What JSP/servlet container are you using?
The container usually won't share the same classpath as you. If you are using Tomcat, you can just throw a copy of the the .jar into $TOMCAT_HOME/lib and restart Tomcat.

Thanks, but ...
I'm not using a servlet container, I was experimenting with JMeter ( http://jakarta.apache.org ) and thanks to a tutorial about Postgresql ( http://www.fankhausers.com/postgresql/jdbc/welcome.html ) I've discovered that:
- NO CLASSPATH is the best way, just put the driver in /usr/java/jre/lib/ext - MySQL.com documents regarding jdbc simply SUCKS!!!! Thanks again for your help.

The puzzle is solved when you understand what classpath is explicit and implicit with the environment you are running on.
For general JDBC, you can't beat java.sun.com for tutorials and javaranch.com for people to pester.
