public static Notebook getAllNotebooks(String code, String redirectUri) throws IOException, URISyntaxException{
        ClassLoader classLoader = Connection.class.getClassLoader();
        URL resource = classLoader.getResource("org/apache/http/impl/client/HttpClientBuilder.class");
        String returnUri = "https://login.live.com/oauth20_token.srf";
        HttpPost tokenRequest = new HttpPost(returnUri);
        HttpClient client = new DefaultHttpClient();//HttpClientBuilder.create().build(); //Exception: http://stackoverflow.com/questions/22330848/httpclient-example-exception-in-thread-main-java-lang-nosuchfielderror-inst

        tokenRequest.setHeader(HttpHeaders.CONTENT_TYPE, "application/x-www-form-urlencoded");
        tokenRequest.setEntity(new UrlEncodedFormEntity(Connection.getParametersForURLBody(code, redirectUri), Consts.UTF_8));

        HttpResponse tokenResponse = client.execute(tokenRequest); //Here it gets stuck
