Flash Remoting not working from browser

Question

Quick Problem:
I have a movie that connects and displays the data fine when
run by testing
the movie from within flash its fine however as soon as i try
to run it from
the html or by IIS link to the swf, or even by browsing to
the swf via file
manager it fails to connect.
Any ideas why?
Thanks,
Koop.
Full Description:
My code was connecting fine before or at least i think it
was.
Does anyone have a basic fla that works for them using the
methods below
that i could test on my machine?
the connection code is as follows:
code =============
import mx.remoting.*;
function Result()
//receives data returned from the method
this.onResult = function(result)
trace("Data received from server : " + result +
result.items.length + "
items were received" );
//this is where we put the data in the text field
for (i=0;i<results.items.length;i++){
dataField.text = dataField.text + result.items.length;
dataField.text = dataField.text + result.items.length;
this.onStatus = function(error)
trace("Error : " + error.description);
dataField.text = "Error : " + error.description;
NetServices.setDefaultGatewayUrl("<mygatewayurl>");
var gw = NetServices.createGatewayConnection();
var server =
gw.getService("flashservices.gateway.interaction", new
Result());
server.getLatestNews();
end code ================
A few things have flagged in my mind, they may be way off
track however;
- Recent security changes in browsers (click here to
activate...)
- My wildcard import on the first line however i'm not sure
which
dependancies i specifically need to compile this project.
- cross domain security restrictions.. i am currently
connecting to a
service at a remote server from my local machine/IIS
what confuses me is that good ol' CTRL+ENTER works fine but
obviously fails
on any parameter calls such as loading
"newsitem.swf?theID=<variableID>"
which requires that it be run via a webserver.
Any help would be appreciated.

Answer 1

I had a similar prob and found it was caused by recent
security changes
to the flash player.
I was using "127.0.0.1" as the address to my gateway but it
was being
ignored because it didnt match as being the same host which
was being
evaluated as "localhost". So I found that changing the
gateway address
to "localhost" fixed it!
Solution: on your server (local or remote), put a file
"crossdomain.xml"
in the webserver's root and fiddle with its contents so it
contains all
the possible varieties of the domains you want to allow
access from.
e.g.
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy
SYSTEM "
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="
http://www.yourdomain.co.uk"
/>
<allow-access-from domain="www.yourdomain.co.uk" />
<allow-access-from domain="yourdomain.co.uk" />
</cross-domain-policy>
That (I think) will solve your problem.
