question about c++ client(DeliveryMode::PERSISTENT )
I sent the topic message using persistent:
destination = session->createTopic( "TEST.FOO" );
producer = session->createProducer( destination );
producer->setDeliveryMode( DeliveryMode::PERSISTENT );
......
producer->send( message );
and recived the message with the codes:
destination = session->createTopic( "TEST.FOO" );
consumer = session->createDurableConsumer(
(Topic*)destination,"testConsumer", "");
consumer->setMessageListener( this );
but I recived nothing! I think the sending has no problem,becouse I sent the
message with c++ code(just like upsite),reviced with java client
successed!So I think there must be some problems happened in my recive
codes,Is there anyone could help me?thanks.

I guess I know your mean ,maybe it is so different to java-activemq.I had
used the java-activemq,it let me to run the consumer after sending in the
state of persistent.I had try the retroactive consumer ,but it couldn't
recive all the messages,only some of them.

If you want your consumer (even a durable one) to receive the messages, it
would have to have been registered on the topic before the message was
sent. At that point, you could kill your consumer and bring it back up and
it will get the messages it missed.
The way you have your application setup, what you'd need is a retroactive
consumer (http://activemq.apache.org/retroactive-consumer.html). This will
allow your consumer to receive messages that were sent before it came
online.

yes ,first I run the producer,after finishing the sending,I run the consumer
to recive the message.because,I thought,the message is persistent,and the
consumer is DurableConsumer ,I could recive anytime.am I right?

Is it possible that you're sending the message before you've created the
consumer?
