Return Address

Camel supports the Return Address from the EIP patterns .

How does a replier know where to send the reply?

The request message should contain a Return Address that indicates where to send the reply message.

Camel supports Return Address by messaging Components that provides this functionality such as the JMS component via the JMSReplyTo header.

Example

In the example below we send a message to the JMS cheese queue using InOut mode, this means that Camel will automatically configure the JMSReplyTo header with a temporary queue as the Return Address.

Java
XML
YAML

from("direct:foo")
  .to(ExchangePattern.InOut, "jms:queue:cheese");

<route>
    <from uri="direct:foo"/>
    <to pattern="InOut" uri="jms:queue:cheese"/>
</route>

- route:
    from:
      uri: direct:foo
      steps:
        - to:
            uri: jms:queue:cheese
            pattern: InOut

You can also specify a named reply queue with the replyTo option (instead of a temporary queue). When doing so then InOut mode is implied:

Java
XML
YAML

from("direct:foo")
  .to("jms:queue:cheese?replyTo=myReplyQueue");

<route>
    <from uri="direct:foo"/>
    <to uri="jms:queue:cheese?replyTo=myReplyQueue"/>
</route>

- route:
    from:
      uri: direct:foo
      steps:
        - to:
            uri: jms:queue:cheese
            parameters:
              replyTo: myReplyQueue
