Before Starting, I believe you must have basic idea about JAVA, SPRING and Spring MVC. For Spring MVC : http://waheedtechblog.blogspot.in/2012/08/spring-mvc.html In this tutorial , I will just tell you what are the basic thing that you need to start MVC. Step 1 : Create a class  @Controller public class HelloWorld {        @RequestMapping ( "/hello" )      public String helloWorld() {           return = "Hello World, Spring 3.0!" ;      } } 1 .

When Spring scans this class, it will recognize this bean as being a Controller bean for processing requests. 2 .The @RequestMapping annotation tells Spring that this Controller should process all requests beginning with /hello in the URL path. Step 2. Mapping Spring MVC in WEB.xml The entry point of Spring 3...

Controllers are responsible for receiving the request from the user and calling the back-end services. When a request is sent to the Spring MVC Framework the following sequence of events happen. The DispatcherServlet first receives the request. The DispatcherServlet consults the HandlerMapping and invokes the Controller associated with the request. The Controller process the request by calling the appropriate service methods and returns a ModeAndView object to the DispatcherServlet . The ModeAndView object contains the model data and the view name. ...
