I was able to achieve a similar output by converting the file to string/byte[] data and sending it via REST.

My implementation was in Java and the steps used is outline below

  1. Convert the file on disk to byte[] array (apache common-io can convert the file to byte[] in easy step. Try the IOUtils class)
  2. Encoded the byte[] as String (apache common-codec was used for the encoding)
  3. Wrapped the string data in a model class
  4. Converted the model class to json format (GSON was used for the conversion)
  5. Sent the json data over to the server
  6. The server application reversed the process, and the file was available on the server

A rest service isn't the right way for what you want. The input for this kind of services are HTTP request attributes or some kind of pushed data. Maybe it's possible to implement a file upload but it's not typical. For restful services is also common to tell your service how to handle the requested resource via the used request method (GET, POST, PUT, DELETE) The response of rest services is normally some kind of structured text output - for instance json.

All in all rest services seems to me not the way to implement your desired scenario. What about a normal cgi or servlet solution?
