You are unable to connect Adobe Flex Builder 2 RemoteObjects to Adobe ColdFusion 8 CFCs.


Flex Builder 2 projects containing RemoteObject calls to ColdFusion 8 fail to connect for the following reasons:

  • You have not entered the proper compiler arguments which point to your ColdFusion 8's services-config.xml and or your ColdFusion server's context root.
  • You have created your Flex Builder 2 project as a "ColdFusion Flash Remoting Service." This is not appropriate if you are connecting to ColdFusion 8 CFCs.
  • You are using ColdFusion 8's embedded web server (typically running from port 8500) and you are trying to run your Flex project from within Flex Builder.
  • You do not have your ColdFusion 8 CFCs located in your server's web root.


Create your Flex Builder 2 project

  1. Create a "Basic" (e.g. XML or web service from PHP/JSP/ASP.NET) Flex project.
  2. Change your project's Output folder to point to your web root (if using ColdFusion 8's embedded web server, use {cfusion8_root}/wwwroot/your_project_name).
  3. Click Finish, right-click your project from the Navigator pane of Flex Builder 2, and then choose Properties.
  4. In the Flex Compiler section, add the appropriate Additional Compiler Arguments. For example:

    -services=C:\ColdFusion8\wwwroot\WEB-INF\flex\services-config.xml -context-root=/ -locale en_US.

  5. Click OK

Ensure ColdFusion 8 CFCs are setup properly

  • If using ColdFusion 8's embedded web server, ensure you have you CFCs located somewhere beneath the {cfusion8_root}/wwwroot/ directory
  • If using an external web server, ensure you have your CFCs located somewhere beneath your web server's web root, for example IIS is typically C:/Inetpub/wwwroot/
  • Ensure the "source" attribute of your Flex Project's <mx:RemoteObject> is correct. If your CFC is located in /wwwroot/myCFC/someCFC.cfc, then your "source" entry would be "myCFC.someCFC".
  • Ensure your database serving the data to your CFC is started and the ColdFusion 8 DSN is configured properly within ColdFusion Administrator

Run your Flex Application from the web root

  • Compile your project, but instead of running it from Flex Builder 2, open a web browser and go to http://host_name/website_name/flex_app_name/flex_project_name.html.
