Prezados Colegas,
Estou com problemas para listar objetos no banco POSTGRES, os logs apontam para “createCriteria is not valid without active transaction”
minha hibernateDAO é :
/**
*
* @author cristofe Rocha
*/
import java.util.List;
import br.ifrr.entity.*;
import org.hibernate.*;
import org.hibernate.Session;
public class UsuarioDAOHibernate implements UsuarioDAO {
@SuppressWarnings({"unchecked", "rawtypes"})
private Session sessao;
....
public List<Usuario> listar() {
[b] return this.sessao.createCriteria(Usuario.class).list();[/b]
}
}Segue os logs abaixo:
Gostaria de saber como tornar válido uma createCriteria para realizar a consulta no banco de dados para alimentar minha dataTable.
Segue os logs abaixo
