Given that you can successfully connect to that database from your
application from a different directory, the problem is most likely
related to security. Remember that you are *NOT* accessing the
database, but rather the fbserver process is on your behalf. This
process is most likely under a different user account. You will need
to make sure the user running the server process has read-write
permissions to the file.
