MVC stands for model view controller.If you take a Struts
web application then view consists of JSP . Its only to
show the client the view part not any other part. The
Controller will the action Servlet. Action Servlet
basically controlls the request from the view part and
calls respective Action class for business logic processing
and fetching data from the database.The model part consists
of Action class and helper class. It purely consists of the
business logic as well as the interface to access the
layer. The advantage of this pattern is Loose coupling.
Lets say you want to add the text field in JSP. That will
not required to change your Action class or Action Servlet.
