How to get text response from jquery get method?

Question

I am requesting a servlet to get a String value , for that I am doing like this.

function histryTraceFun(){
    $.get('SendNodeHistoryTracing?node='+temp,function(response){
        alert("in response "+response); // Here I am not getting response
        });
}

in servlet doGet() method I have,

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

    response.setContentType("text/html");
    String node=request.getParameter("node");


}

The controll will come to servlet but not returning to JSP , in callback function alert the value of variable response is not comming. And actually I didnot understand how response.setContentType() work. can any one help me in this please. Thank you.

Try this to send control back to your page :

RequestDispatcher dispatcher = request.getRequestDispatcher("/yourPage.html");
dispatcher.forward(request, response);

You can also add data in response :

response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("your_response");

RequestDispatcher dispatcher = request.getRequestDispatcher("/yourPage.html");
dispatcher.forward(request, response);

Still problem then post me.

Look Here, more understandable & explained code by balusc.

K . . It solved my problem. I have small doubt. I am sending request to this servlet from jquery `get()` method. can we get the value of `node` in other jsp's javascript function? – Raghu Sep 08 '14 at 06:01
