Couldn't establish a connection to 'ColdFusion' from Flex
 

Hi, I developed a Flex application which communicates with ColdFusion to send a mail to a mail address. When i run that Flex application it shows this error

[faultCode:InvokeFailed faultString:'[MessagingError message='Destination 'ColdFusion' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']' faultDetail:'Couldn't establish a connection to 'ColdFusion'] please give the answer. Thanks in advance.
