[jira] Commented: (AMQCPP-64) Inconsistency in topic names when
creating topics
[ https://issues.apache.org/activemq/browse/AMQCPP-64?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_38445 ]
Lalit Nagpal commented on AMQCPP-64:
------------------------------------
Hi Nathan-
Did you try doing it ... and running the code again ... it throws an exception saying that topics should start with a /topic/ or a /queue/ ... find a screen shot attached for it ....
I had tested this too earlier ... this exception made me use toProviderString() .....
please read the contents posted earlier by me which had this statement
"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/ "
I am reattaching the entire code for your reference using toString() method this time instead of toProviderString() ... you can execute it and see it for yourself.
Thanks

> 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
