Re: Attemp to send message to activemq temporary queue using producerTemplate: InvalidMetadataException

[Willem Jiang]

Hi

I think this is bug of camel-jms, I just fill a JIRA[1] for it.

I'm running apache-servicemix 4.1.0-psc-01-00RC1, using the included version
of ActiveMQ and Camel.  I have some code that's receiving a message from an
ActiveMQ queue, then sending a message to the temporary queue it got from

JMSReplyTo.

        @EndpointInject
        private ProducerTemplate producerTemplate = null;


        @Consume(uri = "subscriptionRequestEndpoint")
        public synchronized void processSubscriptionRequest(
                        @Header("JMSReplyTo") Destination jmsReplyTo,
                        @Body SubscriptionManagerRegister registrationMessage) {
                try {
                        log.info("got registration request client name = "
                                        + registrationMessage.getClientName() + " 
jmsReplyTo = "
                                        + jmsReplyTo);
                        tempQueueList.add((TemporaryQueue) jmsReplyTo);
                        publishMessageToSubscriber((TemporaryQueue) jmsReplyTo, 
"hello");
                } catch (Exception e) {
                        log.warn("processSubscriptionRequest", e);
                }
        }

        public synchronized void publishMessageToSubscriber(
                        TemporaryQueue temporaryQueue, Serializable message) {
                try {
                        final String endpointName = "activemq:temp:queue:"
                                        + temporaryQueue.getQueueName();
                        producerTemplate.sendBody(endpointName, message);
                } catch (Exception e) {
                        log.warn("publishMessageToSubscriber", e);
                }
        }

When the producerTemplate.sendBody call runs, I get the following exception. Is this a camel bug or am I doing something wrong?
