Доброго времени суток. Помогите решить проблему.
В стандартном коде HibernateUtil не работает строка "sessionFactory = new Configuration().configure().buildSessionFactory();"
| Код |
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
//creates the session factory from hibernate.cfg.xml
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (ExceptionInInitializerError ex) {
System.err.println("Initial SessionFactory creation failed: " + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
|
Конструктор контроллера (специально вынес сюда, чтобы легче было отлаживать):
| Код |
public class IndexController extends SimpleFormController{
private Session session;
public IndexController() {
session = HibernateUtil.getSessionFactory().getCurrentSession();
}
}

Выдает ошибку:

Смысл ошибки я понимаю, но где что нужно вписать - понятия не имею, только осваиваю это направление.
Подскажите, как это лечится.
