To be more exact:

I tried to insert my method
boolean cancelClosing()
into the JBuilder generated code like

 public void jMenuFileExit_actionPerformed(ActionEvent e)
 {
    if( ! cancelClosing() )
      System.exit(0);
 }

The WINDOW.CLOSING event calls this also:

 protected void processWindowEvent(WindowEvent e)
 {
  super.processWindowEvent(e);
  if (e.getID() == WindowEvent.WINDOW_CLOSING)
  {
   jMenuFileExit_actionPerformed(null);
  }
 }


Now, if the user clicks jMenuFileExit, it works like I want: if
cancelClosing() returns false, the closing is canceled.
But if he clicks the frame's close button (WINDOW_CLOSING), cancelClosing()
is called, but can't cancel the closing.
