Spring + hibernate 3 "No Hibernate Session bound to thread" But i have a transaction manager configured

Question

i have this problem: "No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here". I'm using spring + hibernate 3. I already had checking this in other questions, but they don´t solve my problem. Here, my applicationContext of Spring.

`<bean id="ServGenerico" class="servico.AbsServicoGenerico" />
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"

My service

@Service
@Transactional
public class ServGrupoDeAcao extends AbsServicoGenerico<GrupoDeAcao>
{

    public ServGrupoDeAcao()
    {
        super();
        setDao(new GrupoDeAcaoDao());
    }

    public ServGrupoDeAcao(Class<?> clazz)
    {
        super(clazz);       
    }   

    /*@Autowired
    @Qualifier("grupoDeAcaoDao")
    public void setDao(GrupoDeAcaoDao dao)
    {
        super.setDao(dao);
    }*/
}

And my DAO

@Repository
@Transactional
public class GrupoDeAcaoDao extends AbsDao<GrupoDeAcao, Long>
{

    @Override
    public boolean equals(Object object)
    {
        // TODO Auto-generated method stub
        return false;
    }   

    @Override
    public int hashCode()
    {
        // TODO Auto-generated method stub
        return 0;
    }   

    @Override
    public Object executarConsultaPersonalizada(NomeMetodo nome,
            Parametros parametros)
    {
        // TODO Auto-generated method stub
        return null;
    }

    public boolean daoCompativel(Class<?> clazz)
    {
        return GrupoDeAcao.class.equals(clazz);
    }

The class AbsDao is a generic class that have in your methods, save, update e etc. And this class have the @Repository and @Transactional Anotations
