Доброго времени суток... Столкнулся с такой проблемой: пытаюсь добавить в минимальный проект веб-приложения в NetBeans поддержку Hibernate, создал одну сущность, а так же класс для доступа к EntityManager:
| Код |
import interfaces.factoryes.IPersistenceFactory;
import javax.ejb.Singleton;
import javax.persistence.EntityManager;
import javax.persistence.Persistence;
import javax.persistence.PersistenceContext;
@Singleton
public class PersistenceFactory implements IPersistenceFactory {
@PersistenceContext(unitName = "jfrmPU")
private EntityManager entityManager;
public PersistenceFactory() {
this.entityManager = Persistence.createEntityManagerFactory("jfrmPU").createEntityManager();
}
public EntityManager getEntityManager() {
return this.entityManager;
}
}
|
Дабы протестировать его работу, сделал тестовый сервлет, где просто создал объект этого класса, в результате чего в логах появилось:
До перехода на /jfrm/Test:

Хотя сразу после деплоя в базе создается таблица для созданной сущности...
Подскажите, плс, чего я делаю неправильно... |
