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

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
