Problème de cast avec @NamedQuery
Salut :)
j'ai créé deux classes: victimeDAOImpl et victimeDAOInterf
je fais le test avec JUnit de la methode : getVictimeById et ça retourne une erreur
ci dessous les données suivantes:
_les deux classes : VictimeDaoImpl.java et VictimeDaoInterf.java
_la classe : Victime.java
_la classe de test VictimeDaoTest.java

@Entity
@NamedQuery(name = "Victime.ById", query = "from Victime where victimeId = :victimeId")
@Table(name="victime" ,schema="testdb")
public class Victime implements Serializable {
@Id
@GeneratedValue
@Column(name="victime_id")
private int victimeId;
// code omitted |
