Hi All,
Iâ€™ve been straggling with this for couple of days, I hope some one will shed some light on this. We have Java client connecting to our MQ server 7.x over a VPN. (All Windows platform). When their code issue a put message all goes as expected. When receiving messages, they get MQJE001: Completion Code '2', Reason '2195' (written by the get() method). Then they receive the message in full with the
The following (RFH <mqps><Top>TOPIC.BR.PCSQ01.0001</Top></mqps>) , which is part of the message â€˜Named Propertiesâ€™. I run the same code over a LAN with no issues. So I suspected communication issues and indeed it was there in the log: An error occurred receiving data from 10 (10.68.24.150) over TCP/IP. This may be due to a communications failure.
We will look into the network. But how is the communications failure causes a message property to be part of the message Payload?

Here is the get method:

private String receiveMessage()
{
MQQueue aQueue;
String aMessage = null;
MQMessage aTextMessage = new MQMessage();
aTextMessage.format = MQC.MQFMT_STRING;
aTextMessage.characterSet = 1208;
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options = MQC.MQGMO_WAIT;
gmo.waitInterval = timeout;
try
{
aQueue = (MQQueue)getMqConnection().accessQueue(receivingqueue, MQC.MQOO_INPUT_AS_Q_DEF);
aQueue.get(aTextMessage, gmo);
aMessage = aTextMessage.readStringOfCharLength(aTextMessage.getMessageLength());
aQueue.close();
if (aMessage == null)
{
// Timeout and no message received.
System.out.println("Timeout out while waiting for response");
}
}
catch (IOException ioe)
{
ioe.printStackTrace();
}
catch (MQException e)
{
e.printStackTrace();
}
return aMessage;
}
