[Question] Exchange Pattern config

[hguerrero]

Where can we configure the exchangePattern, for example, if I want to use it for InOnly in my JMS routes?

I believe it is something like that:

My issue is that I need to change the exchange pattern only for one step rather than the complete route. My route is an HTTP endpoint that sends a fire-and-forget message to a JMS topic. Still, the HTTP call needs to send back a response.

Something like that should work:

- rest:
    id: rest-f1bf
    post:
      - id: post-1860
        to: direct:derect1
- route:
    id: derect1
    from:
      uri: direct:derect1
      id: from-51ad
      steps:
        - to:
            uri: kamelet:jms-apache-artemis-sink
            id: to-d48b
            parameters:
              destinationType: queue
              destinationName: queue1
              brokerURL: tcp://my-host:61616
        - setBody:
            id: setBody-ec18
            expression:
              constant:
                expression: RESPONSE
                id: constant-99fa

Yes Marat is correct, you then set ExchangePattern = InOnly for the "To" EIP where you call the JMS queue.
