I have a flex/lcds/java application that attempts to download a zip file called
GeneratedTestProject.zip (using FileReference in the Flex app) that I generate
at runtime on the server (in the Java app). The zip file is generated fine, but
the following error is thrown by the Flash Player when I click the save button
of the file download dialog.
Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.

****Note: I am able to download a separate zip file (CodeGenerator.zip) that
already exists on the server before the app starts up and was not generated at
runtime. So it seems as though the download script and the permissions are
setup correctly, but I am missing something. Please help. Thanks!
