 //NewServlet.java

 public class NewServlet extends HttpServlet {
 protected void processRequest(HttpServletRequest request,HttpServletResponse response)
        throws ServletException, IOException {
    response.setContentType("text/html;charset=UTF-8");
    request.setAttribute("Cricket", "Sachin");
    RequestDispatcher rd = request.getRequestDispatcher("index.html");
    rd.forward(request, response);
}

protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    processRequest(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    processRequest(request, response);
   }
 }

//index.html

The only way I can think of would be to preprocess the html, and replace "TODO write content" with whatever it is you want to show. — Maurice Perry, Nov 29 '16 at 06:28

And what control do you have on the content of the index.html? — Maurice Perry, Nov 29 '16 at 06:57
If the file is on another server, the approach is completely different — Maurice Perry, Nov 29 '16 at 07:24

If the file index.html is on another server, you don't need to use the request's attributes because you need to do another request, and the servlet API doesn't provide what you need.

You can obtain the file's content by using a HttpURLConnection for instance. Then you need to process that content to insert your data, then write the result to the servet response.
