Not able to connect web service API from Flash application

Hi,

i have developed a flash application (SWF) and uploaded to one meeting in adobe connect. Users could able to access the flash application. My Flash applications supposed to know the user details who currently logged in. For that i tried to get the user info from my flash file using Web servicee API. But i am getting the below error.

Request for resource at http://xxxx.adobeconnect.com/api/xml?action=common-info by requestor from file:///C|/Users/xxxxxxxx/Documents/flash%20projects/service1.swf is denied due to lack of policy file permissions.

I have done a bit research and hoping that problem with cross domain file. Can you please help me what might be the problem? and how i can update cross domain file?

NOTE : when i try the same api call in browser and also from .net programs i could get the results. When i send request from flash file then only getting error. At the same time i could get the data from my own web service using the same flash file.

Thanks..
