Hi. I'm new to Hibernate group. When I want to save my persistent domain object,I take an exception as :
HibernateException("unmapped property: " + propertyName);

My codes are shown below:

Session Bean method
public void createKesinOSSOgrenciKayit(AbstractOgrenciDTO ogrDTO, OgrenciNufusDTO ogrNufusDTO, OgrenciAskerlikDTO ogrAskerlikDTO,
OgrenciAdresDTO ogrAdresDTO, OgrenciHarcDTO ogrHarcDTO, OgrenciOSSDTO ogrOSSDTO) throws KesinKayitControllerAppException, KesinKayitControllerSysException, java.rmi.RemoteException{
try {
getOgrenciDAO();
getOgrenciNufusDAO();
AbstractOgrenciDO asilOgrenci = new AbstractOgrenciDO(ogrDTO);
ogrenciDAO.saveOgrenci(asilOgrenci);
//ogrenciDAO.refresh(asilOgrenci);

OgrenciNufusDO ogrenciNufus = new OgrenciNufusDO(ogrNufusDTO);
// EXCEPTION IS TAKEN BELOW
ogrenciNufusDAO.saveOgrenciNufus(ogrenciNufus);
} catch (DAOSysException dse) {
getSessionContext().setRollbackOnly();
throw new KesinKayitControllerSysException(dse.getMessage());
} catch (DAOAppException dae) {
getSessionContext().setRollbackOnly();
throw new KesinKayitControllerAppException(dae.getMessage());
}

}

}

DAOImpl save method

public void saveOgrenciNufus(OgrenciNufusDO ogrenciNufus)
throws DAOSysException, DAOAppException {
Session session = getSession();
try {
session.save(ogrenciNufus);
session.flush();
} catch (HibernateException he) {
throw new DAOAppException(
he.getMessage());
} finally {
closeSession();
}
}

Domain Object

public class OgrenciNufusDO{

private Long id;
private String anaAdi;
private String babaAdi;
private String medeniHali;
private String dogumYeri;
private String tcKimlikNo;
private String kutukIl;
private String kutukIlce;
private String kutukMahalleKoy;
private String ciltNo;

private String aileSiraNo;

//setters and getters
}

I think this problem is from the foreign key of id for OgrenciNufus. But I'm not sure and I couldn't solve the problem. Thanks for your interest.

When asking questions, give at least: the Hibernate version
# your mapping documents
# the Java code between sessionFactory.openSession() and session.close()
# the full stack trace of any exception that occurs
# the name and version of the database you are using
# a debug level Hibernate log excerpt is also appreciated
