If you want to configure each HTTP message that is published to the same operation on the export to use a different WebSphere® Transformation Extender map, you must configure the message to use the WebSphere Transformation Extender data binding descriptor.
You can set the WebSphere Transformation Extender data binding descriptor on both the response and request messages for an HTTP export.
The HTTP client sending requests to the HTTP export sets the data binding descriptor in the request message header or on the URL.
Set the data binding descriptor on the request message for an HTTP export when you want to configure the messages individually.
Set the data binding descriptor on the response message using the mediation flow component for an HTTP export when you want to configure the messages individually.
If you do not need to configure messages individually, it is recommended that you use the custom properties within the binding itself to make the association with WebSphere Transformation Extender.
