enter image description herecurrently Hibernate. I create simply project. I did everything as is in course but i get "No Persistence provider for EntityManager named xxxx". I dont know what is wrong. I find many solutions but none work with me.
package pl.javastart.dao;
import pl.javastart.model.Book;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;
public class BookDaoImpl implements BookDao {
private EntityManagerFactory emFactory;
private EntityManager entityManager;
public BookDaoImpl() {
emFactory = Persistence.createEntityManagerFactory("myPersistenceUnit");
entityManager = emFactory.createEntityManager();
}
public void save(Book book) {
EntityTransaction tx = entityManager.getTransaction();
tx.begin();
entityManager.persist(book);
tx.commit();
}
public Book get(Long id) {
Book book = entityManager.find(Book.class, id);
return book;
}
public void cleanUp() {
entityManager.close();
emFactory.close();
}
}
