Hi Philip,

if you try to use CVS version of castor you have to change your database.xml as follows:

<?xml version="1.0" ?> <!DOCTYPE databases PUBLIC "-//EXOLAB/Castor JDO Configuration DTD Version 1.0//EN" "http://castor.exolab.org/jdo-conf.dtd";>

<jdo-conf>
   <database name="aip9" engine="oracle" >
       <driver url="jdbc:oracle:thin:@142.3.26.15:1526:AIP"
                    class-name="oracle.jdbc.driver.OracleDriver">
           <param name="user" value="aiptest"/>
           <param name="password" value="aiptest"/>
       </driver>
       <mapping href="etc/mapping.xml" />
   </database>
   <transaction-demarcation mode="local" />
</jdo-conf>

Regards
Ralf

Hi all,

I just updated my castor jar using the daily snapshot source and I got
this error. I am migrating from 0.9.5.3. I am using j2sdk1.4.2_04. Below
is the stack trace, the database.xml, the mapping.xml, and even the
source code that all works with 0.9.5.3.

I checked out the jdo-conf.xsd and the mapping.xsd files but I don't see
any anomaly.

Mapping is XSLT generated so sorry for the formatting.

And the code that is getting executed :

       // Obtain all Rte objects from the database
       JDO jdo = new JDO();
       jdo.setDatabaseName("aip9");
       jdo.setConfiguration("etc/database-findev.xml");
   jdo.setClassLoader(getClass().getClassLoader());
       Database database = jdo.getDatabase();
       database.begin();
       Query queryRte = database
                       .getOQLQuery("SELECT v FROM db.finaixm.Rte v
WHERE verId=$");
       queryRte.bind(new Long(1));
       QueryResults queryResultsRte = queryRte.execute();
       TreeBidiMap RteUidMap = new TreeBidiMap();
       while (queryResultsRte.hasMore()) {
               db.finaixm.Rte element = (db.finaixm.Rte)
queryResultsRte
                               .nextElement();
               // Insert them as RteUid objects
               RteUid RteUid = new RteUid(
                               element);
               RteUidMap.put(RteUid, element.getRtemCodeRteId());
       }
       System.out.println("size : " + RteUidMap.size());
       queryResultsRte.close();
       queryRte.close();
       database.commit();
       database.close();
}

Thanks for any help,
Phil
