Here we will see

  • Using SAP-PI UDF (Java), we consume SharePoint REST to write a File into SharePoint.
  • A business requirement, where employee’s pending item counts need to be updated in SharePoint in file format.
  • Employee’s Pending Count will be fetched from one system’s REST service and resulted string will be posted into a file format in SharePoint.
  • Fetching Employee’s Pending Count via respective REST service will be handled in separate UDF-1 and its result will be supplied to this SharePoint UDF-2.
  • Here we focus on java coding of “SharePoint UDF-2”
  • To access SharePoint, we need to fetch AccessToken first which can be get by following link help:



  • Here we try to write a constant string into SharePoint in FileFormat
  • This constant string can be replaced by desired strings like employee’s pendingCount data as described in Overview section
  • AccessToken required for SharePoint authentication which can be found from above mentioned link.
  url: http://<siteUrl>/_api/web/GetFolderByServerRelativeUrl('/<FolderName>')/Files/add(url='<fileName>',overwrite=true)
  method: POST
  body: "Contents of file"
  Authorization  : "Bearer " + accessToken
  X-RequestDigest: form digest value
  content-length :length of post body				
  String siteUrl = "https://<hostName>"; 
  String wsUrl = siteUrl + "/_api/web/GetFolderByServerRelativeUrl('Shared%20Documents')/Files/add(url='File1.txt',overwrite=true)";				
  String request = "Create a File with raw string !!!";
  //Create HttpURLConnection
  URL url = new URL(wsUrl);
  URLConnection connection = url.openConnection();
  HttpURLConnection httpConn = (HttpURLConnection) connection;
  //Set Header
  httpConn.setRequestProperty("Authorization", "Bearer " + accessToken);						
  //Send Request
  DataOutputStream wr = new DataOutputStream(httpConn.getOutputStream ());				
  //Read the response.
  responseStr = "HTTP ResponseCode: " + httpConn.getResponseCode() + " "+  httpConn.getResponseMessage();

      Dear Former Member

      Sorry for delayed response, I was too much busy in my current project….

      This is working in PI 7.1 and PO 7.5.

      But I’ve not tried this in XI version, it should work because this is UDF logic to call REST service with POST method, jre1.4 too is supported with this piece of code.


      Thanks & Regards
