JSP : Model View Controller Architecture

In Model 1, a request is made to a JSP and then that JSP handles all responsibilities for the request, including processing the request, validating data, handling the business logic, and generating a response. The Model 1 architecture is commonly used in smaller, simple task applications due to its ease of development. Although conceptually simple, this architecture is not conducive to large-scale application development because, inevitably, a great deal of functionality is duplicated in each JSP. Also, the Model 1 architecture unnecessarily ties together the business logic and presentation logic of the application.
