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

Thanks, but since there are no packages involved <class name="Media" is fully qualified, isn't it? I tried setting it up with a package structure as you suggest and get the same error. I also tested that the main class can find Media (with or without packages), which it can...

package com.me.Media;

<class name="com.me.Media"

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.
