Spring mvc + ajax

Bom dia, galera!

Estou fazendo os exercicios da apostila FJ-21 da caelum e travei no 11.21(exercicios: ajax).

Bom, a minha dificuldade é adicionar no arquivo spring-context.xml essa linha:

Em todos os lugares que eu coloquei, deu um erro no console. E eu acho que a minha função não funcionou por causa disso.

lista.jsp

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

<html>

<head>
	<script type="text/javascript" src="/resources/js/jquery.js"></script>
	
	<script type="text/javascript">
	function finalizaAgora(id) {
		$.post("finalizaTarefa", {'id' : id}, function() {
		$("#tarefa_"+id).html("Finalizado");
		});
	}
	</script>
</head>	

<body>

<a href="novaTarefa">Criar nova tarefa</a>
<br /> 
<br />
<table>
<tr>
<th>Id</th>
<th>Descrição</th>
<th>Finalizado?</th>
<th>Data de finalização</th>
</tr>
<c:forEach items="${tarefas}" var="tarefa">
<tr>
<td>${tarefa.id}</td>
<td>${tarefa.descricao}</td>
<c:if test="${tarefa.finalizado eq false}">
	<td id="tarefa_${tarefa.id}"><a href="#" onClick="finalizaAgora(${tarefa.id})">Finaliza agora!</a></td>
</c:if>
<td><fmt:formatDate value="${tarefa.dataFinalizacao.time}" pattern="dd/MM/yyyy"/></td>
<td><a href="mostraTarefa?id=${tarefa.id}">Alterar</a></td>
<td><a href="removeTarefa?id=${tarefa.id}">Remover</a></td>
</tr>
</c:forEach>
</table>
</body>
</html>

tarefasControllers.java

@RequestMapping("finalizaTarefa")
	public void finaliza(Long id, HttpServletResponse response) {		
		TarefaDAO dao = new TarefaDAO();
		dao.finaliza(id);
		response.setStatus(200);
	}

TarefaDAO

public void finaliza(Long id){
		
		Tarefa tarefa = new TarefaDAO().buscaPorId(id);
		
		String sql = "update tarefas set finalizado=?, dataFinalizacao=? where id=?";
		
		try{
			PreparedStatement stmt = this.connection.prepareStatement(sql);
			
			stmt.setBoolean(1, true);
			
			stmt.setDate(2, new Date(Calendar.getInstance().getTimeInMillis()));
			
			stmt.setLong(3, tarefa.getId());
				
			stmt.execute();
			stmt.close();
			
			System.out.println("DADOS ALTERADOS COM SUCESSO!");
		}catch(SQLException e){
			throw new RuntimeException(e);
		}				
	}
