Exception in thread "main" javax.persistence.EntityExistsException:
J'ai un petit souci avec une insertion.
Voici deux classes
Code:
1
2
3
|
public class Personne implements Serializable {
} |
Code:
1
2
3
4
5
6
|
public class Occupation implements Serializable{
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name="MATRICULE")
private Personne personne;
} |
Dans la classe Occupation je référence Personne
Quand je veux insérer une occurrence d'opération en faisant ceci
Code:
1
2
3
|
Personne p1 = new Personne(, , , , ,);
Occupation o1 = new Occupation("01/01/2009","30/06/2009"); |
l'enregistrement se fait correctement en mettant automatiquement null ds la référence à Personne
Mais quand je fais:
Code:
1
2
3
4
|
Personne p1 = new Personne(, , , , ,);
Occupation o1 = new Occupation("01/01/2009","30/06/2009");
o1.setPersonne(p1); |
Ds ce cas j'ai l'erreur suivante:
