node.js source works properly.

var util = require("util"),

my_http = require("http");

my_http.createServer(function(request,response){

  console.log("connected")

  response.writeHeader(200, {"Content-Type": "text/plain"});

  response.write("Hello World");

  response.end();

}).listen(3000);

console.log("Server Running on 3000");
