Unless the file is at an already known, absolute location, you need some
way to determine the correct path to it. If it's part of your WAR, and
the WAR could have been deployed anywhere (according to where the
container is installed, etc.) then you will need a way to figure out the
correct path to load.
You can place it anywhere you like within the WAR and access it using
getRealPath(). However, if the container the webapp is running in
doesn't expand WAR files, that might not work. Another alternative is to
place the file in the classes and load it via getResource(). Or, install
it to a known location (/etc, C:\Program Files\Your Application\, or
whatever) so you can reference it with an absolute path.

Hi Laurie. Actually, I am not using any method to determine the path of
the file. Should I be doing that? In general, where should one place
files used for I/O within the WAR structure? Thanks for your help.

It's hard to help without seeing the code, but you are probably
specifying an incorrect path to the file. Are you using getRealPath()
[1] to figure out the real file location?
