Ошибка 500 при создании веб-приложения на Hibernate и Servlet

Добрый день. Создали базу данных, создали для нее Hibernate зависимости и сущности. Проверили работу без использования сервлета, все работает.

Вся информация по бд здесь

Код сервлета :

@WebServlet("/pasis")
public class MainServlet extends HttpServlet {
    // Входные данные
    static Map<String, String[]> map = new HashMap<String, String[]>();
    static {
        String[] q = {"июнь2016"};
        map.put("age", q);
        String[] f = {"Dog", "Cat"};
        map.put("type", f);
    }
    // Входные данные
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) 
    throws ServletException, IOException {
        resp.setContentType("text/html; charset=windows-1251");
        /*System.out.println("Pipekka");*/
        String result = HibernateUtil1.getAnimalsFromDb(map);
        System.out.println(result);
        resp.getWriter().append(result);
    }
}

Код HibernateUtil:

public class HibernateUtil {
    private static final SessionFactory sessionFactory = buildSessionFactory();
    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }
    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    public static void shutdown() {
        // Close caches and connection pools
        getSessionFactory().close();
    }
}

При запуске сервлета, выходит следующая ошибка.

Методы запуска работы Hibernate:

 public static String getAnimalsFromDb (Map<String, String[]> incomeRequest){
    Session session = HibernateUtil.getSessionFactory().openSession();
    Transaction transaction = session.beginTransaction();
    List<Animal> list = getAnimal(session,incomeRequest);
    String result = jsonPrint(list);
    transaction.commit();
    session.close();
    HibernateUtil.shutdown();
    return result ;
}

Повторюсь, что без сервлета, все запросы проходят и выполняются как нужно. При запуске сервера выходит эта ошибка.

P.S. Изначально выходила такая же ошибка, но с другими causes. Решили добавлением всех библиотек подгруженных Maven, в папку lib.
