Design questions on dependent objects

[Nikolaus Rumm]

Hello,   my questions are regarding dependent objects (persistent, fine grained java objects (not entity beans) that depend on an entity bean). I am looking for some "best practices".   * Is it recommended to use BMP or CMP entity beans for persisting dependent objects ? * Is it better to persist the dependent objects in the ejbLoad/ejbStore or in the set/get methods of the bean ? * How do I add the persistent objects to the transactional context of the entity bean ? The case is clear if the bean is part of a transaction and the isolation level is some kind of "write block", and thus the dependent objects are not accessible for write access to non transaction members, but what for optimistic locking ? Should I implement some kind of dirty flag mechanism in my dependent objects ?   Any help would be appreciated   Nikolaus
