Re: [castor-user] MappingException: Could not find the class...

Jim,
Did you make sure the directory which contains your class is part of 
your classpath?

I'm new to castor and trying to run a little test against mysql, from 
the tutorial at java boutique but getting a MappingException that I 
don't understand. This is my mapping.xml:

<mapping>
    <class name="Media" identity="id">
        <map-to table="media" />
        <field name="id" type="integer">
        <sql name="id" type="integer"/>
        </field>
        <field name="type" type="string">
        <sql name="type" type="char" />
        </field>
    </class>
</mapping>
the Media class is in the same dir as mapping.xml & database.xml & my 
TestCastor class (no packages involved) which contains the code which 
initialises JDO:

      JDO jdo = new JDO("mydb");
      jdo.setConfiguration("database.xml");
evrything compiles OK but running TestCastor gives me this error:
log4j:WARN No appenders could be found for logger 
(org.exolab.castor.jdo.engine.DatabaseRegistry).
log4j:WARN Please initialize the log4j system properly.
