dans ma partie client j'ai :
try {
Properties props = System.getProperties();
ctx = new InitialContext(props);
Object refObject = ctx.lookup(EJBNames.MANAGER_METIER_HOME); ManagerMetierHome managerMetierHome = (ManagerMetierHome) PortableRemoteObject.narrow(refObject, ManagerMetierHome.class);
ManagerMetier managerMetier = managerMetierHome.create();

Vector pivots = new Vector();

Client client = new Client();
client.setStatus("status1");
pivots.add(client);

for (int i = 0; i < pivots.size (); i++) {
BasicPivot basicPivot = (BasicPivot)pivots.elementAt(i);
System.out.println( "the status of test pivot is " + basicPivot.getStatus());
managerMetier.insertPivot(basicPivot);
}

SVP, ya qlq'un qui pe me dire q'où ca peut venir mon erreur ?
Je suis perdu...
merci
