MVC1 (Page-centric Architecture): There is no clear
distinction between view and a controller. In Java terms,
there is JSP page (view and partial controller) which itself
controls Business logic (Model) that is why it is also
called as page-centric architecture. Fig 2 below shows MVC1
implementation.

MVC2 (Servlet-centric architecture): MVC2 incorporates a
clear separation of view and controller. A controller
receives all the requests, retrieves data from a Model and
forwards it to next view for presentation.

In Java terms, there is a central Servlet (Controller) which
calls business logic (Model) and the forwards it particular
JSP page (View) that is why it is also called
servlet-centric architecture. Diagram below depicts MVC2
implementation

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..

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
