Receives always null message while trying to read a message from MQ

I try to receive the message from the MQ. I can able to see the messages in the MQ Explorer. But i cant able to get the messages. It always return null. But i can able to drop message to the Queue.

The code is here.

 MQQueueConnectionFactory cf = new MQQueueConnectionFactory();
    cf.setHostName("localhost");
    cf.setPort(1415);

    cf.setIntProperty(WMQConstants.WMQ_CONNECTION_MODE, WMQConstants.WMQ_CM_CLIENT);

    cf.setQueueManager("TEST");
    cf.setChannel("TEST.CHANNEL");


    MQQueueConnection connection = (MQQueueConnection)cf.createQueueConnection("mqusr","q@789945");

    MQQueueSession session = (MQQueueSession) connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
    MQQueue replyQueue = (MQQueue) session.createQueue("queue:///TEST.REPLY.QUEUE");
    MQQueueReceiver receiver = (MQQueueReceiver) session.createReceiver(replyQueue);

    TextMessage receivedMessage = (TextMessage) receiver.receive(10000);
   String reponseMessage = receivedMessage != null ? receivedMessage.toString() : "";

To receive the message you need to issue connection.start() before doing a receive.receive(10000) –
