Hi All,

This is regarding the migration of my application from Hibernate2.0 to Hibernate3.0.

As per the documentation provided on the site, I had made the following changes in my application:

1. API Changes: I had changed all the entries of net.sf.hibernate.* to org.hibernate.*
2. DTD Changes: Made the DTD changes to 3.0...

When I am running my application, my data is not being commited to the database. At the same time I could not see any exception being thrown.

Is there anything I am missing... like any particular attribute to be set in the xml files...

Its bit urgent, please help me at the earliest.

Thanks in advance

Does any SQL show in your console ?

Enable DEBUG level on org.hibernate.SQL if isn't enabled yet.


Have you tried reverting to Hibernate 2, using the same programs ?

I have succesfully converted several Hibernate 2 apps Hibernate 3 and never had a non committing issue.

Hi Giulio

I got my application working with hibernate 3.0.
With hibernate2.0, transaction.commit() is sufficient to get the database changes to be effected.
With Hibernate3.0, I came to know that "session.flush()" is also necessary before issuing a transaction.commit();

If I am wrong, please correct me.

Well, I usually use this (here simplified) construct :

Transaction tx = session.beginTransaction();

try {

... do some work
session.saveOrUpdate(object);

tx.commit();
}
catch (Exception ex) {
tx.rollback();
throw ex;
}
finally {
session.close();
}


Maybe you didn't issue a saveOrUpdate() call ?
