Well, your JSP will likely be calling some servlet when the user
clicks submit -- in that servlet you can do whatever file input/output
you want by using the java.io.* classes. You can always declare the
output method "synchroniz ed" too to prevent multiple people from
writing to the same file simultaneously. ..

I wonder what happens if there is an error, maybe
loose the whole file? Why not have a separate directory
for each day and individual files, one
for each response then cat them at the end of the day
to avoid this.
