Hello.

We are using Java clients to two different NT servers, both running NT 4.0 with the following MQSeries software installed:

MQSeries 5.2
CSD1 Support Pack
MA0C Publish-Subscribe Support Pack

Each NT server has only one queue manager and broker.

We tested the brokers using the amqsres program provided in the Pub-Sub Support Pack, and they appear to be working fine.

When we run the Java program to register a subscriber, we get the following error, but on only one server:

--------
MQRC_RFH_ERROR (2334, X'091E')

Explanation: The message contains an MQRFH structure, but the structure is not valid.

Completion Code: MQCC_FAILED

Programmer Response: Modify the application that generated the message to ensure that it places a valid MQRFH structure in the message data.
--------

Here is a snippet of the Java code, provided by the application group -

--------
// Build the RFH header for Pub/Sub
String pubSubCmd = "";
long totalMQRFHLength = 0;

// Set the message format in MQMD
msg.format = "MQHRF ";
msg.replyToQueueName = queues[i];
msg.replyToQueueManagerName = queueManagerName;
//msg.report = MQC.MQRO_NAN;
//msg.messageType = MQC.MQMT_REQUEST;
msg.correlationId = corr_ID.getBytes();

pubSubCmd = "MQPSCommand RegSub MQPSTopic "+topics[i]+" MQPSRegOpts CorrelAsId ";

totalMQRFHLength = 32 + pubSubCmd.length();

msg.writeString("RFH ");
msg.writeInt4((int)1);
msg.writeInt4((int)totalMQRFHLength);
msg.writeInt4(2146);
msg.writeInt4(0);
msg.writeString(" ");
msg.writeInt4(0);
msg.writeString(pubSubCmd);
--------

I can't see anything wrong with the RFH parameters - and again, this code works fine on one of the machines.

Any ideas what could be causing this error?

Thanks in advance.
