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:

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.
