what is the difference between MVC1 and MVC2

Question

I am using MVC design pattern in jsp-servlet web application, and want to what is the exact difference between MVC1 and MVC2 , can someone help?

EDIT newly I hear that there is 2 versions of using MVC in servlet programming, I hear that in MVC1 there is kind of coupling between controller and view , but in MVC2 they overtake it, if someone know whether this is right or wrong I'll be very thankful.

Answer 1

It might be possible that you read this version in connection with asp.net MVC, as there different versions of that framework. There is no version 2.0 of the mvc pattern, just a version 2.0 of the asp.net MVC framework.

In context of jsp servlets see: Model 1 and Model 2. In a nutshell: Model 1 doesn't have a controller to dispatch requests, Model 2 does.

Answer 2

In MVC 1, controller and model,both are JSP. While in MVC2 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.
