Hi
I am trying to get a simple example of Castor JDO running. I am
using the following database and mapping files:
<!DOCTYPE databases PUBLIC "-//EXOLAB/Castor JDO Configuration DTD Version
1.0//EN"
"http://castor.exolab.org/jdo-conf.dtd";>
<database name="CASTORTST" engine="mysql" >
<data-source class-name="org.gjt.mm.mysql.Driver"
url="jdbc:mysql://localhost/CASTORTST" >
<params user="" password="" server-name="localhost" />
</data-source>
<mapping href="ProductGroup.xml" />
</database>
<!DOCTYPE databases PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.exolab.org/mapping.dtd";>
<mapping>
<!-- Mapping for ProductGroup -->
<class name="myapp.ProductGroup"
identity="id">
<description>Product group</description>
<map-to table="prod_group" xml="group" />
<field name="id">
<sql/>
<xml node="attribute"/>
</field>
<field name="name">
<sql dirty="check" />
<xml node="text" />
</field>
</class>
<mapping>
I get the following exception when I call jdo.getDatabase();
java.lang.IllegalStateException: Data source class name does not extend

Anyone have any ideas what would cause this exception?
