Actionscript export problem

I have an actionscript file that I am trying to export from Adobe Flash Builder 4. The program reads in a json.txt file. It works fine when I run it and view it in a browser. I then right-click on the .as file, and choose 'export' -> 'release build' and save it on my computer.

Then, when I open up the .html fil开发者_如何转开发e, it can no longer load the json file. I have this json file stored online, in a publicly accessible place (a http:// site), and can reach it from my browser.

Are there any particular things I need to look out for when doing this? For example the web address is

"http://web.asdf.edu/rdw/Public/data/dq3.json.txt"

Is it possible that this is too long?

Can't access the server from here, but it's quite possible you can't load it because it doesn't have a cross-domain policy file (like Flickr does, for example). Server contents are not accessible then.

If that's the case, you'd be still able to test because the standalone player will load the data on local tests, but then it won't work in a browser.
