[ojb-users] mapping multiple objects transparently to a single table

[Andrew G. <Gee...@do...>]

I was wondering if it is possible to map multiple objects to a single table
transparently.

For example: Object A maps to table T. Object B contains a reference to
object A and also maps to table T. How can I set up the repository.xml file
so that when I call

broker.store( B );

object A is also stored? The problem I am running into is that the database
complains that the id column is specfied more than once in the INSERT
statement

Can this even be done? If it can, a short example would be wonderful.

Thanks
Andrew
