QMF2 creating queues

[fadams <fr...@blueyonder.co.uk>]

I'm playing with QMF2 from JMS and I seem to be able to create queues using
the following:

	MapMessage request = requestResponseSession.createMapMessage();
	request.setJMSReplyTo(responseQueue);
	request.setStringProperty("x-amqp-0-10.app-id", "qmf2");
	request.setStringProperty("qmf.opcode", "_method_request");

	Map objectId = new HashMap();
	objectId.put("_object_name", "org.apache.qpid.broker:broker:amqp-broker");
	request.setObject("_object_id", objectId);

	request.setString("_method_name", "create");

	Map arguments = new HashMap();
	arguments.put("type", "queue");
	arguments.put("name", name);
	request.setObject("_arguments", arguments);

	requestProducer.send(request);

	Message response = responseConsumer.receive(10*1000);

	if (response != null) {
etc....

This seems to work fine with the 0.10 broker, however with the 0.8 broker
(both C++) I get the following exception when I decode the response...

"No object found with
ID=0-0-0--0(org.apache.qpid.broker:broker:amqp-broker)"

Is is possible to create queues etc. at runtime with the 0.8 broker??

well clearly it is because qpid-config works fine and queues get created
fine from address strings, but I thought my snippet above was the correct
way to do this with the QMF2 protocol

Any ideas???

Yes, but not with QMF. The create/delete methods were added to the 
brokers schema in 0.10.

qpid-config uses the queue-declare etc commands in the underlying 0-10 
protocol for creating queues it only uses QF for querying existing 
queues etc (as this is not supported by the underlying protocol)
