Answer 1

You should not send it as a JSON string, but as a JS object. Change

 data: JSON.stringify(dataRequestObject), 

by

 data: dataRequestObject, 

and access the values ​​in the servlet in the usual way with the keys present in the JS object

 String mark = request.getParameter("mark"); String subject = request.getParameter("subject"); String language = request.getParameter("language"); String author = request.getParameter("author"); // ... 

---

Please note that your servlet must run in the same domain, otherwise you will end up in the Same origin rule . If it really works in the same domain, I would not hard code the domain in JS code, since it makes your code completely unsportsmanlike. Therefore replace

 url: 'http://localhost:8090/SampleServlet1/serv' 

by

 url: '/SampleServlet1/serv' 

or

 url: 'serv' 

.
