Activemq-cpp request-response

[LeBro <tz...@gmx.de>]

I started to work with Activemq-cpp and used the asychronous client that is
available as example. But now I want to implement a request-response, i.e.
the producer starts SENDINGa message to the consumer and WAITS for the
response. The consumer GETS the message, CHANGES it and SENDS back to the
producer. The consumer has a receive option, but I have no idea how to
configure both for request-response, especially the producer.

I appriciate any help. Thx in advance.

Simple answer, deactivate nummessages.

It works. Thank you. 

Now there is another question: How to set up a consumer waiting forever? The
timelimit can be set by waitmillis=-1, but what about deactivating the
shutdown after a predefined number of messages? 

Thanks in advance.

The CMS client is a porting of JMS to C++ and as such the examples 
<http://activemq.apache.org/how-should-i-implement-request-response-with-jms.html> 
that explain how to do JMS Request / Response are easy to port to the 
C++ client.

The basic structure is that on the request side the client must create a 
producer to send the request and a consumer to process the response. The 
consumer should be created and be listening on the target response 
destination prior to sending the request. On the responder side a 
consumer is created that reads from the request Queue and does its work 
and when done it creates a producer that sends a response to the 
destination specified in the ReplyTo property of the incoming request.
