Getting access to menu from portlet in liferay

The below code describes the way of accessing menu items from the portlet. Here i have called it from jsp. The best thing about this is you can use the beautiful permission management of menu items of liferay as well without bothering about that. Writing services for fetching menu names from the layout tables will need more codes for permission managements......

Hope this helps.........
