Many application frameworks implement the Model-View-Controller (MVC) paradigm,
which is also popular in GUI application design. In a web app, the most common
division of function looks like this:
* Model = beans
* View = JSP pages
* Controller = servlet
Business logic can be implemented in a variety of ways, but is most often found in
action classes managed by the controller, in JavaBeans, or in EJBs.
For one example of a framework that is organized in this manner, check out the
Struts framework at <http://jakarta.apache.org/struts>.
