The following example uses the Message Translator EIP to do a transformation on the failed exchange before it is moved to the JMS dead letter queue: Here we only store the original cause error message in the transform. See also the requestTimeoutCheckerInterval option. The JmsProducer detects the InOut and provides a JMSReplyTo header with the reply destination to be used. The JmsProducer behaves as follows, depending on configuration: Camel will expect a reply, set a temporary JMSReplyTo, and after sending the message, it will start to listen for the reply message on the temporary queue. As otherwise each node in the cluster may pickup messages which was intended as a reply on another node. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.

Some components only have a few options, and others may have many. 1. Lets get started: Create class CrunchifyMapToJsonObject.java. Allows to process reply messages concurrently using concurrent message listeners in use. By default Camel assumes the queue is shared when using fixed reply queues, and therefore it uses a JMSSelector to only pickup the expected reply messages (eg based on the JMSCorrelationID).

Notice: That using Shared reply queues may not work as well with concurrent listeners, so use this option with care. Messages will only going to lower priority consumers when the high priority consumers do not have credit available to consume the message, or those high priority consumers have declined to accept the message (for instance because it does not meet the criteria of any selectors associated with the consumer).
