Apologies if this is boneheaded, I'm a total newbie..

I have three classes

Booking 1---* BookedOrder 1---* BookedOrderLine

I need a Set member variable in Booking called bookedOrders, and a Set member variable in BookedOrder called bookedOrderLines that are auto populated.
I find it's not possible to have a collection within a collection, so I thought the BookedOrderLine.hbm.xml would contain something like this


And the BookedOrder.hbm.xml would contain this


but it doesn't look like auto population would occur..

Is there a better, more elegant solution? If it's documented and I've missed it I'd be grateful for a pointer in the right direction!

Many thanks

did you try to use middlegen? got the HBM files from your database, if you don't want to use SQL to build the database , then you can use Xdoclet to generate HBM files from Java Classs.

Middlegen not right for me, I want to generate the SQL from the object model. Will try xdoclet and see what it gives me.
Thanks
