Hi...
You would come across MVC framework in many books.
This framework specifies :
Bean - Model
JSP/Swing - View
Servlet - Controller
Bean contains all the business logic.
JSP/Swing is the view that the users see. The user is least concerned with what is going on in the background. Even at the design time, the designers should not be bother about the business logic that has to be implemented. So this
pattern was developed, where
Bean is the model. So you can use JSP or any other view & call the methods from the bean & show the results. So its not exactly JSP/Beans, it can be Swing/Beans too & the Bean that is implemented with JSP could be the same with Swing too.
Hope you get the point.
