WHINT JSON Converter Adapter Module



This Adapter Module is able to convert a JSON message into XML and vice versa.


  • By default all values are shown as strings. If boolean and number values should be handled without quotes, you can add a generic or a specific conversion
  • The root tag can be removed if required


  • a root node can be added (if not existing in the JSON) to the XML document
  • an XML namespace can be added (to an existing or a configured) root node
  • invalid XML element names are being escaped with an underscore, e.g.
    • “64×64” => <_64x64>
    • “start&stop” => <start_stop>


  • Deploy the SCA/EAR file provided by Whitepaper InterfaceDesign using NWDS/JSPM/SUM/Telnet

A JSON Message is sent from an AWS SQS Queue, converted into XML and forwarded to an SFTP Server.

  1. Send JSON Message (here manually) into an AWS SQS Queue:

2. Channel Configuration (AWS_SQS Sender Channel)

3. The WHINT AWS SQS Adapter on SAP Process Orchestration is picking up the message and converting into XML:

4. The XML namespace is shown in the Message Monitor:

Example for specific XML to JSON Field Value Conversion:









{ “Field1”: “StringValue”, “Field2”: true, “Field3”: 100, “Field4”: “AnotherString” }
