The response data handler handles data conversion for the WebSphere business integration system component that responds to a request:
Therefore, the response data handler performs a business-object-to-string conversion on the response, converting the response business object to serialized data. This serialized data is in the response format, which is the format that the access client or the connector's application accepts as input.
The Request-Response data handler determines which data handler to invoke as its response data handler based on the ResponseDataHandlerMimeType property in the child meta-object. The ResponseDataHandlerMimeType property contains the MIME type that the response data handler supports. If ResponseDataHandlerMimeType has not been initialized, the Request-Response data handler logs an error and generates an exception. Therefore, you must initiauses the ResponseDataHandlerMimeType property.
