Question

I am having problems using Gzip compression and JQuery together. It seems that it may be caused by the way I am sending JSON responses in my Struts Actions. I use the next code to send my JSON objects back.

public ActionForward get(ActionMapping mapping,     ActionForm     form,     HttpServletRequest request,     HttpServletResponse response) {        JSONObject json = // Do some logic here        RequestUtils.populateWithJSON(response, json);        return null;              }  public static void populateWithJSON(HttpServletResponse response,JSONObject json) {     if(json!=null) {         response.setContentType('text/x-json;charset=UTF-8');                    response.setHeader('Cache-Control', 'no-cache');         try {              response.getWriter().write(json.toString());         } catch (IOException e) {             throw new ApplicationException('IOException in populateWithJSON', e);         }                                    }  } 

Is there a better way of sending JSON in a Java web application?

Answer 1

Instead of

try {        response.getWriter().write(json.toString()); } catch (IOException e) {        throw new ApplicationException('IOException in populateWithJSON', e); }         

try this

try {         json.write(response.getWriter()); } catch (IOException e) {         throw new ApplicationException('IOException in populateWithJSON', e); }                                       

because this will avoid creating a string and the JSONObject will directly write the bytes to the Writer object
