                Please add the ability to list/show Orders
                
                You will need to code/configure:
                
                a Servlet
                a list Orders jsp
                a show Order jsp
                edit the index.jsp to add the link to list Orders jsp
                
                On the list Orders jsp, please show the Order Number 
                and the Order Date
                
                I want to see all the Order details, which includes all
                the OrderItems for the Order
                
                On the show Order jsp, I want to see a list of OrderItems
                for the Order, I want to see a link from the displayed
                OrderItem to the show Product jsp to see the details for
                the Product
                
                I also want to see a link from the show Order to the 
                show Customer jsp
                
                your OrderDAO will need a method to findAllOrders
                and a method to findOrderbyId
                
                your Order and OrderItem Entity classes must be written 
                and tested
                
                REMEMBER: If you edit an Entity or Action class you must run
                    Maven Install to rebuild the jar file needed 
                    by the web project
