After Initialize , you can send a http request using following example

public static String httpPost(String url, String jsonParam) {
        try {
            httpClient = new DefaultHttpClient();
            SSLSocketFactory socketFactory = new SSLSocketFactory(sslContext);
            Scheme sch = new Scheme(SCHEME_HTTPS, HTTPS_PORT, socketFactory);
            httpClient.getConnectionManager().getSchemeRegistry().register(sch);
            HttpPost httpPost = new HttpPost(url);
            httpPost.addHeader("Content-Type", "application/json; charset=utf-8");
            httpPost.setHeader("Accept", "application/json");
            httpPost.addHeader("charset", HTTP.UTF_8);
            httpPost.setEntity(new StringEntity(jsonParam.toString(), HTTP.UTF_8));

            logger.info("executing request " + httpPost.getRequestLine());
            logger.info("executing params " + jsonParam.toString());
            HttpResponse response = httpClient.execute(httpPost);
            HttpEntity entity = response.getEntity();
            if (entity != null ) {

                String result = EntityUtils.toString(entity,"utf-8");
                logger.info("Response content is : " + result);

                return result;
            }
        } catch (Exception e) {
            e.printStackTrace();
            logger.error(e.getMessage(), e);
        }
        return "";
    }
