[#2]

Here I am providing the small snippet:

String uri=livyServerModel.getUrl()+"/sessions";

JSONObject jsonObject= getPOSTRequestResponse(request,uri);

/**/

getgetPOSTRequestResponse:

URL url = new URL(uri);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setDoOutput(true);

conn.setRequestMethod("POST");

conn.setRequestProperty("Content-Type", "application/json");

OutputStream os = conn.getOutputStream();

os.write(request.toString().getBytes());

os.flush();

BufferedReader br = new BufferedReader(new InputStreamReader(

(conn.getInputStream())));

String output;

while ((output = br.readLine()) != null) {

response = output;

}

conn.disconnect();
