Java and HttpURLConnection not sending data

I'm trying to get HttpURLConnection to post a JSON string to a PHP file remotely. It's not working no matter what I do. This is my current code:

HttpURLConnection httpcon = (HttpURLConnection) ((new URL('http://domain.com/me.php').openConnection()));
                            httpcon.setDoOutput(true);
                            httpcon.setRequestProperty("Content-Type", "application/json");
                            httpcon.setRequestProperty("Accept", "application/json");
                            httpcon.setRequestMethod("POST");
                            httpcon.connect();

                            String initial = "{'out': '" + idir + prod + ".jpg', 'in': '" + item[3] + "'}";
                            byte[] outputBytes = initial.getBytes("UTF-8");

                            OutputStream os = httpcon.getOutputStream();
                            os.write(outputBytes);

                            os.close();

I know that the initial string contains data, I have run a System.out.println on it and the outputBytes variables and both have contents.

I know it's not posting because I have the PHP file set to save posted contents to a file locally. No file is ever created when running it.

I know the PHP side of things work and the server accepts posts as I can run this just fine:

$ curl -H "Accept: application/json" -H "Content-Type: application/json" -d "{'value': 7.5}" "http://domain.com/me.php"

And it works fine creating the file and writing post content to output file.

EDIT

Ok, after printing the responses I'm now getting a 401 code, unauthorized. I'm using Apache HTPASSWD authentication, but I was passing the user and pass in the URL as http://user:[email protected]/me.php. This worked from curl from the CLI, so I thought it would work here also, evidently it does not.

So how do I authenticate using HttpURLConnection?

You need to set up basic authentication. You can do it through plain Java or using Apache HttpClient.
