Help regarding reading multiple response

I am new to Apache Camel. I need your help w.r.t below scenario.

I am using
template.requestBody("wmq:queue:QUEUENAME?replyTo=QUEUENAME&useMessageIDAsCorrelationID=true&replyToType=Exclusive",reqXML)
to send a request and read a response. 

But I have a scenario where I send a request and get 2 responses at the same
Reply Queue. Is there a way I can have this feature using Apache Camel.

Can you please help me regarding this case.

Regards,
Jagadeesh Sripada

It looks like the REQUEST QUEUENAME consumer doesn't know about the replyTo property of the message.
BTW, I think it could be more easy for you to handle the multiple response with lower level JMS API with the correlation id.

Hi Willem Jiang,

Thanks for the reply. I started using the ConsumerTemplate and I am still
not getting the response back, below is the snippet that I have used.

ProducerTemplate camelTemplate = context.getBean("camelTemplate",
ProducerTemplate.class);
ConsumerTemplate consumerTemplate = context.getBean("consumerTemplate",
ConsumerTemplate.class);
camelTemplate.sendBody("wmq:queue:[REQUEST
QUEUENAME]?useMessageIDAsCorrelationID=true", xe80Req);
String resp = consumerTemplate.receiveBody("wmq:queue:[REPLY
QUEUENAME]").toString();

My camel-context.xml is as following
<camel:camelContext id="camel-client">
	<camel:template id="camelTemplate" />
	<camel:consumerTemplate id="consumerTemplate"/>
</camel:camelContext>

I am not able to get the response

Thanks,
Jagadeesh Sripada

Current camel-jms component doesn't support to get two responses at the same time.
I think you need to do the Correlation yourself, if you use ConsumerTemplate[1] to receive the response in the replay queue.
