To read file "foo.txt" from the document root, try this:

    InputStream is =

If you want to read it as characters, you can wrap an InputStreamReader around

    InputStreamReader isr = new InputStreamReader(is);

This works no matter what directory your webapp runs in.  As an added bonus, it
will also work in servlet containers that don't store your webapp as a directory
at all (for example, if it runs the app directly out of a WAR file).
