RE: [flexcoders] [Flex 2] Crossdomain issue

2006-10-18 Thread Peter Farland






Hey Thomas,

I should point out that you have a few options when 
connecting to ColdFusion from a Flex 2 application (well, for any Flex 2 
application but I'll keep this reply CF focused).

The first thing I want to mention is thatfor RPC 
services like RemoteObject, and WebService and HTTPService (when using the 
proxy) you can avoid specifyinga services-config.xml file so long as you 
take on the responsibility of programmatically specifying where the channel 
endpoint(s) are for a service. I would suggest this approach if you are 
connecting to an endpoint other than FDS and you're not comfortable futzing with 
the configuration across two app servers.

1. The first way to specify a set of channels that can be 
tried to find a suitable endpoint to communicate with a destination. This 
approach is hinted in the docs...

http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=1101.html
... but to make it more explicit I'll reproduce the 
relevant ActionScript code here:

import mx.messaging.ChannelSet;
import mx.messaging.Channel;

import 
mx.messaging.channels.AMFChannel;

...var cs:ChannelSet = new ChannelSet();var 
customChannel:Channel = new AMFChannel(null, "http://localhost:8700/cfusion/flex2gateway/");cs.addChannel(customChannel);myRemoteObject.channelSet = 
cs;...

Note that we pass a null channel id to the channel 
constructor so that we don't have to know what the channel-definition is called 
in the relevant /WEB-INF/flex/services-config.xml file. The channel id is only 
to help services catch a mistaken channel assignment which is only really 
important for publish/subscribe services as if one were to assign a non-polling, 
non-real-time channel you'd never received pushed updates.

Also note this approach should work for other RPC services 
too (well, it is true for publish/subscribe services too like 
Producers/Consumers for the FDS message service and the data management 
services).


2. Another quick and dirty way to do this for the MXML API 
of RemoteObject ONLY is to use the legacy endpoint 
attribute:

mx:RemoteObject id="myRemoteObject" endpoint=http://localhost:8700/cfusion/flex2gateway/ ... /

Under the covers the MXML tag will use the endpoint to 
create a default channel set for you (it'll use AMFChannel for URLs starting 
with http, and SecureAMFChannel for URLs starting with 
https).


Pete

2006-10-17 Thread Thomas Rühl


Hi Peter, thanks for your reply.

I initially tried the configuration without the to-ports attribute, but 
no success there either. At the moment, I placed the crossdomain.xml in 
every folder I could find, that possibly could be accessed by 
FlashPlayer to gather the file.

However, it should only be placed in the root. As I wrote, in my case I 
can access the file directly using 
http://10.12.104.10:8700/crossdomain.xml, so I really do not understand 
what's going on there... It seems, as if the config loads now for some 
strange reason, but I'm getting another error on the server-side:

Requested resource '/flex2gateway/' (%2fflex2gateway%2f) not found

So... I drilled it down towards the services-config file(s)... Since I 
am using FDS alongside with RPC, the application is hosted by FDS, but I 
adapted an individual services-config-plusRemoting to enable 
FlashRemoting and the use of the Coldfusion gateway flex2gateway. Every 
change to the config, I do in both files - the adapted one that the 
compiler uses and that is included in the swf, and the original one that 
is available for FDS at runtime.

For the flex2gateway channel, they are both configured like this:
!-- Coldfusion amf channel --
channel-definition id=my-cfamf class=mx.messaging.channels.AMFChannel
endpoint 
uri=http://{server.name}:{server.port}{context.root}/flex2gateway/; 
class=flex.messaging.endpoints.AMFEndpoint/
  properties
   polling-enabledfalse/polling-enabled
serialization
 instantiate-typesfalse/instantiate-types
/serialization
  /properties
/channel-definition


What am I doing wrong here??

Cheers, Thomas.

This shouldn't matter, but can you try removing the 
to-ports attribute in the crossdomain.xml but leave the domain attribute in the 
allow-access-from element?

Are you using mxmlc to compile the SWF and if so, is there 
any chance that you changed the network access policy when compiling the SWF 
(i.e. set -useNetwork to false if compiled with 
mxmlc)?
