EntityManages NullPointerException, eclipselink + tomee + Jersey + Derby

Question

Я новичок в вопросах JPA, EJB и REST и хотел сделать несколько простых приложений crud. Когда я использую EntityManagerFactory, я получаю сущности из Derby, но проблема начинается, когда я хочу использовать транзакции для сохраняющихся объектов. Когда я пытаюсь ввести EntityManager, я получаю исключение NullPointerException. Я видел несколько тем в stackOverflow с аналогичными проблемами, но, видимо, я не могу решить свою проблему.

Я просто хочу запустить это приложение и сосредоточиться на концепции сохранения и не потратил еще несколько дней, пытаясь его настроить. Кроме того, я не знаю, почему я не могу предоставить DataSource в WEB-INF/resources.xml (WARNING - Failed to register in JMX: javax.naming.NameNotFoundException: Name "Resource/Crud/localDB" not found.)
