How to set JSON data in node.js response object? - node.js

Question

I am using html on client side and my server side code is on node.js. I have some url's defined in to the nodejs application and I am calling them from my client html file. From node I am calling my REST application which is at another server. This rest application is written in Jersey java web services. I am able to call node.js from my html and from node code I am getting response from Jersey web service module. After receiving this response I am setting it to response object of node.js but this response is not available on html jquery ajax call.
$.ajax({
type :"POST",
dataType: 'json',
data: jsontest,
url: 'http://<code>localhost</code>:9999/hello',
success: function(data) {
console.log('success');
console.log(data);
console.log(data.id);
}, error : function(response) {
console.log(JSON.stringify(response));
}
});
Server side code:
var tmp = req;
var authentication = JSON.stringify(tmp.body.authenticationKey);
console.log("authentication :- "+authentication);
requestObj({
url : "http://<code>restserver</code>:port/restmodule/controller/hello",
method : "POST",
headers : { "Content-Type" : "application/json","pubKey":authentication},
body : JSON.stringify(tmp.body)
},
function (error, res, body) {
indexresponseBody = JSON.stringify(JSON.parse(body).message);
}
);
res.writeHead(200, {'content-type':'text/html'});
console.log("JSON returned from REST "+indexresponseBody);
res.write(indexresponseBody);
res.end();
I am able to get the json and this is printed on node server console. But when I am writing this json to the response(res) object on firebug console I am not able to see this json. Can anybody tell me how can I get this response.

Could be because of async nature of callback, try this -
function (error, resp, body) {
indexresponseBody = JSON.stringify(JSON.parse(body).message);
res.writeHead(200, {'content-type':'text/html'});
console.log("JSON returned from REST "+indexresponseBody);
res.write(indexresponseBody);
res.end();
}
