This has nothing in particular to do with Wicket, and would be hard to
answer without knowing the details of what you are doing for transaction
management.

rendering a page for an email: org.hibernate.HibernateException: createCriteria is not valid without active transaction
Hi all,
I have coded the following to render a mail,
Application app;
try{
app=MyApplication.get();
}catch(Exception e){
app=new WicketTester().getApplication();
}
final Application app2=app;
final ExecutorService service = new ScheduledThreadPoolExecutor(1) {
@Override
protected void beforeExecute(final Thread t, final Runnable r) {
Application.set(app2);
};
@Override
protected void afterExecute(final Runnable r, final Throwable t) {
Application.unset();
}
};
service.submit(new ThreadMail(destinatarios, clazz, p));
But, I got a org.hibernate.HibernateException: createCriteria is not valid
without active transaction
when I tried to load an entity in a model to be used in the PageMail.
How can I attach the Transaction to the thread to get this working?
thanks in advance

Re: org.hibernate.HibernateException: createCriteria is not valid without active transaction
Yes i did it...
this is DAO and impl
public interface Dao {
@Transactional
void delete(T o);
T load(long id);
@Transactional
void save(T o);
@Transactional
List findAll();
int countAll();
}
and the implemetation is
public abstract class AbstractHibernateDaoImpl
implements Dao {
private Class domainClass;
private SessionFactory sf;
public AbstractHibernateDaoImpl(Class domainClass) {
this.domainClass = domainClass;
}
public SessionFactory getSessionFactory() {
return sf;
}
public void setSessionFactory(SessionFactory sf) {
this.sf = sf;
}
public void delete(T object) {
getSession().delete(object);
}
@SuppressWarnings("unchecked")
public T load(long id) {
return (T) getSession().get(domainClass, id);
}
public void save(T object) {
getSession().saveOrUpdate(object);
}
@SuppressWarnings("unchecked")
public List findAll() {
Criteria criteria = getSession().createCriteria(domainClass);
return (List) criteria.list();
}
public int countAll() {
Criteria criteria = getSession().createCriteria(domainClass);
criteria.setProjection(Projections.rowCount());
return (Integer) criteria.uniqueResult();
}
public Session getSession() {
// presumes a current session, which we have through the
// OpenSessionInViewFilter; doesn't work without that
return sf.getCurrentSession();
}
}

Hello Richard,
Maybe you need to use @Transactional above your dao method?
Hope this helps.

Hello all,
i try to do a simple web application with the classic layout
Wicket->Spring->Hibernate
When i try to make a simple request i receive the following error.

Root cause:

transaction
In IMHO all file conf seams to be correct correct... bat i don't undestand
hibenate dosen't find the correct session.
At UI level i load the data with LoadableDetachableModel
IModel contactsModel = new LoadableDetachableModel() {
protected Object load() {
return
WicketApplication.get().getContactService().findAllContacts();
}
};

Re: org.hibernate.HibernateException: createCriteria is not valid without active transaction
a HibernateListener is something completely different.It is not required to
config a TransactionFactory in your config xml. There is implicitly always
one.. (if I remember well, since I always use Spring to configure my
Hibernate...)
I suggest that you look first to some hibernate examples, since these issues
are not related to wicket.

AW: org.hibernate.HibernateException: createCriteria is not valid without active transaction
ok!
So I need a listener class like HibernateListener and a Transactionfactory in
the config xml ?

Betreff: Re: org.hibernate.HibernateException: createCriteria is not valid

Indeed, when you start a transaction and get an object from the database,
hibernate wil persist changes to that object when you transaction (and thus
sesseion) is still open.
This is normal behaviour.
Note that it is in most cases a bad habit to use manual transaction
management...

Re: org.hibernate.HibernateException: createCriteria is not valid without active transaction
Indeed, when you start a transaction and get an object from the database,
hibernate wil persist changes to that object when you transaction (and thus
sesseion) is still open.
This is normal behaviour.
Note that it is in most cases a bad habit to use manual transaction
management...

AW: org.hibernate.HibernateException: createCriteria is not valid without active transaction
How can I do it manually?
For example: I have a "DataProvider" class with a method:
public static Administrator getAdministrator(Integer id) {
Administrator administrator= (Administrator)
HibernateUtil.getSessionFactory().getCurrentSession().createCriteria(Administrator.class).add(Property.forName("id").eq(id)).uniqueResult();
return administrator;
}
I get the error message. How shall I modify the code?
I tried it with Transaction tx = ... and then tx.begin() tx.commit() -- but
then suddenly hibernate tries permanently to update an object... wired !

You did not setup your transactions properly.
Or you start your transaction manually, or if you like spring, you can let
spring manage it. (just add your transction annotations to your services,
and, done !

You did not setup your transactions properly. Or you start your transaction manually, or if you like spring, you can let spring manage it.
