[flexcoders] Flex app fails when moved to server hosting web services

[wubac1]

I have a Flex application that runs fine from my desktop.  When I move the 
files to a virtual machine that already hosts the web services for the app, it 
no longer works as expected.  Now, when the app creates a WebService and calls 
an operation, I see that the WSDL if located and downloaded, but the operation 
never executes.  Via Charles, I see a "404 Not Found" for URL 
http://schemas.xmlsoap.org/crossdomain.xml.  While I do not call any services 
at xmlsoap.org, it is part of the namespaces in my web services.  Any 
suggestions as to correcting this problem on the VM?
