No mapping found for HTTP request with URI [/helloweb/] in Dispatcherservlet with Name ' Helloweb ' Spring MVC

I ' m learning the Spring Framework, and I ' m doing the Helloweb tutorial on Tutorialspoint, and I can ' t get it working. I ' m using Spring MVC 4.0, and I ' m deploying my app from Netbeans 8.0 to a Glassfish Server. Http://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm

I looked for similar problems-on-site and on other sites as well, but the suggested solutions didn ' t work for me . I would really appreciate some help, because I ' m pretty sure I ' m missing something basic here.

Here is my relevant files:

Hellocontroller.java

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

You had a single controller in your app, mapped to (that's what /hello @RequestMapping("/hello") means). The URL for this controller is thus http://localhost:8080/HelloWeb/hello .
