Hi all,
    I am an ActiveMQ newbie who has managed to get a consumer/producer
system working using topics.  I would like to know which topic has sent a
particular message, but I can't figure out how to do it.  Perhaps someone
will have mercy on this problem and shoot it, like an injured horse.

Thanks!

p.s. here is a code sample, with a lot removed for simplicity.  The
if...else is what matters to me.

---
virtual void onMessage( const Message* message ){

 <do some stuff here>

  const TextMessage* textMessage =
                dynamic_cast< const TextMessage* >( message );

  string text = textMessage->getText();

  if( message->propertyExists( "topicName" ))
        text.append( message->getStringProperty("topicName") );
  else
        text.append("nope!");
  text.append("*");

  <do some more stuff here>
}

After execution, "text" always contains "*nope!*"
