Application Architecture

Shopping Cart follows a strict Model, Controller, View (MVC) architecture to organize its classes and files. Controller employs two packages to control the model and the view sections. One package contains classes performing different actions and other one contains classes acting as various action forms. The Model is organized into different packages where classes are devoted to interact with the database and to process business logic.



CONTROLLER LAYER

The Web Controller layer provides the mechanisms
that control the routing of each web request through the
system (the “C” in MVC). Its role is to entertain each
browser request, check its validity, invoke the classes
from the Business layer needed to process a request, to
handle certain processings (such as recording information
in the browser session), and finally to route the processed request to the appropriate JSP in the Presentation layer.
