[rabbitmq-discuss] Alternate Exchange Configuration Issue

Mon Jan 24 19:33:16 GMT 2011

Hi ,

Am experiencing trouble when configuring alternate exchange for my
broker. I am following the docs present in rabbitmq site. The error am
getting is

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error;
reason:
{#method<channel.close>(reply-code=406,reply-text=PRECONDITION_FAILED -
inequivalent arg 'alternate-exchange' for exchange 'exchange' in vhost
'/':  required {longstr,<<97,101>>}, received
undefined,class-id=40,method-id=10),null,""}

Caught: com.rabbitmq.client.AlreadyClosedException: clean connection
shutdown; reason: Attempt to use closed channel

As you can see in the Stack Trace, am defining alternate exchange and
looks like it does not like it. This is my rfrence from RabbitMQ Site

Map<String, Object> args = new HashMap<String, Object>();

args.put("alternate-exchange", "my-ae");

channel.exchangeDeclare("my-direct", "direct", false, false, args);

channel.exchangeDeclare("my-ae", "fanout");

channel.queueDeclare("routed");

channel.queueBind("routed", "my-direct", "key1");

channel.queueDeclare("unrouted");

channel.queueBind("unrouted", "my-ae", "");
