PersistenceException: невозможно построить фабрику диспетчера сущностей, вызванную ClassNotFound

я использую play jpa и столкнулся с этим. Полный поиск Stackoverflow не смог найти решение.

Что я пытаюсь сделать, так это то, что при попадании на localhost:9000 HomeController должен добавить таблицу «Product» в базу данных «crud», которая уже создана в mysql. Так что это завершит мою первую программу jpa

Вот мой Persistence.xml

import javax.persistence.Persistence;

public class HomeController extends Controller {

    private final FormFactory formFactory;
    private final HttpExecutionContext ec;

    @Inject
    public HomeController(FormFactory formFactory, HttpExecutionContext ec) {
        this.formFactory = formFactory;
        this.ec = ec;
    }

    public Result index() {
        //Create a database and add some entries
        Product newproduct=new Product();

        EntityManagerFactory entityManagerFactory= Persistence.createEntityManagerFactory("test");
//Stuck at the above statment
        EntityManager entityManager=entityManagerFactory.createEntityManager();
        entityManager.getTransaction().begin();


        newproduct.setEan("111");
        newproduct.setName("Lapy");
        newproduct.setDescription("Uska description");

        entityManager.persist(newproduct);
        entityManager.getTransaction().commit();

        entityManager.close();
        entityManagerFactory.close();
        return ok(views.html.index.render("Database created check mysql"));
    }
}

EntitymanagerFactory не может загрузить класс модели Product. Я пробовал различные решения на этом сайте, иначе я бы не опубликовал.
