java.lang.RuntimeException: не удалось разрешить блок персистентности

/ 09 ноября 2019

У меня возникла проблема при попытке изменить свойства модуля сохраняемости, который я использовал в своем проекте (я хотел, чтобы он отбрасывал и создавал таблицы, но он всегда сбрасывался на ноль), поэтому я удалил его, создал новый модуль постоянстваи заменил имена во всех аннотациях @PersistenceContext (unitName = "").

Но теперь я получаю следующие исключения для этих двух классов фасадов 

package src;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

@Stateless
public class SubjectFacade extends AbstractFacade<Subject>{
    @PersistenceContext(unitName = "A3PU")
    private EntityManager em;

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

    public SubjectFacade() {
        super(Subject.class);
    }
}

java.lang.RuntimeException: Could not resolve a persistence unit corresponding 
to the persistence-context-ref-name [src.SubjectFacade/em] in the scope of the module called [Assignment_3]. 
Please verify your application.

    @PersistenceContext(unitName = "A3PU")
    private EntityManager em;

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

    public StudentFacade() {
        super(Student.class);
    }
}

Это часть более крупного задания, но я никак не могу решить эту проблему. Мой код не имеет каких-либо сложных алгоритмов или транзакций. Буду признателен за любую помощь (трассировка стека ниже).
