Ecco come accedere al file services-config.xml in runtime.

<?xml version="1.0" encoding="UTF-8"?>
<services-config>
	<services>
		<service id="amfphp-flashremoting-service" class="flex.messaging.services.RemotingService"
				messageTypes="flex.messaging.messages.RemotingMessage">
			<destination id="amfphp">
				<channels>
					<channel ref="my-amfphp"/>
				</channels>
				<properties>
					<source>*
				</properties>
			</destination>
		</service>
	</services>
	<channels>
		<channel-definition id="my-amfphp" class="mx.messaging.channels.AMFChannel">
			<endpoint uri="gateway.php" class="flex.messaging.endpoints.AMFEndpoint"/>
		</channel-definition>
	</channels>
</services-config>

Provare:

trace(ServerConfig.getChannel("my-amfphp").endpoint);
