(...sorry for my english...)

I have a table PARENT P with
P.ID
P.DESCRIPTION

and I must map an indexed collection with a list in a table CHILD C.
C.ID
C.INDEX
C.VALUE

what is the best mapping solution for save/update the parent and the child so that the P.ID is assigned by a oracle sequence
and C.ID is assigned by P.ID (the same sequence number).
How can I write the java code without managing the sequence number
(I want let do the work to oracle and hibernate).

It is possibile to assign an automatic INDEX value taken from the list index?

Thank you very much.

This is a very basic Question. Every thing you asked is explained very well in hibernate reference document.

I red the entire reference documentation (release 2.1 and 3.0) word by word, and there is no examples of parent/child with a indexed list automatically assigned.
I red the "hibernate in action" book and also "pro hibernate 3".
I want to automatically assign a row-index for the children entity.

Not sure if it will work with one-many but you can map a primary key to be the same as a foreign key. See section 6.1.4.1 http://www.hibernate.org/hib_docs/v3/re ... tml_single
