In MVC-1 the JSP acts as the model and the controller. In MVC-2, a seperate servlet acts as the controller while the JSP acts as the view.

In MVC-1 controller and model are not seperated -- they are "delegated". MVC-1 is used extensively in Swing, Like JTree, JTable etc. MVC-2 is a strict M-V-C model, controller and model are seperated, most web applications using this design pattern, and most MVC design patterns are based on MVC2, like Struts.

In MVC-2 the model implementing business logic and view  implementing presentation logic and controller implementing request-processing logic, data validation logic, session management. so the clean seperation of logics are available in MVC-2, suppose if any logic got disturbed there is no problem towards other logics. where as MVC-1 only either servlet or JSP should act as a controller there is no clean seperation of logics if any one got disturbed the entire project would be disturbed.

I am denoting both the mvc1 and mvc2 !

Features of MVC1:

  1. Html or jsp files are used to code the presentation. To retrieve the data JavaBean can be used.
  2. In mvc1 architecture all the view, control elements are implemented using Servlets or Jsp.
  3. In MVC1 there is tight coupling between page and model as data access is usually done using Custom tag or through java bean call.

Features of MVC2:

  1. The MVC2 architecture removes the page centric property of MVC1 architecture by separating Presentation, control logic and the application state.
  2. In MVC2 architecture there is only one controller which receives the entire request for the application and is responsible for taking appropriate action in response to each request.

In MVC 1, the view is not separate from the controller... ie the presentation logic as well as the business logic is written in the same place. However, in MVC 2, the view is separate from the controller. Thus the adv is that, MVC 2 is a properly latered architechture.... any changes can be incoorprated very easily without disturbing the existing code much. Also it makes ur application more flexible.... as since ur view is completely separate from the business logic, changing ur view representation from say jsp to jsf will be much easier...

The question itself is wrong. It should have been difference between Model1 and Model2. There is nothing called MVC1 in actual. The term MVC itself stands for Model-View-Controller, which clearly seperates the three layers, so how can there be a clubbing of the view and model in so called MVC1.What the people have been explaining here as MVC1 is actually Model1. Read this on wikipedia and refer to the 'Misconceptions' section,in particular the last line in the section:
http://en.wikipedia.org/wiki/Model_2
