Java Swing Scrollable JPopupMenu Rewuired

need a scrollable JPopupMenu as the menuitems are sometimes so many that they exceed the screen space and would not be visible.

[login to view URL] Please note that this is an urgent requirement and I need it by Sunday ## Deliverables I have developed an application which requires a Scrollable JPopupMenu.

I need a way to scroll through the menu items to avoid this visibility problem. What I have implemented I have implemented a Scrollable JPopupMenu which contains JButtons as menuitems. This solves my scrolling issue but I have many other problems. My Project requires the addition of JCheckBoxMenuItems to check and uncheck the menuitems each time the user clicks on the item.
