I'm very new to this. This is the first time I'm using mysql and servlet. I
might be doing a lot of mistakes. I realized that I should not use Microsoft
Works Database. How can I actually create the database name, table and its
field using mysql? In which directory should I put the database? Please
explain. Hoping for a reply. I really hope this simple program can run today.
Thank you.

Hi,
This is getting more confusing, you mentioned earlier that you're using
MySQL but now it is a Microsoft Works Database. Hmmm perhaps i'm missing
something?
Anyway, if the database you're using is something like an Access
database, you'll just need to use the correct driver and point the URL
to your database file. Can't help you here coz i never tried that before
(Access is like from another world to me). Perhaps you should try other
mailing list, and not Tomcat's.
