NET Web form model—the separation between the application UI and business logic allowing for independent design, implementation and testing of each component. The Model represents the state of application and contains the business logic; the Controller is responsible for updating the Model and passing information to the View; the View is responsible for rendering the user interface representing the Model.

In the ASP. NET Web form application. Instead of mapping application requests to a file on disk representing the page, requests are mapped to Controller Actions. The Controller is a class that exposes these Actions. Controller Actions are public methods of the Controller class. Any public method you add to a Controller is automatically added as a Controller action so be careful since a Controller method can be executed by just typing in the right URL.

A Controller returns an instance of a class that derives from ActionResult. The framework provides many built-in types that derive from the ActionResult class. One of the more common ActionResult classes is the ViewResult which is used to display a specific View as a result of the requested action. Some other action results redirect to another controller, return a JSON object or return a file stream. Typically you do not return an ActionResult directly; instead you use a helper method to construct the ActionResult.

One example is calling the View method to create a ViewResult object. In MVC2, there is separate components for receiving and sending response. MVC1 associates the presentation logic with the business logic. MVC 2 isolates or disassociates the presentation logic from business logic.

In MVC 1, business logic and presentation Logic is combined so web designer and web developer cant work simulateously. Since both logics are separate that's why designer and developer can work together.

Doesn't support reusability of application components. Reusability of components. While controller is servlet and model is java class. In MVC1 there is tight coupling between page and model as data access is usually done using Custom tag or through java bean call. In MVC2 architecture there is only one controller which receives all the request for the application and is responsible for taking appropriate action in response to each request.

Is it helpful? Yes No. In MVC1, only one component is responsible for receiving request and sending response. JSP vs Servlets. JSF 1. JSF 2. Java 5 vs Java 6.
