Siebel 'JSON' Converter from PropertySet to JSON object and Vice Versa ?

Hi MOSC Team,

We just have upgraded our application from 8.1.1.11 Patch set 16 to latest Siebel version IP16 ( with PatchSet 3 ).

Now we need to implement RESTful API interface with some EXTERNAL system ( say Microsoft Azure) with oAuth2.0 authentication.

So,

1. Since External system accepts only JSON format objects, we need to convert SiebelMessage ( propertySet ) to JSON format object so that we can sent to external system.
2. And also need to pass in JSON MessageHeader authenticationToken and other details.
3. And once ExternalSystem will process that request, it will send back Response to Siebel in JSON format ; which again we need to convert back to SiebelMessage ( propertySet ) in order to display/consume that message.
