The Menu JSP Page
The main menu is a JSP page, which selectively displays menu options based on the user's current state. If the user has logged in, then the option to log into the movies store is not displayed, and the option to log out of the movies store is displayed. If the user has a shopping cart, then the option to list the shopping cart is shown. If the user has logged in, then the user name is retrieved from the session attribute and displayed to the page. Alternatively, if the user has not logged in, then the option to log into the movies store is displayed and the option to log out is not displayed.
These session values are retrieved using the session object and making a call to the getAttribute method.
