How to return JSON response back from JSP to an $.get() call?

Question

In PHP, we return the JSON to an AJAX call like this:

json_encode($data);

How do we do that in JSP?

JSP:

<%      
    gson.toJson(map, System.out);  // last line
%>

jQuery:

$.get("lookup_all_phone_numbers.jsp")
    .done(function(data){
        $("#results").append(data);
    });

I wouldn't bother with a JSP file but instead have your controller send the JSON directly to the client. What framework are you using (SPring, Struts, etc)? — nickdos, Jan 15 '14 at 05:21
Just write the JSON out via the HttpServletResponse object. You'll need to use a library to convert the Map to JSON first (see http://stackoverflow.com/q/13340138/249327). — nickdos, Jan 15 '14 at 05:47
You do not need to use JSP to return JSON format. I see, lot of people uses JSP for html representation. If you want JSON, then you can return directly from code instead of JSP rendering. — Fizer Khan, Jan 15 '14 at 06:59

I ended up using:

out.print(gson.toJson(map));
