Dear Werner,
It is okay...
I have the src downloaded and I have collated my problem with the myapp
example in the src. I think myapp example is very simple and direct and it
does not explain well on my question. My problem looks more complicated
because of the extra wrapper tags in the XML data, eg:
<developers>
<developer id="1">developer1 </developer>
<developer id="3">developer2 </developer>
<developer id="5">developer3 </developer>
</developers>
OR
<addresses>
<address id="1">address 1</address>
<address id="2">address 1</address>
</addresses>
I think you will understand better on the generated source based on the
schema for xml data above. Based on my message entitled 'My Castor Usage'
description, I think can understand my problem better...
I hope that you can really give me a hand in this matter. I did send Bruce
Snyder the same problem, I think i had sent it in HTML format, and the
message scrambled by the mailing list system. He didnt reply since then.
I am helpless, and I hope that you can really help. I would appreciate it
very much.
Cheers,
Ng Keng Yap

Oops, sorry for the misunderstanding. To be able to persist a hierarchy of
Java objects you'll need to create a mapping file for this purpose. Have a
look
at http://castor.exolab.org/jdo-mapping.html for a syntactical explanation
of the mapping file, and don't hesitate to come back if you have any
questions. Alternatively, if you obtained the sources as well, have a look
at src/tests/jdo/mapping.xml to see some sample mappings.
