Java menu problem

Question

Hi,
I have a java menu that pops up to the side on mouse over, however when the browser window is fully expanded on screen the submenu positions its self over the top of the main menu, not on the side.
How can this be corrected?

                 JList  c =  (JList) e.getComponent();
                 int x = e.getX();
                 int y = e.getY();
                if(!list.isSelectionEmpty()&& list.locationToIndex(e.getPoint()) == list.getSelectedIndex())
                     int count = c.getModel().getSize();
                     int cal = count * 18;
                     if(y <= cal)
                         popUp.show(list, x, y);                        
       frame.add(new JScrollPane(list));
