Answer 1

The problem is that your request is not treated as a MultiPartRequest. Do something like this:

MultipartRequest multipartRequest =  request as MultipartRequest
  if(multipartRequest){
    MultipartFile attachmentFile = multipartRequest.getFile("attachment_file".toString())
    if (attachmentFile) {
        -- copy it ---
    }
  }
