Rodrigo, 

What you're asking for seems to be similar to a dependent object whereby
one object is dependent upon a master object. This is achieved via the
mapping descriptor. See the following for more information:

    http://www.castor.org/castor-one.html#Dependent-and-related-relationships

    and 

    http://www.castor.org/jdo-faq.html#Technical-questions 
    (see the following questions: 
        1. Can Castor automatically create/remove related objects?

        2. I call db.remove() on the dependent object and commit, but this doesn't 
work...)

I hope this helps.
