package test;
import mywebapp.bean.data.Article;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class TestHibernate1 {
public static void main(String args[]) throws Exception {
Configuration config = new Configuration();
config.addClass(Article.class);
SessionFactory sessionFactory = config.buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
Article article = new Article("6","Montre");
session.save(article);
session.flush() ;
tx.commit();
} catch (Exception e) {
if (tx != null) {
tx.rollback();
}
throw e;
} finally {
session.close();
}
sessionFactory.close();
}

Je suppose que c'est peut etre le fichier de config qui porte un problème:
