Calling servlet to load the data using jquery ajax?

Question

I am new to JQuery. I have a servlet which will fetch data from the database and the result is kept is request and the same result is retrieved in jsp file. Now i have to call the servlet using ajax jquery to load the data. I am doing as below. But it is not loading. Please help me.

$('#myForm #revert').click(function() {

        $.ajax({
            type: "GET",
            url: "./myController",
            success: function(msg) {
                <span style="color:green;font-weight:bold">Successful</span>');
            },
            error: function(ob,errStr) {
                //Todo

            }
        });

        });

Servlet code:

//Service call gets data and the result is kept in request scope as below
request.setAttribute("myresult", result);
request.getRequestDispatcher("/WEB-INF/myScreen.jsp").forward(request, response);

Thanks!

I doubt this is valid JS - have you checked in your browsers error console? — Gyro Gearless

Ajax is not a normal HTTPRequest,You canot Forward or sendRedirect a Ajax request

Since it is Asynchronous,you need to write the response for Ajax request

PrintWriter out = resp.getWriter();
out.println(resultString);
return;
