Answer 1

Solution: for Flex 4.x (Currently 4.6) and AS3 in Flash Builder:

    import flash.system.SecurityDomain;
    import flash.system.ApplicationDomain;
    import flash.system.LoaderContext;
    var loaderContext:LoaderContext = new LoaderContext();
    loaderContext.applicationDomain = ApplicationDomain.currentDomain;
    loaderContext.securityDomain = SecurityDomain.currentDomain; // Sets the security 

context to resolve Error # 2121

... now load your SWF with

loader.load(new URLRequest(webServerWebURL),loaderContext);

Answer 2

Add your working folder in the Global Security Settings panel. This allows you to load external files from a single SWF in your file system. Its the same if you want a.swf to load b.swf even if they is located in the same folder.

• Go to the Settings panel: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html
• Choose "Add Location" from the dropdown
• Click "Browse for folder" and add the folder containing your SWF

This will allow your SWF to read external files.

This should not be a problem if you upload you SWF to a server though.

Your error is from the external location not having a cross domain file, not you. Check out this tutorial on using a bridge file to communicate with an external api. I used as3 and php in this example. The trick is to maintain control of the cross domain file on your domain.Then let your server communicate with the api.
