    copied!<p>I'm sending a message built with google's protocol buffer from and android device using this code:</p> <pre><code>// Set up the HttpClient HttpClient client = new DefaultHttpClient(); String url = "http://192.168.2.103:8888/sdroidmarshal"; HttpPost postRequest = new HttpPost(url); // Create the content for the message AbstractContentBody[] parts = new AbstractContentBody[1]; InputStream ins = new ByteArrayInputStream(offers.build().toByteArray()); parts[0] = new InputStreamBody(ins, "sdroidmsg"); // Add the content to the message MultipartEntity requestContent = new MultipartEntity(); requestContent.addPart("message", parts[0]); // Send! postRequest.setEntity(requestContent); client.execute(postRequest); try { ResponseHandler&lt;String&gt; responseHandler = new BasicResponseHandler(); String responseBody = client.execute(postRequest, responseHandler); } catch (Throwable t) { } </code></pre> <p>Eventually this code will actually be sending more than one part...</p> <p>I have a servlet running on Google's app engine that receives this post request and at the moment only has the following code:</p> <pre><code> protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { super.doPost(req, resp); try { ServletFileUpload upload = new ServletFileUpload(); resp.setContentType("text/plain"); FileItemIterator iterator = upload.getItemIterator(req); while (iterator.hasNext()) { FileItemStream item = iterator.next(); InputStream stream = item.openStream(); if (item.isFormField()) { log.warning("Got a form field: " + item.getFieldName()); } else { log.warning("Got an uploaded file: " + item.getFieldName() + ", name = " + item.getName()); } } } catch (Exception ex) { throw new ServletException(ex); } } </code></pre> <p>Obviously the server doesn't do very much right now! But I have noticed that it seems to receive two parts both called "message" and file "sdroidmsg", which I really don't understand. Surely it should only receive this once? I thought perhaps that sdroidmsg might be being split into two part because of size, but that is a complete guess, I don't really know the inner working of what's happening behind the scenes. Could anyway explain why this is happening? I can post more code if required.</p>
