<p class=MsoNormal>So if declare_ok always refers to a new queue, we

<p class=MsoNormal>Actually, your code is creating a new queue, so in your
example, the declare_ok will always refer to a new queue.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>But if you declare a queue that already exists (which a
producer has already populated with messages), you'll get back the message
count. Give a name to your queue and have the producer and consumer use the
same name.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<div>
<p class=MsoNormal>If you attach your consumer to a new queue (which you're
doing by creating an anonymous queue) the message count will obviously be zero
because nothing has put messages in it yet.<o:p></o:p></p>
