Copy synchronous response to separate asynchronous mapping

Hi Folks

I have a integration scenario challenge, that I was sure could be implemented technically. But after searching the communicty and google in general, I still havent found a solution. Therefore I would like to hear if any of you have any input to this challenge..

The requirement is pretty simple: System A make a synchronous request to System B. Response should be synchronous returned to System A, but System C should get a asynchronous copy of the response.

Illustrated like this:

However I cant find any way of copying the response and forward it to the asynchronous integration.

Anyone having any suggestions to how this can be achieved.. (Or if it is possible at all)

Thanks a lot for your input.

/Chris

    You can also split it into two interfaces, instead of one. this can save the System A's waiting time.

    System A to System B ====> sync scenario

    and create one more async scenario

    System A to System C =====> Async Scenario

    In the sender proxy coding(A), once you get the response from system B, trigger 2nd asynchronous interface.

    • This will add additional failover points apart from connectivity issue. Like Supoose your first scenario is successful and you second scenario is failed. So data mismatch in system A and C.

      If you handle that in the response message then if mapping will be successful means if system C will be updated then there are very less chances to fail updation of system A with the response as it is single sync scenario. Though there are chances of failure here as well but definitely failover points and pipeline steps will be less.

    Thanks for the responses so far.. It is very much appreciated that you take your time to help out.

    But I am still wondering if there is any adapter modules to be used. Like for example when creating an async/sync bridge with the OneWayResponseBean. I would like a CopyPayloadAndRedirectToThisInterfaceAsync Module :-)

    Cheers

    Hi Chris!

    Maybe it worth trying to develop custom adapter module that creates a copy of response message and separately sends it to messaging system?

    Hi Chris,

    I believe the best way is to create one synchronous scenario from system A to system B and in the response message mapping doing one look up to the system C to push the response. Now the type of look up can be RFC look up/jdbc look up/soap look up/REST look up as per system type C.

    Thanks,

    Apu
