The previous chapter explained the advantages of using a controller-centric, MVC architectural approach to developing Web applications.
In this chapter we examine a demonstration application developed with a framework. This J2EE application provides an example of an ecommerce site for a Movie Store application which tracks the user interaction at the Web site. The user must logon to the site to perform certain actions. As we will see in this chapter, the user interaction with the site is tracked using various objects which are retained by the application as an attribute of the user's session object.
