How to load custom places from file or db

[AndTom]

Hello since Google maps can load custom places from .xml file, what about Arcgis, I found that they have example, but its saved in .json format, while i retrieved their example .json and put on my local server seems it can't load, so how to load custom places using Arcgis? Example: https://developers.arcgis.com/javascript/3/sandbox/sandbox.html?sample=fl_featureCollection

I read that server must be enabled mime types, so I enabled these:

application/vnd.geo+json

application/geo+json

My server is XAMPP:

XAMPP Installers and Downloads for Apache Friends 

Do I need todo more, because it doesn't load

My first file saved as json:

function requestphoto

function requestPhotos() {
//get geotagged photos from flickr
//tags=flower&tagmode=all
var requestHandle = esriRequest({
//url: "https://api.flickr.com/services/feeds/geo?&format=json",
//url: "objects.xml",

url: "objects.json",
callbackParamName: "jsoncallback"
});
requestHandle.then(requestSucceeded, requestFailed);
}

And it throws in cosole always failed, files are in same directory, what I'm missing?
