According to:
http://code.google.com/appengine/docs/java/jrewhitelist.html
The FileInputStream should be a white-listed reader function. Are you having this access problem in the development environment (in which case what is your development environment? There have been reports of similar issues with people using the Eclipse plugin that resolved after restarting eclipse, cleaning, and re-building the project), or in a deployed application?
How are you specifying the path to your file? Can you include code?
