Jamie,
The RemoteObject (client side) found in my example is the same code
used for Cairngorm or non-Cairngorm applications.
Flex 2.0 and AMF3 (not sure where the requirement comes from, probably
AMF3) requires that you have a destination defined.
For Java adapters you can not use the "source" attribute and must
explicitly set it in the configuration file. By default FDS is setup
to have the main config file be services-config.xml which includes
other files, here is an example.
<services>
<service-include file-path="remoting-config.xml" />
<service-include file-path="proxy-config.xml" />
<service-include file-path="messaging-config.xml" />
<service-include file-path="data-management-config.xml" />
</services>
The default ColdFusion Adapter which is setup by ColdFusion MX 7.0.2
defines a destination named ColdFusion and with a source="*" which
allows the developer to set the source attribute on the RemoteObject.
The defualt endpoint is also setup to:
<channels>
<channel-definition id="my-cfamf"
class="mx.messaging.channels.AMFChannel">
<endpoint
uri="http://{server.name}:{server.port}/flex2gateway/";
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<polling-enabled>false</polling-enabled>
<serialization>
<instantiate-types>false</instantiate-types>
</serialization>
</properties>
</channel-definition>
</channels>
For other technologies supporting AMF3 it depends on how they are
implemented. But since they are custom adapters they are pretty much
open and do not have any restrictions and following ColdFusion's
config setup works for SabreAMF, WebORB for PHP, and AMFPHP 1.9.
You can find examples of all three on my blog. But the particular
AMFPHP 1.9 example shows that the config file doesn't even need to be
called services-config.xml. I setup the Flex project and point the
-services compiler argument to amfphp19-services-config.xml file. In
side this file I setup a basic destination and the most import part
setup the endpoint.
<?xml version="1.0" encoding="UTF-8"?>
<services-config>
<services>
<service id="sabreamf-flashremoting-service"
class="flex.messaging.services.RemotingService"
messageTypes="flex.messaging.messages.RemotingMessage">
<destination id="AMFPHP1_9">
<channels>
<channel ref="my-amfphp19"/>
</channels>
<properties>
<source>*</source>
</properties>
</destination>
</service>
</services>
<channels>
<channel-definition id="my-amfphp19"
class="mx.messaging.channels.AMFChannel">
<endpoint
uri="http://{server.name}:{server.port}/amfphp1_9/gateway.php";
class="flex.messaging.endpoints.AMFEndpoint"/>
</channel-definition>
</channels>
</services-config>
Now you have to have the destination but the endpoint is optional. So
you with the above configuration file link into the compiler through
-services argument you can have RemoteObject code like:
<mx:RemoteObject
id="roTestService"
destination="AMFPHP1_9"
source="MyTestService"
result="Alert.show( event.result + '', 'Result' )"
fault="Alert.show( event.fault.faultString , 'Error' )">
<mx:method name="testMethod" />
</mx:RemoteObject>
Note: for FDS default setup you will want to add the services
destination and channel configuration code to the remoting-config.xml.
I just updated my CairngormStore Multiple Backend example and have put
it live on my blog. You can find the live running example at:
http://api.renaun.com/flex2/posts/CairngormStoreMultipleBackend/
It demonstrates how to connect to different backends, ColdFusion,
AMFPHP (AMF0 using my RemoteObjectAMF0), AMFPHP 1.9 (AMF3), and
WebServices. You can get the source at:
http://api.renaun.com/flex2/posts/CairngormStoreMultipleBackend/CairngormStoreMultipleBackend.zip
Hope that helps,
Renaun
PS: I just noticed your other post I'll post directly to you code in bit.
