PO404 Error when sending HTTP request through java

Body
copied!<p>I seem to be getting a 404 error when sending a http post to a sinatra server. I am trying to make the server page the text I send to it, here's my code I think it may be something wrong with my server but I'm not sure:</p> <pre><code>private void sendInfo() throws Exception { //make the string and URL String url = "http://localhost"; URL obj = new URL(url); HttpsURLConnection con = (HttpsURLConnection) obj.openConnection(); //add request header con.setRequestMethod("POST"); con.setRequestProperty("User-Agent", USER_AGENT); con.setRequestProperty("Accept-Language", "en-US,en;q=0.5"); String urlParameters = "sn=C02G8416DRJM&cn=&locale=&caller=&num=12345"; //send post con.setDoOutput(true); DataOutputStream wr = new DataOutputStream(con.getOutputStream()); wr.writeBytes(urlParameters); wr.flush(); wr.close(); int responseCode = con.getResponseCode(); System.out.println("\nSending 'post' request to url: " + url); System.out.println("Post parameters : " + urlParameters); System.out.println("Response code: " + responseCode); BufferedReader in = new BufferedReader( new InputStreamReader(con.getInputStream())); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); //print result System.out.println(response.toString()); } </code></pre> <p>and here is the sinatra server (ruby):</p> <pre><code>require 'sinatra' get '/' do 'hello mate' end get '/boo' do 'trololo' end </code></pre>
