I have been using option 2 for quite some time now

Is there a standard services-config.xml file that already has a ColdFusion destination set up that people can download? I'm having a lot of trouble getting Flex to talk to ColdFusion.

Faisal, good to know, thanks.

Andrew, yep, it is in the flex folder under ColdFusion's WEB-INF folder.

Ben,

I emailed you earlier about the Flex servies-onfig.xml file and how to configure it to use with CF. Here's my services-config.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<services-config>

<services>

</services>

When I try to use this, I get the following error in Flex Builder:

Unexpected child element 'destination' found in 'services-config' from file: services-config.xml.

Have you ever seen this before?

# Posted By Andrew | 1/18/08 8:29 PM

If you are having any problems, you can and may need to, depending on your configuration, change:

{server.name}:{server.port}{context.root}

to the exact path. Or try leaving off {context.root} if needed.

# Posted By Clint | 1/19/08 12:36 AM

Clint / Ben,

Earlier this morning I changed the {server.name}:{port}{contextroot} to the exact path for my CF server and now I can access my data.

# Posted By Andrew | 1/19/08 6:14 PM

Is there documentation available for the services-config.xml? In Flex 2, I recall this file being simpler, and I use (based on a blog entry Ben posted, actually) local copies of this file to point specific projects at specific, remote ColdFusion servers. This is especially handy for debugging CF services that work locally, but not remotely. This is harder to set up in Flex 3, since you need (I assume) 4 other files. I've gotten this to work in Flex 3, but it would be nice to strip out all the stuff I don't need and just drop in a customized file in the local libs/ folder.

# Posted By Ken Dunnington | 1/23/08 8:57 PM

Changing this stuff

{server.name}:{server.port}{context.root}

to the exact path isn't really a good solution. What if you're deploying to multiple servers? Does anyone know where these variables come from?

# Posted By Meh | 1/24/08 3:38 PM

That's why I only change it in a project-local /libs folder :) I don't want to change the file in WEB-INF, I always compile against that file when I'm building for production, but if I'm compiling and running/debugging a Flex app locally, but want to connect a RemoteObject to a remote server, modifying the channel definition seems like the best way. If there's a better solution, though, I'd love to hear about it.

# Posted By Ken Dunnington | 1/25/08 1:27 PM

I am experiencing issues connecting to ColdFusion, too. The additional wrinkle is that I use Apache as the Web server. When I put a CFC in the ColdFusion root folder, the location does not validate.

My Flex services-config.xml file looks like the one Andrew posted earlier in the post. Under the "Flex Server" preference, I have the following two entries (that validate properly):

Root folder: C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\cfdocs
Root URL: http://localhost/cfdocs

The start of the <mx:RemoteObject> is:

<mx:RemoteObject id="myRemoteObject" destination="ColdFusion" source="RealStore.src.remoteService" showBusyCursor="true">

I have stored the remoteService.cfc file in the C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\cfdocs\RealStore\src folder.

I get an error that says "Ensure that the name is correct and the component or interface exists."

I tried changing the path of the endpoint URI in the services-config.xml file from http://{server.name}:{server.port}{context.root}/flex2gateway/ to http://localhost/cfdocs." target="_blank">http://localhost/cfdocs. That did not help.

The error message wording leads me to believe that the correct faulthandler method is being invoked.

I am clearly missing something simple. Any thoughts/pointers?

Thanks in advance,

What if I'm running CF on a remote linux server? It doesn't look like I can configure the new project to look at the remote CF server.

# Posted By Scott | 5/12/08 9:17 PM

Scott - You can configure it to automatically redirect to the ColdFusion being run on the remote Linux server. Just read over the configuration manual once again and you'll get the hang of it.

You could even try visiting my site http://www.businessminded.co.uk and navigate to the "Guides" section to find the manual. I've highlighted the relevant section.

# Posted By Business Directory | 5/31/08 7:54 AM

Oops! Sorry for yet another comment but I mistyped my website. It's actually http://www.businessmagnet.co.uk. BusinessMinded is a site I'm just about to develop.

# Posted By Business Directory | 5/31/08 7:59 AM

Hi I m in the same problem , the url www.businessmainded.co.uk is showing error. I have found www.businessmagnet.co.uk -as suggestion from Google. DO you meant that ? where is the guide

# Posted By Learner | 5/31/08 8:01 AM

I need to set the FLEX3 compiler services arguement to the services-config file on a separate server (multiple instances of CF) on our network.
Any suggestions on how to 'map' to that file's path?

HELP PLEASE
I am trying to save a image to my coldfusion server of a chart that is displaying in my flex application.

1. coldfusion is installed using JRUN
2. IIS
3. my component is installed wwwroot/com/
4. services-config.xml are the same as the one displayed

When i run the flex application and click on the export button i always get a error.
