OIC - Convert JSON to String

Use Case: Sometimes we come to situation where we get a source json file from source system and may need to send  the json as string to target system.

Source Json:

{

"firstname": "srinanda",

"lastname":"das"

}

Target Json as string:

{

"data": "{\n  \"firstname\" : \"srinanda\",\n  \"lastname\" : \"das\'\n}"

}

Opaque.xsd:

<?xml version='1.0' encoding='UTF-8'?>

<schema targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/opaque/" xmlns="http://www.w3.org/2001/XMLSchema">

<element name="opaqueElement" type="base64Binary"/>

</schema>

Implementation steps:,

Step1:  Rest trigger configure with request and response

Step2: Write a JSON file with the inputs using Stage file.

Sample.json contains:

Step3: Map the inputs to Write fields.

Step4: Read the files to opaque using Stage file.

Opaque.xsd

Map the read opaque reference to data response with decodebase64().

The flow is like below:
