activemq-cpp persistant problem

[amq user]

I couldn't get activemq-cpp persistent working. I can get java client
working as expected.

from the example code:

           producer->setDeliveryMode( DeliveryMode::PERSISTANT );

If I stop the activemq and start it again, all messages I send would be
gone.
But if I use java client: (from example code)

       if (durable) {
           producer.setDeliveryMode(DeliveryMode.PERSISTENT);
       }

then I can retrieve the message after activemq restarted.

Anyone had similar problem? Any idea?

Thanks
