Hi, I have a very very strange problem, which I cannot almost beleive myself but it looks like hibernate is clearing out my table!
I have a table which I insert a row to, and then verify the row by a ordinary select to the table. Ok everything ok.
Then I startup my .war application and suddenly the table is empty!

Here are some info:
Database: Mysql (latest version)
Tomcat 5.5.17
IDE: Eclipse WTP 3.1.2
Hibernate: 3.1.3

Session creation:
private static final SessionFactory sessionFactory;
sessionFactory = new Configuration().configure().buildSessionFactory();

Hibernate-mapping default.

CustomerFactory object:
Session session = HibernateSessionFactory.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query query = session.createQuery("select x from Customer as x WHERE x.id = :cid");
query = query.setParameter("cid", 1);
Customer customer =
(Customer)query.uniqueResult();
session.getTransaction().commit();
log.debug("Customer: " + customer);
(customer object always null)


Does anyone have a clue what I have messed up?

The default hibernate.properties file (I assume that's what you refer to, there is no default mapping for classes I guess) contain entries for schema export, like these:


I'd make sure that your shema is not regenerated by Hibernate upon startup. This is useful for testing, but it might be the cause of confusion in your case. The value 'validate' only checks that the mappings you defined match the database to some degree, so maybe you want that.
The generated log should also be able to help you verify this.

You were absolute right there, thank you and sorry for my blindness!
