Não está criando a session bean da classe Banco

O projeto está funcionando normalmente, porém, não está mostrando na lista de session bean a classe br.com.caelum.livraria.dao.Banco, também não está executando o @PostConstruct. Não funciona com a anotação @Stateless, nem com @Singleton. Já verifiquei que todos os lugares onde a classe é chamada está sendo inicializada com @Inject, já dei clean no jboss, build clean, mas nada resolveu o problema.

//...
import javax.annotation.PostConstruct;
import javax.ejb.Singleton;
import javax.ejb.Startup;
//...
@Singleton
@Startup
public class Banco {
    //...
    @PostConstruct
    void aposCriacao() {
        System.out.println("[INFO] O Banco acabou de ser criado.");
    }
    //...
}
