[rabbitmq-discuss] parallel consuming from one queue

[Jan Andersson]

Hi,

Hi,
we are trying to setup something that we hoped would be pretty straight 
forward but can't seem to get it to work.
We want to consume messages from a persistent queue and use ack:s. 
However all of our attempts end in us consuming one message off the 
queue and then no one else (thread or process) can consume messages off 
the queue until that message has been ack:ed.

This is in Java, we set up one channel per thread like this:
[code]
channel = connection.createChannel();
channel.exchangeDeclare(configuration.getExchangeName(), "topic", true);
channel.queueDeclare(queueName, true); // durable queue
channel.queueBind(queueName, configuration.getExchangeName(), routingKey);
consumer = new QueueingConsumer(channel);
channel.basicConsume(queueName, false, consumer);
[/code]

The ack is done like this:
[code]
channel.basicAck(delivery.getEnvelope().getDeliveryTag(), false);
[/code]

Might be hard to answer this but if anyone could point us in the right 
direction that would be great!

thanks
Jan
