Answer 1

«tn.ooredoo. kpi.util.HibernateUtil "- Этот класс не был найден.

Это результат ссылки из неизвестного класса (вы не указали полную ошибку, поэтому невозможно сказать ТОЧНО, что происходит на)

Все, что я могу сказать наверняка что ваш класс косвенно ссылается на tn.ooredoo.kpi.util.HibernateUtil, и класс не может быть найден - также кажется, что класс, который не может быть расположен, является частью библиотеки, которая может быть исключена во время сборки или запустить (скорее всего, запустить.)
