I'm running the following Java, an HttpURLConnection PUT request with JSON data that will be sent from an Android device. I'll handle any raised exceptions after this is working.

Authenticator.setDefault(new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
               return new PasswordAuthentication(nameString, pwdString.toCharArray());
               }
        });

url = new URL(myURLString);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);

urlConnection.setRequestMethod("PUT");
urlConnection.setRequestProperty("Content-Type", "application/json");

OutputStream output = null;
try {
  output = urlConnection.getOutputStream();
  output.write(jsonArray.toString().getBytes());
} finally {
  if (output != null) { output.close(); }
}

int status = ((HttpURLConnection) urlConnection).getResponseCode();
System.out.println("" + status);

urlConnection.disconnect();

I'm receiving an HTTP 500 error (internal error code), that an unexpected property is blocking the request. The JSONArray comprises JSONObjects whose keys I know are correct. The server is pretty standard, and expects HTTP PUTs with JSON bodies.

Am I missing something glaring?

Thanking you kindly in advance.
