org.springframework.web.servlet.PageNotFound noHandlerFound WARNING: No mapping found for HTTP reque

[Debashis Mandal]

I am new to the Spring MVC Framework. I am trying to setup a sample Code base using Spring 4 in Eclipse Juno and Tomcat(V 7.0.61). I tried different options stated in different forum but none of them working. Any help to resolve this issue will be very much appriciated!

Below is the code:

Web.xml

       <display-name>Spring MVC Application</display-name>
    
       <servlet>
          <servlet-name>HelloWeb</servlet-name>
          <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
          </servlet-class>
          <load-on-startup>1</load-on-startup>
       </servlet>
    
       <servlet-mapping>
          <servlet-name>HelloWeb</servlet-name>
          <url-pattern>/</url-pattern>
       </servlet-mapping>
     
    </web-app>

HelloController.java

    package com.example;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.ModelMap;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    @RequestMapping("/hello")
    public class HelloController{
     
       @RequestMapping(method = RequestMethod.GET )
       public String printHello(ModelMap model) {
    	   
    	   
          model.addAttribute("message", "Hello Spring MVC Framework!");
    
          return "hello";
       }
    }

Can you verify that HelloController is being packaged as part of the war that is deployed into tomcat?

It is already there!
