ok!
So I need a listener class like HibernateListener and a Transactionfactory in
the config xml ?

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...

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 !
