RE: [flexcoders] FDS / CF Endpoints
Ah yes, Joao is on the right track - I forgot that CF7.0.2 uses an RMI bridge to connect the two. I was thinking of the configuration from a CF8 + LCDS 2.5 integrated installation that is in Beta 2 right now that makes this much simpler (and avoids the need for configuring RMI to get this to work). http://labs.adobe.com/wiki/index.php/Scorpio Pete From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of João Fernandes Sent: Thursday, April 19, 2007 2:40 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] FDS / CF Endpoints Darren, when you request a fill, it will contact with rtmp or polling FDS server.

RE: [flexcoders] FDS / CF Endpoints
Is there really a servlet mapping in your ColdFusion web application's /WEB-INF/web.xml file on your srv2.mydomain.com site that is /messagebroker/*? I think ColdFusion uses /flex2gateway/* instead of /messagebroker/* for their message broker servlet mapping.

I was just following Tom's article, which specifies you add the following to
your FDS services-config.xml

Tom appears to be running both FDS and CF on the same physical server, so he's
left {server.name} in the endpoint. I need to know whether that changes - as
well as {server.port} - when you're running CF on a different server than your
FDS server.
Also, he's specified /{context.root}/messagebroker/cfamfpolling as the AMF
endpoint path, and that apparently works in his example app. If this needs to
change I have no idea what to change it too. There's no mention in his article
(or anywhere else I can find) of how to modify these endpoints for any other
server configuration when running FDS and CF on separate boxes.

Re: [flexcoders] FDS / CF Endpoints
Darren,
If you are just using FDS with CF and they run in different servers
you'll have to define a hostname property to tell FDS where to find CF
(I think, it's in the resource config folder, check the
data-management-config.xml to check the exact property). This property
must be defined in each destination you'll create.
Also the messaging gateway have something similar that is the allowedIP
addresses (CF servers) to connect and send messages to that destination.
So if you serve your FDS app from the FDS server, just let {server.name}
where it was since it will resolve at runtime to server1.yourdomain.com
and connect to FDS...
In this case, CF doesn't have to be visible to the client since it's FDS
who calls CF and not the client.

RE: [flexcoders] FDS / CF Endpoints

Not sure what other details you need, I thought I covered pretty much
everything. Anything else that's missing is basically the information I'm
looking for :-)
My Flex client is served up from SRV1 (the FDS server). It contains the
following...
---
mx:DataService id=TransferCenterDS destination=cftransfer /
---
That destination is defined in the FDS services-config.xml...
---
services service id=data-service class=flex.data.DataService
messageTypes=flex.data.messages.DataMessage adapters
adapter-definition id=coldfusion-dao
class=coldfusion.flex.CFDataServicesAdapter/ /adapters destination

/channels properties
componentapplications.flex.transfer-center.cf.TransferAssembler/component
scoperequest/scope metadataidentity
property=TransferId/ /metadata /properties /destination
/service/services
---
These two CF specific channels are also defined in the FDS services-config.xml
like this (but here's where I'm having endpoint woes)...
---
channel-definition id=cf-dataservice-rtmp
class=mx.messaging.channels.RTMPChannelendpoint
uri=rtmp://srv2.mydomain.com:2048
class=flex.messaging.endpoints.RTMPEndpoint/properties

/serialization polling-enabledtrue/polling-enabled
polling-interval-seconds8/polling-interval-seconds/properties
/channel-definition---
My Flex client also contains an ArrayCollection...
---
mx:ArrayCollection id=TransferCenterAC /
---
There is also a datagrid that has a dataprovider bound to this ArrayCollection.
---
mx:DataGrid id=junkDG width=98% height=50%
dataProvider={TransferCenterAC} mx:columns
mx:DataGridColumn headerText=ID dataField=TransferId/
mx:DataGridColumn headerText=Transfer Agency
dataField=TransferInfo_AgencyCB/
. /mx:columns/mx:DataGrid---
I also have a test button...
---
mx:Button label=Fill
click=TransferCenterDS.fill(TransferCenterAC);/---
I don't know what other information I could give you. There's not much to it.
Problem is that no matter what I use for endpoints I always seem to get one
type of communication error message or another. There's too many combinations
of endpoints and errors to list here. All I'm really looking for is an article
or blog that talks about endpoints and channels and possibly describes how they
can be configured in a distributed architecture such as mine. It's surprising
it's not already out there as Flex, FDS, and CF are all supposed to work
together so nicely. You'd think there'd be more information on how to set the
three up in a distributed way. You can find tons of tutorials on FDS using
java assembler, dao, and object classes, but almost nothing on using CFCs on a
CF server running on a separate physical server.

João, yes, from what I understand that's what the...

id=cf-polling-amf class=mx.messaging.channels.AMFChannelendpoint
uri=http://{server.name}:{server.port}/{context.root}/messagebroker/cfamfpolling;
class=flex.messaging.endpoints.AMFEndpoint/
sections are for in the services-config.xml Channels definition. Tom says to
add them to the services-config.xml because all the standard FDS channel
definitions are already in there... but you need to add the CF channels so FDS
can talk to the CF server. I've done that, my problem is that I can't seem to
get the CF endpoints right. What is /messagebroker/cfamfpolling and how do I
know what port it's running on? There's nothing in Tom's article syaing you
need to go into CFIDE and turn anything on, so...?
Also the messaging gateway have something similar that is the allowedIP
addresses (CF servers) to connect and send messages to that destination.
Not sure if you mean the crossdomain file... I have that. If you mean
something else then maybe you could be more specific? In the CFIDE there are
checkboxes to let FDS talk to CF... those are checked. There's also an IP
listed in the allow box so CF will allow the FDS server in, so... are you
talking about something else?
So if you serve your FDS app from the FDS server, just let {server.name}
where it was since it will resolve at runtime to server1.yourdomain.com and
connect to FDS...
Yes, that's fine for the standard FDS channel definitions... but you need
correct endpoints for the CF channels.
The EndPoint must target always FDS and never CF.
Yes, the FDS endpoints target FDS... but the CF endpoints must be set correctly
for FDS to find CF... that's where I'm having a problem. It's supposed to be
cut n paste when the CF server is on the same box as the FDS server, but when
it's not... then what?
Thanks!
Darren
Re: [flexcoders] FDS / CF Endpoints
No Darren, CF type endpoints MUST point to FDS and NOT to CF itself. It's always FDS that will communicate with CF and never the swf file itself. I'm not talking about the crossdomain but the data-management. In there you have all your destinations definitions. If you take a look in the deployment of FDS (c:\fds?) there is a resource\config folder where you can find an example of a cf destination. inside of it, you'll see that there is a property that will define which host is using cf and that destination will try to connect. in the admin panel that you talked about, yes, you need to configure FDS IP address there so CF will allow that machine to communicate with CF itself. The main point is, if you don't define in your destination configuration (destination id=somedestination...) what is the cf hostname, FDS will think that CF is running locally. João Fernandes
