Sandbox security violation error on compiling FDS

Hi,
I am trying to compile am mxml using Remote Object locally using Flex SDK outside FlexBuilder.
I have used the command:
mxmlc -services="path\to\my\services-config.xml" -context-root=\ContextRoot FileName.mxml

I am getting the following error when I try to run the swf generated:

[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Security.Error error Error #2048: Security sandbox violation: http://localhost:9080/iReports/flexFiles/mxml/AdminServices.swf cannot load data from http://localhost:9080iReports/messagebroker/amf."
