Making Flash Remoting easier in Flash CS3
by Thibault Imbert
Here is something I have just added into my
in the Flash Remoting chapter and wanted to share with you
As you may know, no wra er cla is embedded into Flash CS3 for your remoting calls, you have to use the raw
cla which is not very practical in a large project.
I wanted a simple cla to call some remote methods in Flash CS3 like the
cla does in Flex, and like the Service cla we had in Flash 8. I came acro which is very smooth, but noticed that it was not working the way I wanted it.
So I created a wra er around the NetCo ection object which behaves like the Service cla we used to have with a PendingCall a igned to each remote procedure.
Here is how you create the remote service :
// create a remote object (Singleton)
var service:Service = Service.getI tance();
// set the required infos
service.setRemoteInfos (http://www.bytearray.org/wp-content/projects/remotingservice/amfphp/gateway.ph am quot;,
org.bytearray.HelloWorld,
ObjectEncoding.AMF3 );
Then you call the remote method, this retur you a PendingCall object :
// call the remote method
var rpc:PendingCall = service.sayHello(Hello there ?);
The PendingCall object is di atching two events, ResultEvent.RESULT and FaultEvent.FAULT :
// call the remote method
var rpc:PendingCall = service.sayHello(Hello there ?);
// wait for the result event (everything is ok)
rpc.addEventListener ( ResultEvent.RESULT, succe );
// wait for the fault event (an error occured)
rpc.addEventListener ( FaultEvent.FAULT, error );
// get the result
function succe ( pEvt:ResultEvent ):void
// output : you said : Hello there ?
trace( pEvt.result )
// get the result
function error ( pEvt:FaultEvent ):void
trace( pEvt.fault.description )
You can change the service or gateway at any time :
service.service = org.bytearray.AnotherService&am quot service.gatewayURL = http://www.myserver.org/amfphp/myOtherGateway.ph am quot Or authenticate yourself with some credentials :
service.setRemoteCredentials (, groove);
Sources and file examples available
Update (05/04/09) : Version 0.2 : Changed the Service implementation as a Singleton.

fu y i thought the same about the as3 lightweight remoting framework (mi ing listeners on calls) and just as i started to write my own implementation i found the SSR (super simple remoting
). it works as expected and saved some time. but thanks for your implementation none the le *gg*

Hi Mike,
yes such a feature can be added, I will add that
Hi William,
The book is called “Pratique d’ActionScript 3″ and is written in French. O’Reilly should tra late it after the release !

Why not just import the rpc.swc from the Flex SDK, why reinvent the wheel here…

Hi Thibault,
thanks for sharing your solution with us. May I ask, under which licence you’re publishing the code? Am I allowed to use it in commercial projects and am I allowed to modify it to my ecial needs?

There is no licence. You can modify the code and do whatever you want with it

Questio #8230;how can I make Flash remoting - ColdFusion secure?
It seems that you have to set a CFC to acce =”remote” but that allows anyone in the world to run it as well.

Waiting for your book to see it in English
Here is what i wanted to admit: In some way, FaultEvent is not di atched, or catched by event listener, in Flex 3.

I’m having problems getting this to work with query retur from ColdFusion.
var results:Object = pEvt.result;
var queryItems = results.item for (var queryIndex=0; queryIndexqueryItems.length; queryIndex++)
This i et wo #8217;t work since the items object is undefined. Anyone know how this should be done in AS3?

Figured it out. This code i et can be used to find the old style Recordset
Retur an array with objects, that works the same way as the results.items did in AS2.
Return events from AS3 Flash Remoting calls only contain one member when returning,
and it’ called “ erverInfo”. Pa that object to this method, and the normal array is then returned.
Stupid that Adobe has not implemented this themselve #8230;
Example:
function listEvents_Result( pEvt: ResultEvent ):void
var results = pEvt.result;
results["items"] = RemotingUtil.getRecordSet(results.serverInfo);
for (var queryIndex=0; queryIndexresults.items.length; queryIndex++)
var queryObj = results.items[queryIndex];
trace(queryObj.name);
trace(queryObj.date);
In this example we a ume that the recordset has the two colum “ ame” and “date”.
public static function getRecordSet(serverInfo:Object):Array
var queryItems = serverInfo.initialData;
var queryColum = serverInfo.columnName var retArray:Array = new Array();
for (var queryIndex=0; queryIndexqueryItems.length; queryIndex++)
var queryObj = new Object();
for (var j=0; jqueryColum .length; j++)
queryObj[queryColum [j]] = queryItems[queryIndex][j];
retArray.push(queryObj);
return retArray;

Hi SiggeLund,
Yes, in Flash CS3 when you are receiving a query from the server you receive an objet with a serverInfo property that you have to parse the co truct an a ropriate RecordSet.
Adobe decided to remove the Flash Remoting components from Flash CS3 which is in my opinion a real mistake. Flash CS4 should solve that limitation

Hi SiggeLund,
I ca ot talk about it for the moment
, but as soon as po ible I will post a tutorial here about the new capabilities offered by Flash CS4 in terms of Remoting.
Yes ServiceCapture is a must-have when it comes to Remoting debugging.

Hi Thibault, we also implemented a remoting package in our as3 ope ource project (we are a commercial company) recently launched at
It also features built in su ort for recordsets which is a datatype i tead of a multidime ional array as presented in the example above.
It also tackles the problem you tackled with da y patterso #8217 implementation, which is that you can only call one method on one service. Both your and our solution fixed that by providing handlers/events for each method called on the service

Thanks for the post`-`
I have been going crazy trying to use flash remoting in CS3 with a cfc backend, and with no luck.
I am at school now, but I am going to try this when I get home.
