THIS WORKS NOW!
Thanks a lot.
I'm so fascinated about the great possibilities of servlets :)
I've thousands of ideas to implement.

Betreff: Re: Tomcat and MySQL
I have MySQL working fine with the driver you mention below (version 2.0.4)
by putting the library for it (the jar file) into the WEB-INF/lib
directory, where it belongs.
If it doesn't work for you there, you can try the $TOMCAT_HOME/lib
directory. Some things (like JCE 1.2.1) only will work from there due to
problems in tomcat.
I use Tomcat 3.2.1.
