NewFile.html

<script>
    $(document).on("click", "#somebutton", function() {
        if (navigator.geolocation) {

            navigator.geolocation.watchPosition(showPosition);
        } else {
            x.innerHTML = "Geolocation is not supported by this browser.";
        }

        function showPosition(position) {
            console.log(position)

            var params = {
                lat : position.coords.latitude,
                lng : position.coords.longittude
            };

            $.get("someservlet", $.param(params), function(responseText) { // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response text...
                // Locate HTML DOM element with ID "somediv" and set its text content with the response text.
            });

        }

    });
</script>

servlet.java

public class servlet extends HttpServlet {
    private static final long serialVersionUID = 1L;



    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String text = "some text";
       String params= request.getParameter("params");
        System.out.println(params);
    }

}

Renato :

Your Servlet:

public class servlet extends HttpServlet {
    private static final long serialVersionUID = 1L;


    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String text = "some text";
        System.out.println(String.format("Lat: %s Long: %s", request.getParameter("lat"), request.getParameter("lng")));
    }

}

I suggest you to follow naming conventions:

Class names should be nouns, in mixed case with the first letter of each internal word capitalized. Try to keep your class names simple and descriptive. Use whole words-avoid acronyms and abbreviations (unless the abbreviation is much more widely used than the long form, such as URL or HTML).
