Sending and Receiving MTOM-encoded binary data - using Synchronous Integrations from Peoplesoft system

 Hi Everyone - I have a requirement to send the attachment information to 3rd party system and receive the attachment_reference as response to store it in PeopleSoft system. This attachment_reference can be used for retrieving the attachment in future.

Currently I tried similar concept but am not able to send the message

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

<soapenv:Header/>

<soapenv:Body>

<submitLargeDocument>        

    <Document>  

         <PsftXopInclude SegmentNumber='1'/> 

    </Document>      

</submitLargeDocument>

</soapenv:Body>

</soapenv:Envelope> 

Please suggest/provide more details on same if anyone has implemented in their system
