How to know the point where one menu popUp is showed ?

Question

hi,
I need know the point where one popUp menu is showed, but I have problems to do it....
I can install actionListener for method actionPerformed of class AbstractAction but the event I get does not able to say the point...
In the documentation, I read it is possible install a listener for the mouse and select the popUpMenu with the condition
"if (e.isPopupTrigger())"
but it is not confortable to do it and in that case it is not easy too to manage the choice for the item selected...
Some advice please ?
I write down the code I use...
thank you to have one answer..

        Action sposta = new PopupMunuAction("sposta");
        Action cancella = new PopupMunuAction("cancella");

        jp.setComponentPopupMenu(popupMenu);
        enableEvents(AWTEvent.MOUSE_EVENT_MASK);
    // aggiungere il popupMenu FINE   -----------------
    } // costruttore
* Serve per gestire il menu popUp
class PopupMunuAction extends AbstractAction {

    public PopupMunuAction(String nome) {
        super(nome);
    public void actionPerformed(ActionEvent e) {
        String command = e.getActionCommand();
        if (command.compareTo(OpzPopMenu.NuovoAppuntamento.toString()) == 0) {
            JOptionPane.showMessageDialog(null, "NUOVO  one");
        if (command.compareTo(OpzPopMenu.SpostaAppuntamento.toString()) == 0) {
            JOptionPane.showMessageDialog(null, "SPOSTA  one");
        if (command.compareTo(OpzPopMenu.CancellaAppuntamento.toString()) == 0) {
            JOptionPane.showMessageDialog(null, "CANCELLA  one");
} // inner class PopupAction

If you mean where the panel was clicked, then it's as simple as adding this to your program:
        jp.addMouseListener(new MouseAdapter()
            @Override
            public void mousePressed(MouseEvent e)
                if (e.getButton() == MouseEvent.BUTTON3) // if right clicked
                    // do whatever in here with the e.getX() and e.getY() results
                    System.out.println("[" + e.getX() + ", " + e.getY() + "]");                   
        });
