public class OrderPage

extends HttpServlet

Shows all items currently in ShoppingCart. Clients have their own session that keeps track of which ShoppingCart is theirs. If this is their first visit to the order page, a new shopping cart is created. Usually, people come to this page by way of a page showing catalog entries, so this page adds an additional item to the shopping cart. But users can also bookmark this page, access it from their history list, or be sent back to it by clicking on the "Update Order" button after changing the number of items ordered.
