Thanks David, but I think i've come up with something that answers my
question:

public void actionPerformed(final ActionEvent e) {
    if (FILE_OPEN.equals(e.getActionCommand())) {
        SwingUtilities.windowForComponent(MyJMenuBar.this)
                .firePropertyChange("fileOpen", 0, 1);
    }
}

As far as you can understand each menu item is initialized with an
instance of AbstractAction implementation with similar code. The last
step is that Controller class within main window handles fired
property change within its code.
