Answer 1

you must have to set the following property true for add listener on JDialog.

 jDialog.setFocusable(true);

then by adding key listener you can disable the or avoid the escape key by following code

    jDialog.addKeyListener(new KeyListener() {
     @Override
     public void keyPressed(KeyEvent e) {
                   write any code related to kdy
     }
    });

Answer 2

I have found the perfect solution for the above problem.

First of all we have to set the JDialog focusable:

 jDialog.setFocusable(true);

then apply following code to disable the escape key:

    jDialog.addKeyListener(new KeyListener() {
         @Override
         public void keyPressed(KeyEvent e) {
           // Catch ESC key stroke.
           if (e.getKeyCode() == KeyEvent.VK_ESCAPE) {
              e.consume();
           }
         }
        });
