I'm working on a jsFiddle with a OpenLayers example in it. http://dev.openlayers.org/releases/OpenLayers-2.11/examples/snapping.html
At the moment it's not working because it's not getting a response for the http request to get data. How do I fix that?
The jsFiddle is here: http://jsfiddle.net/TcuxA/6/ Go to the line "// create three vector layers" in the script. There are three requests for data. If you type the URLs in your browser you get the JSON, but my Firebug gives 3 errors when I run the jsFiddle.
I tried fixing with jsFiddle echo, but that didn't work. I don't know how to change the script to load the data otherwise.
Why can't I get the JSON by these URLs? What are good solutions?
