I have the

you need to unzip it and add the include *jar* to your libraries (not the whole zip)

I have the answer. After a long dig through Google, I finally found a bit of information that solves my problem on Leopard and Tiger. I found that the CLASSPATH doesn't work at all (at least for me) and all that needs to be done is to copy the mysql JDBC connector to /Library/Java/Extensions. As soon as I did that, my java program could connect to my MySQL database and I was off and running.

The CLASSPATH is the common answer here but it did not work. Only when I added the mysql JDBC connector to /Library/Java/Extensions did it work.

His last post may have hinted at that but not at enough detail to show me how to fix it as a novice.
