Hi,


I am using hibernate 3.0.5, with. The mapping document Customer.hbm.xml and Hibernate.hbm.xml are attached. Also attached are 3 classes a test class, utility class and class I want to map.

Mapping documents:

Code between sessionFactory.openSession() and session.close():

// Session created as follows
Configuration cfg = new Configuration();
cfg.configure();
SessionFactory factory = cfg.buildSessionFactory();

public static List getCustomers()
{
HibernateUtil util = new HibernateUtil();
Session session = util.getSession();
Query query = session.createQuery("from customer");
List customers = query.list();
return customers;
}

Name and version of the database you are using:
MySQL 4.1

The generated SQL (show_sql=true):
