Duvida ao criar primeiro Projeto Spring MVC

Programação
#1

Bom galera estou com problema ao criar meu primeiro projeto simples usando Spring MVC.

Web.xml

`<?xml version="1.0" encoding="UTF-8"?>

<display-name>contas</display-name>

 <welcome-file-list>
	<welcome-file>index.html</welcome-file>
	<welcome-file>index.htm</welcome-file>
	<welcome-file>index.jsp</welcome-file>
	<welcome-file>default.html</welcome-file>
	<welcome-file>default.htm</welcome-file>
	<welcome-file>default.jsp</welcome-file>
</welcome-file-list>

<!--Declaração do servlet do Spring MVC abaixo  -->
<servlet>
	<servlet-name>spring mvc</servlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	<init-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/spring-context.xml</param-value>
	</init-param>
</servlet>

<servlet-mapping>
	<servlet-name>spring mvc</servlet-name>
	<url-pattern>/</url-pattern>
</servlet-mapping>

`

spring-context
`<?xml version="1.0" encoding="UTF-8"?>

<!-- Pacote Base na minha aplicação -->
<context:component-scan base-package="br.com.caelum.contas.controller" />
<mvc:annotation-driven /> <!-- Vamos usar as anotações. -->

<bean
	class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/views/" />
	<property name="suffix" value=".jsp" />
</bean>

`

Classe java
`package br.com.caelum.contas.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class OlaMundoControler {

@RequestMapping("/OlaSpring")
public String executa() {
	System.out.println("Executando um comando com Spring");
	return "ok";
}

}
