Here’s the scenario, I am working on a web-based application develped used JSP/Servlet technique, and we adopt MVC2 as an architectural design pattern, we put all the methods that make manipulation on database into one class, for example, addNewUser() , updateUserInfo (),
all methods that make connection to db and manipulate data are in one class.
what is the role of this class, controller or model?
That’s the (business) model.
The controller should be the servlet and the view should be the JSP.
