Configuring the Sync/Async Bridge in the Receiver JMS AdapterLocate this document in the navigation structure

Use

You can specify modules for the sync/async bridge in the module processor in the receiver JMS adapter. You can use a sync/async bridge to connect a synchronous system to an asynchronous system.

The synchronous request is converted to an asynchronous request in the module processor and sent.

The asynchronous system sends a response to a sender adapter. In the module processor of the sender adapter, this response is forwarded to the module processor of the original receiver adapter, where it is sent as a synchronous response of the waiting synchronous request.

The XI message ID of the request message and the XI conversation ID (or XI RefToMessage ID) of the response message are correlated using the JMS correlation ID.

Procedure

Define Correlation Settings in the Adapter Configuration

  1. Create a receiver JMS adapter.

    More information: Configuring the Receiver JMS Adapter

  2. Under Correlation Settings, select 
    XI Message ID
    as the JMSCorrelationID.
  3. Create a sender JMS adapter.

    More information: Configuring the Sender JMS Adapter

  4. Under Correlation Settings, select 
    JMS Correlation ID
    as the XIConversationID.

    Both adapters must run on the same Adapter Engine.

Add Modules in the Module Processor for the Receiver JMS Adapter

  1. For the receiver JMS adapter, add the AF_Modules/RequestOnewayBean module before the SAP XI JMS Adapter/ConvertMessageToBinary module in the Processing Sequence.
  2. In the Module Configuration, add the passThrough parameter with the value true to the AF_Modules/RequestOnewayBean module.
  3. Add the AF_Modules/WaitResponseBean module after the SAP XI JMS Adapter/SendBinarytoXIJMSService module.

Add Modules in the Module Processor for the Sender JMS Adapter

  1. For the sender JMS adapter, delete the CallSapAdaptermodule in the Processing Sequence.
  2. Add the AF_Modules/NotifyResponseBean module instead of the CallSapAdaptermodule.

Create Collaboration Agreements

  1. Create the following collaboration agreements:
    • A receiver agreement for the receiver JMS adapter
    • A sender agreement for the asynchronous response message
