Hi
If you create a composission between to enity beans (CMP version 2) and say that there is a cascade delete between the entities ie order - orderline if you remove the order the orderline's are delete but how is this done by the appserver ?

Finding each orderline entity and than a remove ?
A delete "outside" the appserver ?

This has great impact on performance so it would be good to know.

TIA
Jan
