Nathan Mittler updated AMQCPP-64:
---------------------------------

      Description: 
Hi 

I am using the activemq-cpp cms api 1.0 release. The problem I am facing is like this- 
My producer sends a message to the consumer and a message should be sent from the receiving
end as a reply after this - consider a situation where a loginRequest message has been sent
and now a loginReply message should be sent from the receiving end. 

Attached is a sample main that can reproduce the problem I am facing - I have modified the
sample helloproducer helloconsumer code available at 
http://activemq.org/site/activemq-cpp-client.html  
to reproduce my problem so that its easier for you to see. Please see attached cpp file =
DestProbs.cpp.

If you execute this piece of code you will see the output as in the attached image file (see
attachments = DestinationProblem.JPG)

This is what the code does 
producer lets call it xxx sends a "Hello world! from thread xxxx" to the consumer 
consumer lets call it yyy receives the message and displays it 
this is the normal behavior as given in the example on http://activemq.org/site/activemq-cpp-client.html

Following extra needs to be done now 
from yyy a reply should go back to xxx ... for this i registered a producer at yyy by creating
a topic using the message->getCMSReplyTo() and then replying back to that destination.


The mismatch can be easily see by doing a bstat .... when I created the consumer yyy initially
it created a topic by name say ABCDEFGH (which is a random id) and later on when I used the
message->getCMSReplyTo() to create a topic the topic was registered with the name /topic/ABCDEFGH
..... the additional /topic/ that has got added is doing a mess up here and the replies from
yyy to xxx are not reaching xxx (getting enqueued and not dequeued) ... 

the /topic/ gets added due to the following statement in HelloWorldProducer - run method 
message->setCMSReplyTo(replyTopic->toProviderString()); 
here the toProviderString method adds it actually ... if you replace this method with just
the toString() method ... you will get a stomp exception saying that destinations should start
with either /topic/ or /queue/ 

Can somebody make this code work please. 

For every message sent by the producer to consumer "Hello world! from thread xxxx" there should
be a reply coming back as "Thank you for Hello World !!!" 

Please help me urgently here. 

Thank you in advance
