import java.awt.event.*;
import javax.swing.*;
class Testing extends JDialog
{
  public Testing()
  {
    setModal(true);
    setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
    JButton btn = new JButton("EXIT");
    getContentPane().add(btn);
    pack();
    setLocationRelativeTo(null);
    btn.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent e){
        JOptionPane.showMessageDialog(Testing.this,"Press Space Bar");
        System.exit(0);}});
    setVisible(true);
  }
  public static void main(String[] args){new Testing();}
}

post a sample program (similar to above) that demonstrates the problem,
showing how you are putting it together.
