Hello World com Spring MVC

Boa noite pessoal,

Estou tentando fazer um Hello World com SpringMVC e usando o WildFly 8.0 como servidor.

Meu problema é que o servidor sempre retorna “404 - not found”.

Não consigo colocar os links do pastebin aqui, o GUJ está me proibindo, então vou tentar colocar nos comentários do tópico.

Se alguém conseguir me ajudar, eu ficaria muito grato.

Caso alguem queira tentar entender o código:

/*  OlaMundoController.java */
package br.com.caelum.tarefas.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
public class OlaMundoController {
 
    @RequestMapping("/olaMundoSpring")
    public String execute() {
        System.out.println("Executando a lógica com Spring MVC");
        return "ok";
    }
   
}
 
<!--    ok.jsp  -->
