Hi, Guys:

I am completely new to Flex, and I started using the HTTPService to extract
information using the trial version until I started using the non-trial version
one. When I run the program, it now gives me this:

[RPC Fault faultString="Security error accessing url"
faultCode="Channel.Security.Error" faultDetail="Destination: DefaultHTTP"]
at
mx.rpc::AbstractInvoker/http://www.adobe.com/2006/ flex/mx/internal::faultHandler
()[E:\dev\3.0.x\frameworks\projects\rpc\src\mx\rpc\Ab stractInvoker.as:216]

ts\rpc\src\mx\messaging\channels\DirectHTTPChannel .as:368]
at flash.events::EventDispatcher/dispatchEventFunctio n()

at flash.net::URLLoader/redirectEvent()

I have installed my Flex on my C drive, and therefore I am a little confused
with the message here.
Does anyone know how I can fix this?

If you run the app from under Flex builder, you shouldn't get this error. Are
you? Or are you running it from a web server?

If from a web server, (and sooner or later you will be) then you nee a
crossdomain.xml file on the server serving the data:
http://www.test.com/crossdomain.xml

See the docs, the archive and google for details on the crossdomain.xml file.

Hi,

Thanks for replying. Yes, I am not running this on the web server, and it
turns out that the RPC appeared because I was importing extra controls that I
don't need.

I will definitely check out this article.
Thanks for the tip.
