I'm enjoying (mostly) getting JSPWiki to work with mysql on Mac OS X 10.3.  I updated the [DatabaseProviderPatch] to fix a couple of bugs, and things are working OK now.  I'm using:
* JSPWiki 2.0.52
* Tomcat 4.1.24
* MySQL 4.0.15 
Had problems getting Tomcat 4 plugged into the Apache 1.3 that comes with the OS, so I use tomcat directly (port 8080). Mac installs for both MySQL and Tomcat came from [http://www.serverlogistics.com/].
