Мобильная версияI have an Entity class calle Publication, a method called getAllPublication that return List
, but my query inside the method has a resultList of type List, how can I retrieve a list of publication entity fromthe List:
-here the method :
public List getAllPublication() {
List listePublication;
Query q;
em.getTransaction().begin();
q=em.createQuery("SELECT c.titrePublication,
c.datePublication, c.corps,p.login FROM Publication c JOIN c.employee p ");
listePublication = q.getResultList();
//ArrayList results = new ArrayList();
//for (Object[] resultat : listePublication)
//results.add((Publication) resultat[0]);*/
em.getTransaction().commit();
return results;
}
< /code>
package entities;
import java.io.Serializable;
import javax.persistence.*;
@Entity
@NamedQuery(name="Publication.findAll", query="SELECT p FROM Publication p")
public class Publication {
@Id
@Column(name="\"idPublication\"")
