REST JSON Response

Hi,

I have a sender REST scenario, where my sender is sending the JSON request to SAP PO, I am able to take the request map it to my receiver. When I am getting the response I need to convert the payload from XML to JSON. In this conversion I see an element which I have defined as String in xml in SAP PO that gets converted to integer in JSON response.

{"orderNo":"",

"taxTransactionDocID":"",

"responseCode":500,

"responseMessage":"Please select the address from proposed addressess "

}

Here in my xml I have defined responseCode as String but the value it carries is a number. When the response goes as JSON it shows up as a number.

         <xsd:element name="responseCode" type="xsd:string" minOccurs="0"/>

Thanks in advance.
