Recently I found this magic class in the Flex 3 SDK called ServerConfig. This class is great… What it allows you to do is access values that you defined in your services-config.xml file used to define the communication channels between Flex and your server.

Take the following services-config.xml file for example:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21

<?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>*</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>

As you can see, we’re setting the endpoint for our my-amfphp channel to gateway.php. What if you wanted to read that value into your Flex application? You could use the following code:

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