Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to KiaEntites.Test$Item_Ledger_Entry
l'exception est capturé dans la partie jaune

voila mon code:

import java.util.Iterator;
import java.util.List;

import javax.naming.Context;
import javax.naming.InitialContext;
import KiaEntites.*;
import Kia.sessionFacade.*;


public class testListeVoiture {
public static void main(String []args){
try {
Context context = new InitialContext();
ListerStockInterface stock = (ListerStockInterface)context.lookup("ListeVoitureStock/remote");
List<Test$Item_Ledger_Entry> produits = stock.listerTousLesVoitures();
for (Iterator i = produits.iterator(); i.hasNext();)
System.out.println(produits.get(1).getDescription());





} catch (javax.naming.NamingException ne) {
ne.printStackTrace();
}
}
}
