Question

Answer 1

A:

I have encountered the same issue which was actually because of the some issue with json or ajax call. In your json call it should be {"test":"test"} instead of {test:"test"}.

Try it should work if this is the issue.

Answer 2

A:

I've found the solution to the problem by some hit & trial. It is because when we make getJSON() call on cross domain then response should be wrapped inside a function name. This function is our callback handler for the response in the script.eg

html file :

 <html>
    <head>
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js'&gt;&lt;/script&gt;
    <script type='text/javascript'>
    $(function(){
       $.getJSON("localhost:8080/test.jsp?callback=?");
    }
   function test(data){
      alert(data.feed);
    }

And the jsp test.jsp

<%@ page language="java" contentType="text/json; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%
response.setContentType("application/x-javascript");
out.write("test({\"feed\": \"test\"})");
%>

hope if anybody has the same problemm this will help.you can pass the callback function name as a parameter and make jsp at the server such that it uses that name to wrap the response.
