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
Well, what what web server are you running? You could probably find the procedure for setting the allowed MIME types through an online search. I'm not saying that is definitely the issue here, so maybe you can show some code?
