[flexcoders] Help with remote objects..

Wed, 31 May 2006 23:25:04 -0700

I have a bit of time before I start working on a new project and I would like to learn how to use remote objects. I have written a really simple app that uses remote objects to call information from my cfc and display it. However everything I have tried ends up with the same error.

Bit of information, I am using the coldfusion connectivity extention for f2b, I am running the newest version of cf.

I have my local cf server running at.
C:\CFusionMX7\wwwroot

My compiled swf is in
C:\CFusionMX7\wwwroot\test

My CFC is in
C:\CFusionMX7\wwwroot\test\com

Here is my code.

ERROR THAT I GET--
(mx.rpc::Fault)#0
  description = "Could not find the ColdFusion Component com.testCFC."
  detail = "Please check that the given name is correct and that the component exists."
  errorID = 0
  faultCode = "Server.Processing"
  faultcode = "Server.Processing"
  faultDetail = "Please check that the given name is correct and that the component exists."
  faultString = "Could not find the ColdFusion Component com.testCFC."
  faultstring = "Could not find the ColdFusion Component com.testCFC."
  message = "faultCode:Server.Processing faultString:'Could not find the ColdFusion Component com.testCFC.' faultDetail:'Please check that the given name is correct and that the component exists.'"
  rootCause = (null)
