FIGURE 27-2. Interactions between Duke's Forest Components
As illustrated in
Figure 27-2
,
the customer interacts with the main interface of Duke's
Store, while the administrator interacts with the administration interface. Both interfaces
access a façade consisting of managed beans and stateless session beans, which in turn
interact with the entities that represent database tables. The façade also interacts with web
services APIs that access the Duke's Payment web service. The administrator also inter-
acts with the interface of Duke's Shipment, which can be accessed either directly through
Duke's Shipment or from the administration interface of Duke's Store by means of a web
service.
The most fundamental building blocks of the application are the Events and Entities pro-
jects, which are bundled into Duke's Store and Duke's Shipment along with the Duke's
Resources project.
