MVC

A very basic MVC framework developed using Java servlets

Design

The DispatchServlet(front-controller) is responsible for routing the url to the corresponding application controller. Application router uses Model to render View

Usage: Add the url mappings in the init method of DispatchServlet

Here, we define 2 routes in this case, we maped  “/hello” to Index2 and “/” to Index

public void init() {
   ..
   ..
   pathToViewname.put("/hello", "Index2");
   pathToViewname.put("/", "Index");		
}

Index2 and Index are to be added in org.Framework.Handler and implement AppController interface. The interface is responsible to render corresponding view using Model.

Here, The views for Index and Idex2 controllers are Index.jsp and Index2.jsp respectively

Please have a look into code for clarity
