36. The Coffee Break Application
This chapter describes the Coffee Break application, a set of web applications that demonstrate how to use several of the Java Web services APIs together. The Coffee Break sells coffee on the Internet. Customers communicate with the Coffee Break server to order coffee online. The server uses JavaServer Faces technology as well as Java servlets, JSP pages, and JavaBeans components. When using the server a customer enters the quantity of each coffee to order and clicks the Submit button to send the order.
The Coffee Break does not maintain any inventory. It handles customer and order management and billing. Each order is filled by forwarding suborders to one or more coffee suppliers.
The Coffee Break server obtains the coffee varieties and their prices by querying suppliers at startup and on demand.
