Should a servlet container create new javax.servlet.http.HttpServlet instance for each incoming request?

Any of those help For the general case - non-distributed, multi-threaded, it is guaranteed that there will be only one instance of the servlet. From the Servlet 3.0 specification:

Can JavaScript send an HTTP request to web container Servlet?

will help you Yes, JavaScript can send POST requests to arbitrary web servers. If you have control of the servlet you can avoid all cross-site scripting restrictions by setting access-control-allow-origin properties.
AJAX is a term in the web community that refers to JavaScript + HTTP requests. I recommend this AJAX tutorial from MDN. I also recommend jQuery's AJAX library.
 * Wraps jQuery's AJAX, adds X-Domain support for IE
function xDomainAJAX (url, settings) {
  if ($.browser.msie && parseInt($.browser.version, 10) >= 8 && XDomainRequest) {
    // use ms xdr
    var xdr = new XDomainRequest();
    xdr.open(settings.type, url + '?' + $.param(settings.data));
    xdr.onprogress = function() {};
    xdr.onload = function() {
    xdr.onerror = settings.error;
  } else {
    // use jQuery ajax
    $.ajax(url, settings);

hope this fix your issue Your client should change as following. Since you are using a doPOST not doGet
String URL = "http://localhost:8080/"
String serverURL = URL + "servlet?param=" + someParam;
final URL url = new URL(serverURL)
final HttpURLConnection connection = (HttpURLConnection) url.openConnection();

final BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));


HTTP Requests Query: Can i send a video over a HTTP request? And Send back json data and images?

I think the issue was by ths following , Yes you can send video file to web-server and get response via JSON with images.
For sending video you can HTTP client retrofit which is very handy. You must use @Multipart in your API calling. Here is an example.
Call<ResultObject> uploadVideoToServer(@Part MultipartBody.Part video);
File videoFile = new File(pathToVideoFile);
RequestBody videoBody = RequestBody.create(MediaType.parse("video/*"), videoFile);
MultipartBody.Part vFile = MultipartBody.Part.createFormData("video", videoFile.getName(), videoBody);
