Dear Rabbiters,<br>
<br>
i'm running into a problem getting node.js to talk to scala over<br>
rabbitmq. i'm using the node-amqp package with node.js. i installed it<br>
using npm install amqp. i'm using the java client for rabbitmq 2.5.1 on<br>
the scala side. i've successfully gotten scala to talk to scala<br>
and node.js to talk to node.js. However, when i attempt to get node.js<br>
to talk to scala there appears to be a disagreement regarding<br>
queue declaration. Thus, if i fire up node.js first and look at the<br>
queue it creates with the rabbitmq management plugin i see<br>
<br>
<br>
<br>
node-simple-direct_queue<br></div>

<br>
So this looks like a transient autodelete queue.<div class="im"><br>
<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
i then attempt to accomplish a connection from the scala side (with code<br>
that works on scala-to-scala) and i see an exception when the code calls<br>
the queueDeclare method.<br>
<br>
channel.exchangeDeclare( exQNameRoot, "direct" )<br>
//channel.queueDeclare(qname, true, false, false, null);<br>
channel.queueDeclare(qname, true, false, true, null); // <-- here we<br>
throw an exception<br>

<br></div>
And here you are declaring a durable autodelete queue. That's probably your problem.<div class="im"><br>

...but you can unwrap this exception and check, or look in the broker logs to see what it's complaining about.<br>
