RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: http://localhost:8080/WebContent/messagebroker/amf'"
can be resolved in a single step..
First ensure you don't modify anything in the service config file.. Leave the poor guy alone.
Then right click on your project ---> go to properties -> flex server ==> servercontextrooot -->
Give it the same name as your project
if your project is Fantastico
your server root will be
/Fantastico..
Now you are good to go on any server any place blazeDs or LCDS no issue
