Hello The load method that takes the instance of the Object seems to be what I wanted, however it still creates a new instance of my class. Here is my method...Is this correct? public Object doLoad(Database db, Object pk, Object genObj)
throws Exception
{
try {
genObj=db.load(genObj.getClass(),pk,genObj);
}
catch (PersistenceException pe) {
log4jCat.error("DB load failed.", pe);
db.rollback();
}
return genObj;
} Here is my result, notice how the repeated "Loading class" appears!!! INFO [AWT-EventQueue-0] ( Example.java:314) - Begin UPDATEINFO [AWT-EventQueue-0] ( MapCable.java:39) - new instance!INFO [AWT-EventQueue-0] (Example.java:328) - getCable called INFO [AWT-EventQueue-0] (MapCable.java:39) - new instance!

Hi Manuel,
have a look at:
http://castor.codehaus.org/api/org/exolab/castor/jdo/Database.html#load(java.lang.Class,%20java.lang.Object,%20java.lang.Object)
if this is what you wanted to.
Regards
