Hi, I'm using

Hibernate 3.2.0 with Java 5 and Eclipse.
PostgreSQL 8.2
Win XP

I don't have any compile errors, but at runtime occurs the following error:


Initial SessionFactory creation failed.java.lang.NoClassDefFoundError:

I use the following main class:

public class SaveUser {
public static void main(String[] args) {
User user = new User("Horst", "Hans", "Horst@Hans.de");
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.persist(user);
tx.commit();
session.close();
}
}


I don't know why there can't be initialized a SessionFactory.
Can anybody help me out?

You'll need the ejb3-persistence.jar in your runtime classpath. You can get it from the lib directory of the hibernate entitymanager download.

Thanks for your reply, but I already had included this file. Is there anything else which could cause the problem?
