Inbound channel adapter throwing "no output-channel or replyChannel header available" error


I would like to get the message from JMS and send it as HTTP request and in case of failure, enqueue it again to JMS.

I've tried using inbound-message-adapter and message-driven-channel-adapter, but it fails as I get "ChannelResolutionException: no output-channel or replyChannel header available" exception but since I do not want to reply to inbound-message-adapter, not sure why would I include a replyChannel header


    <jms:outbound-channel-adapter id="outboundJMSAdaptor" jms-template="jmsTemplate"
            channel="jmsOutChannel"
            destination="requestQueue"/>
    <int:channel id="jmsInChannel" />

    <jms:message-driven-channel-adapter
            channel="jmsInChannel" destination="requestQueue"
            connection-factory="jmsConnectionFactory" message-converter="jmsMessageConverter"/>

    <int:header-enricher input-channel="jmsInChannel" output-channel="header_enriched_request">
        <int:header name="addressId" expression="payload.getId()"/>
        <int:header name="Accept-Language" value="en_GB"/>
        <int:header name="X-Source-CountryCode" value="GB"/>

        <int:header name="Content-Type" value="application/json;charset=UTF-8"/>
    </int:header-enricher>

    <int:object-to-json-transformer input-channel="header_enriched_request"
            output-channel="update_customer_shipping_address_outbound_gateway"
            object-mapper="nonNullObjectMapper"/>

    </int:transformer>

    <int:transformer input-channel="clean_no_print_char_update_customershippingaddress" output-channel="">
        <bean class="transformer.CreateCustomerShippingAddressPostTransformer"/>
    </int:transformer>

I expect a success in a normal run, getting error

org.springframework.integration.dispatcher.AggregateMessageDeliveryException: All attempts to deliver Message to MessageHandlers failed. Multiple causes:

Also, would like to enqueue the message again to the jms queue if the http:outbound-gateway respond as null or if the 3rd party services are down.


Solution

  • <int:transformer input-channel="clean_no_print_char_update_customershippingaddress" 
            output-channel="">
    

    You can't have an empty output channel on a transformer.

    It doesn't really make sense to transform something and then just discard the transformed result but if that's what you really want to do, send it to the nullChannel

    <int:transformer input-channel="clean_no_print_char_update_customershippingaddress" 
            output-channel="nullChannel">
