Hello to everybody!!I'm not getting to delete:

Code:

public void apaga (Estoque estoque){
  try{
     Session sessao = HibernateUtil.getSession();
     sessao.beginTransaction();
     sessao.delete(estoque);
     sessao.flush();
     HibernateUtil.commitTransaction();
  }catch (HibernateException ex){ex.printStackTrace();}

The only thing that happens is that the values become null, only the id keep the value!!!

The other part where I try to delete the object!!

Code:

Estoque estoq = new Estoque();
EstoqueDAO estoqDao = new EstoqueDAO();
estoq.setId(new Long (2));
estoqDao.apaga(estoq);

Hi!

I assume, that the reason, that your delete() does not work is, that Session.delete() expects a persistent object. The object estoq in your example is not linked with Hibernate. The following (in pseudo code) should work:

Code:

EstoqueDAO estoqDao = new EstoqueDAO();
Estoque estoqDao estoq = estoqDao.get(new Long(2));
estoqDao.delete(estoq);

Of course, get() and delete() should be in the same transaction!
Did that help?

All the best,

René
