No mapping found for HTTP requ

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 here on this 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 are my relevant files:

web.xml

<?xml version='1.0' encoding='UTF-8' ?>

hello.jsp

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