[Fiware-tech-help] [WebUI][3DXML3D Issues] XML3D doesn’t load json resources

[Philipp Slusallek]

Hi,

This is an expected behaviour of XML3D because of the CORS (Cross-Origin
Ressource Sharing) handling in browsers. The browser refuses to access
other local files referenced from a local HTML page because of security
reasons.

This can only be dealt with by going through a Web browser, where the
browser adds the necessary HTML CORS-headers (which impossible with
local files).

Just to clear: The installation manual never suggests to locally copy
and run the examples. And this behaviour is documented for XML3D.

But we will check again and may make sure this more prominently visible
in the installation manual to avoid similar user errors in the future.

BTW, this still is ticket HELP-1003 right now.

Best,

	Philipp
