The ExpressWeb used to implement web based e-business applications is based on popular MVC (Model-View-Controller) paradigm. The framework enforces the separation of presentation logic and business logic in an application. The framework also offers the benefits of applying specific security models to the presentation logic and business logic and role separation in a development team, where the work of a page designer can smoothly integrate with the separate work of a business logic developer. Three parts define the separation of presentation logic and business logic.

Model: Encapsulates the business logic and rules and does the business processing, usually implemented by Java Servlets and EJB's.

View:   Uses the result of the business process and constructs the response presented to the user, usually through HTML with JSP templates. The look of the site, how the pages are laid out, how the pages are related to one another, and what exactly appears on each page is defined in templates using template-scripting language and JSP Dynamic pages.

Controller:   Manages and controls the interaction between the user and the application. Usually the controller is a servlet that receives the user request and passes all the input parameters to the model servlet that does the actual work. Finally, the controller calls the view to generate the results. In addition controller manages sessions, template caching and the connection pool.
