Hello, my problem is: I can not use services published in Flex or ArcMap. The only clue I have is that Flex showed me an error saying crossdomain.xml was not found . pleaseeeeee help me
For creating a crossdomain.xml file, check crossdomain.xml , although I am not sure why it's not getting displayed in ArcMap. Can you view the services in any other application (e.g. ArcGIS Explorer for Desktop)?
