JSF CRUD and hibernate

Posted: Oct 27, 2006 2:30 PM

dear community,

I have generated JSF pages from existing entities, using NetBeans 5.5
and hibernate.In JSF table I can see my result sets from my table debts
in PostgreSQL database ,but when I try to edit them
or try to delete them I receive message in my browser
that " debts are successfully deleted" or "debts are successfully
updated". No errors, no exceptions,no errorneous logs in my Sun Application Server 9.

Problem is that my database remains untouched!!

I can't figure out is it a NetBeans problem or is it something with
hibernate.One user asked me:"do I use transactions?".

Generated code is starting a transaction and committing it.
Please let me know is this have a something with my "bug".
here is the code using transactions.

...
@Resource
private UserTransaction utx;

@PersistenceUnit(unitName = "HibenateAppPU")
private EntityManagerFactory emf;

private EntityManager getEntityManager() {
return emf.createEntityManager();
}

public String destroy() {

EntityManager em = getEntityManager();

try {
utx.begin();
Debts debts = getDugoviFromRequestParam();
debts = em.merge(dugovi);
em.remove(dugovi);
utx.commit();
addSuccessMessage("Dets was successfully deleted.");

}
catch (Exception ex) {

try {
addErrorMessage(ex.getLocalizedMessage());
utx.rollback();
} catch (Exception e) {
addErrorMessage(e.getLocalizedMessage());
}

}

em.close();
return "debts_list";
}

...

Any help is appreciated

best regards
Nikola
