у меня естьhibernate.cfg.xml файл вкорневая папка проекта.

Если я запускаю приложение, содержащее:

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

он падает вconfigure() метод со следующим сообщением:

Не удалось найти ресурс cfg.xml [hibernate.cfg.xml]

Выход:
