If you have 2 computers and downloaded j2ee and the jdk
and get www.mysql.com ( or use a simple flat text file
and create your own text parser ) with your 2 computers you can
make your own 3-tier mini client middleware server program.
mysql is free and open source!!! also to make your prototype
more real get apache and the xml and jsp plugins for apache
and your webserver will be apache with jsp and xml ( with ejb for the middletier )
your database sql and your client a browser on the 2nd computer
www.linksys.com has cheap networking kits for < 120 $ and they
are very high quality. they work with all versions of windows
and linux.
