A. Use Oracle Service Bus or BPEL Process Manager and utilize the REST binding that is available for both. The REST binding will automatically translate a REST payload from JSON or XML to SOAP/XML for processing in the middleware layer.

B. Use a BPEL process with a REST binding and utilize the nXSD activity to translate the native JSON payload to XML for processing.

C. Oracle Service Bus must be used. An HTTP proxy service is created and a pipeline is added with a conditional branch for each HTTP verb that the interface will serve. If there is any non-XML payload, such as JSON, an external parser service must be used to translate it to XML.

D. Use the HTTP transport in Oracle Service Bus for the REST interaction and use nXSD to translate the JSON payload to XML for processing.
