No, because there is no such thing as MVC1 and MVC2. There's just MVC.

Now, if you meant to ask about the difference between Model 1 and Model 2 with respect to web applications, perhaps this article will help you out.

I was going to say "1". Your answer was more helpful.

MVC is a design pattern. It contains two models. MVC Model 1 MVC Model 2.Struts framework implements MVC Design Pattern. Struts can implement Model 1 and Model 2. Model 2 most properly describes the application of MVC in a Web-Application context.

Following are the important feature of MVC1 architecture:
(1) HTML or JSP files are used to code the presentation. JSP files use java beans to retrieve data if required.
(2)MVC1 architecture is page-centric design all the business and processing logic means any JSP page can either present in the JSP or may be called directly from the JSP page.
(3)Data access is usually done using Custom tag or through java bean call.

Therefore we can say that in MVC1 there is tight coupling between page and model.

Following are the important feature of MVC2 architecture(
(1)This architecture removes the page-centric property of MVC1 architecture by separating Presentation Control logic and Application state
(2)In MVC2 architecture there is one Controller which receive all request for the application and is responsible for taking appropriate action in response to each request. Second one is Model which is represented by JavaBeans business object and database. Third one is View or is JSP page it takes the information provided by Controller and Module and presents it to user.Raj

The main difference between MVC-I and MVC-II is
in MVC-I all the view control elements are implemented using Servlets.
in MVC-II the view is implemented using JSP and the controller is implemented using Servlets as JSP provides better user interface than Servlets.

Again, calling them MVC1 and MVC2 just makes you look uninformed. MVC is MVC. The two patterns are called Model 1 and Model 2.

Using correct terminology makes you look like you know what you are talking about. Using silly terms does not.
