ORM Question: Abstract Class

this simplification conceptual level, if like, can specify lot more details.

in nut shell, have objecta contains objectb. objectb nothing more shell, containing 4 objects: objectc, objectd, objecte , objectf.

objectb abstract class, others concrete, each corresponding table.

if tell hibernate objectb non persistent, ignore , not create of it's children, persistent. cannot tell it persistent either, because cannot point table , column link.

here more info:

• we cannot make design changes objects, because these reused in multiple applications.
• we considered using embedded attribute, work if objectb persistent, while others not. our case opposite.

 

so question is how handle non persistent object contains persistent objects

 

thanks
