I don't understand "try to see if Torque can locate that older driver". How
do I do that?

No, I"m not saying use the older jdbc driver cause
that's obsolete now. I was saying that just try to see
if Torque can locate that older driver which should be
located in the same jar that you have. If none could
be located then check your classpath once again. The
older driver was org.gjt.mm.mysql.Driver.
