The Difference between MVC Model1 and Model 2 is

That in model 1 we code the business logic within the JSP and directly access the DB within the JSP

Where as in model 2 we divide into 3portion Model View and Controller

Whole business logic is coded into Controller and as per the request the response is directed to a View

So in future is we have to make any change all the components are independent

We Do not use Model1 any more

In model1 there is no separation between the businesslogic and presentation logic and so we can't reuse the view component.

but in model 2 there is a separation between businesslogic and presentation logic and so we can easily reuse the view component.
