Model 2
Encyclopedia : M : MO : MOD : Model 2
- This article is about the Java design model. For the arcade board, see Sega Model 2.
Model 1 is simpler and only recommended for small applications. Model 2 is recommended for medium- and large-sized applications. It uses the Model-View-Controller (MVC) design pattern to separate presentation from content.
In a Model 2 application, requests from the client browser are passed to the controller, which is a servlet. The controller decides which view (JSP) it will pass the request to. The view then invokes methods in a JavaBean (which may access a database) and returns the Response object to the Web container, which is then passed on to the client browser.
