);     
          btn1.addActionListener(this);
          btn1.setActionCommand("ok");
          j1.show();
          j1.pack();
          j1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
public static void main(String args[])
          abc ABC = new abc();
          ABC.show();
          ABC.pack();
Now here in this code the line
j1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
closes the application itself. What I want is only the JFrame closes while the main Dialog stills stays in context.
Can someone help with me how I can achieve the same.
Regards.

There is a dialog it has a OK button. When I click the OK button a frame opens with another OK1 button in it.
Now if I click the "x" sign of the frame it should be disposed without doing anything. frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE)But if I click the OK1 button then also the frame should be disposed but
after doing something other processing corresponding to the OK1 button.
OK1.addActionListener( new ActionListener() {
    public void actionPerformed(ActionEvent e) {
          // do processing
         frame.setVisible(false);
         // add this if you want to remove the frame from memory and recreate it when it needs to be opened
         frame.dispose();
})>
And within all this the parent(JDialog) and the child(JFrame) should be modal.A JFrame unfortunately cannot be modal, so you shd use a JDialog instead.
