Problemas ao adicionar um dado utilizando Vraptor + JPA

Estou praticando um pouco com Vraptor, criando um pequeno projeto com um crud simples.

Quando tento adicionar algo, ele me retorna isso:

`15:13:28,835  INFO [LinkToHandler       ] Registering linkTo component

Abaixo segue minhas classes:
`

@ApplicationScoped
public class EntityManagerProducer {

private EntityManagerFactory factory = Persistence.createEntityManagerFactory("reserva");

@Produces
@RequestScoped
private EntityManager getEntityManager() {
	System.out.println("Criando entity");
	return factory.createEntityManager();
}

private void close(@Disposes EntityManager manager) {
	manager.close();
}

}
`

public class MaterialDao {

private EntityManager em;

@Inject
public MaterialDao(EntityManager em) {
	this.em = em;
}

@Deprecated
public MaterialDao() {
}

@Post
public void salva(Material material) {
	em.getTransaction().begin();
	em.persist(material);
	em.getTransaction().commit();
}

}

`@Controller
public class MaterialController {

private MaterialDao materialDao;
private Result result;

@Inject
public MaterialController(MaterialDao materialDao, Result result) {
	this.materialDao = materialDao;
	this.result = result;
}

@Deprecated
public MaterialController() {
}

@Post("materiais/salva")
@IncludeParameters
public void salva(@Valid Material material) {
	materialDao.salva(material);
	result.redirectTo(IndexController.class).index();
}

public void lista() {
}

}
`

Alguém poderia me ajudar?
