public String updateCommande() {
Object[] cobj = checkbox1.getSelectedValues();
int size = cobj.length;
System.out.println(size+"\n");
Set<Exigence> exigences = null;
int i = 0;
for (i = 0; i < size; i++) {
System.out.println("cobj" + cobj[i]);
String l = (String) cobj[i];
Exigence exigence = exigenceService.findByIdExigence(l);
System.out.println(exigence.getIntitule());
exigence.setCommande(currentCommande);
}
currentCommande.setDateCreation(new Date());
commandeService.saveCommande(currentCommande);} |

il m'indique que le probleme se trouve au niveau de la ligne : System.out.println(exigence.getIntitule());
sachant que dans mes classes entités j'ai changé tout les fetch j'ai mi "EAGER" au lieu de "LAZY" (fetch = FetchType.EAGER ), et j'ai un filter dans mon fichier web.xml
Code:
1
2
3
4
5
|
<filter>
<filter-name>hibernateSessionFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter> |
merci d'avance pour votre aide
