Мой следующий код работает на моей Windows, но не работает на моем Монетном дворе Linux. Добавлены все соответствующие библиотеки. я получаю это исключение для createEntityManagerFactory строки:javax.persistence.PersistenceException с помощью createEntityManagerFactory
javax.persistence.PersistenceException: Explicit persistence provider error(s) occurred for "JPA_probaPU" after trying the following discovered implementations: org.eclipse.persistence.jpa.PersistenceProvider from provider: org.eclipse.persistence.jpa.PersistenceProvider
Мой ява файл:
package jpa_proba;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import org.eclipse.persistence.exceptions.EntityManagerSetupException;
public class JPA_proba {
public static void main(String[] args) {
try{
EntityManagerFactory emf = Persistence.createEntityManagerFactory("JPA_probaPU");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
//Integer id, String isbn, String szerzo, String cim, String mufaj, int ar, int elerheto
Konyv k = new Konyv(null, "654654444444", "Kiss Béla", "Hogyan ne csináljunk semmit?", "dráma", 500, 1);
em.persist(k);
em.getTransaction().commit();
}
catch(Exception ex){
System.out.println(ex);
}
}
}
