NAS not answering the handler function “MessageReceived”

jlg

Does somebody help me ?
Problem is that MessageReceived fonction is never activated.
I'de checked parameters (UTF-8, authorizations, queues).
This is my code :
OBJECT Codeunit 50017 WebServices
{
OBJECT-PROPERTIES
{
Date=23.10.08;
Time=17:01:11;
Modified=Yes;
Version List=WEBSERVICES;
}
PROPERTIES
{
SingleInstance=Yes;
OnRun=
BEGIN
BEGIN

MESSAGE('BEGIN OK');

IF ISCLEAR(CC2) THEN
IF NOT CREATE(CC2) THEN
ERROR('Erreur lors de la cr‚ation NavisionComponent CC2');
IF ISCLEAR(MQBus) THEN
IF NOT CREATE(MQBus) THEN
ERROR('Erreur lors de la cr‚ation QueueBus MQBus');
CC2.AddBusAdapter(MQBus,1);
MQBus.OpenReceiveQueue('.\private$\toNavision',0,0);
MQBus.OpenReplyQueue('.\private$\fromNavision',0,0);

MESSAGE('Queues OPEN OK');
END;
END;

}
