Why you do not use the ojvm script for running your application? This script
sets all needed jars and environment variables need to run ozone applications.

Do not use XML.Store for _large_ XML files. If you want to use this class you
have to have installed a lot of RAM, because each DOM tree is build in memory
twice for serialization and deserialization.

Do you get any error on server side? In the last two mails users reported
problems with WizardStore.

Run XML.Load to load the stored XML file. Is this file complete?
