You need to provide the fully-qualified class  name for the driver you want to
use. For example, there is a good driver
for mysql  at http://mmmysql.sourceforge.net/ . If you download that driver then
you would have to replace
"myDriver.ClassName" with "org.gjt.mm.mysql.Driver". I don't know what the
driver for Oracle is called though...check
the documentation for Oracle.
