Ned thanks! I got a bit further but I continue to get and exception from

Below is the modified database.xml file I am using.
<!DOCTYPE databases PUBLIC "-//EXOLAB/Castor JDO Configuration DTD Version
1.0//EN"
"http://castor.exolab.org/jdo-conf.dtd";>
<database name="CASTORTST" engine="mysql" >
<driver class-name="org.gjt.mm.mysql.Driver"
url="jdbc:mysql://localhost/CASTORTST" >
<param name="user" value="" />
<param name="password" value="" />
</driver>
<mapping href="ProductGroup.xml" />
</database>
The ProductGroup.xml is unchanged.

javax.sql.DataSource
Well, the jdbc driver isn't a data-source. So you should use the
<driver> instead of <data-source> in database.xml Like this:
<driver class-name="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@host:port:SID">
<param name="user" value="scott" />
<param name="password" value="tiger" />
</driver>
See http://castor.exolab.org/database-conf.html for more info
