How to resolve CORS ie same origin policy in angularjs

I am developing a mobile application in angularjs where I have to make call to web service. But, when I am making the call with $http.get it is giving the following error.

XMLHttpRequest cannot load http://example.com/First_Step.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8020' is therefore not allowed access.

My function for this is as follows:

$scope.firstStepClick = function() {
    appSvc.selectedItem = "firstStep";
    $rootScope.go('parent/firststep', 'slideLeft');
    delete $http.defaults.headers.common['X-Requested-With'];            
    $http.get("http://example.com/First_Step.json").success(function(data) {
        $scope.firstStepData = data;
    }).error(function() {
        alert("an unexpected error occured");
    });
};

So, please help me to solve this CORS problem. I am using html5, css3 and angularjs for this mobile app development.

Thanks in advance

apache:

http://enable-cors.org/server_apache.html

nodejs

res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "Content-Type");

apache sling

http://sling.apache.org/apidocs/sling5/org/apache/sling/api/servlets/SlingSafeMethodsServlet.html#doOptions(org.apache.sling.api.SlingHttpServletRequest,org.apache.sling.api.SlingHttpServletResponse) utilise doOptions and return Allow

unfortunatelly I'm not an apache sling expert and that's how much i was able to google, check your network tab, the first call to your server is a 'OPTIONS' call which returns what options are allowed it should return * or specific ones like 'get' or 'post' depending on needs then the reall call will be made

You don't have to do anything in the Angular side.

The server side is the one responsible to send the rights headers to enable CORS

Take a look a this:
