The request data handler handles data conversion for the WebSphere business integration system component that initiates a request:

When the integration broker is InterChange Server (ICS), the collaboration creates the request business object and sends it to the appropriate connector for request processing. |

When the integration broker is ICS, you can use an access client to initiate synchronous event processing. For more information, see Support for event processing. |
Therefore, the request data handler performs a string-to-business-object conversion on the request, converting the serialized data to a request business object. This serialized data is in the request format, which is the format that the access client or the connector's application generates as output.
The Request-Response data handler determines which data handler to invoke as its request data handler based on the RequestDataHandlerMimeType property in the child meta-object. The RequestDataHandlerMimeType property contains the MIME type that the request data handler supports. If RequestDataHandlerMimeType has not been initialized, the Request-Response data handler logs an error and generates an exception. Therefore, you must initiauses the RequestDataHandlerMimeType property.
