Hi
I want to upload file using restful service

This is my code to send file to rest service


MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
FileBody bin = new FileBody(f);
FormBodyPart bodypart = new FormBodyPart("file", bin);
reqEntity.addPart(bodypart);

HttpClient httpclient = new DefaultHttpClient();
          HttpPost httppost = new HttpPost(url + args);
          httppost.setEntity(reqEntity);
          StringBuilder str = null;
          
          HttpResponse response = httpclient.execute(httppost);
          


But how can i retrive at server side in restful service using plsql?
