MQSeries.net :: View topic - JMS compliant and segmentation (JMS_IBM_MQMD_MsgFlags)

I wrote a simple java program, wchich use JMS compliant api to send message to Websphere MQ:

factory = new MQQueueConnectionFactory();
factory.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP);
Connection connection = factory.createQueueConnection(..);
session = (QueueSession)connection.createSession(...);

queue = new MQQueue("...");
queue.setTargetClient(JMSC.MQJMS_CLIENT_JMS_COMPLIANT);

MessageProducer sender = session.createSender(queue);
JMSTextMessage message =(JMSTextMessage)session.createTextMessage();

message.setIntProperty("JMS_IBM_MQMD_MsgFlags",new Integer(1)); //segmentation allowed
message.setText(...);

sender.send(message,dlvrMode,priority,ttl);

My goal is to pass a big message payload, which to be divided to segments on the server. I found this constant "JMS_IBM_MQMD_MsgFlags" WMQConstants.JMB_IBM_MQMD_MsgFlags with value MQMF_SEGMENTATION_ALLOWED

However the result message is :

StrucId : 'MD ' Version : 2
Report : 0 MsgType : 8
Expiry : -1 Feedback : 0
Encoding : 273 CodedCharSetId : 1208
Format : 'MQHRF2 '
Priority : 4 Persistence : 1
....'

GroupId : X'000000000000000000000000000000000000000000000000'
MsgSeqNumber : '1'
Offset : '0'
MsgFlags : '0'
OriginalLength : '-1'

This property seem to be not taken into account. Could somebody advice, what else should be set ?
Thank you very much !
