Composite/Aggregate Entity Bean Pattern
[161 byte] By [pxmartin] at [2007-9-27 2:53:29] 
Can the Composite/Aggregate Entity Bean Pattern only be implemented for Bean ManageredPersistence ? Is this the case for EJB1.1 and EJB2.0 ?
It is the case for EJB 1.1, you could use OR mappings tools -for Dependant Value Classes.In EJB 2.0 you would use Container Managed Relationships.

No, you could also use CMP by applying deep copy semantics.
However applying the Composite Pattern directly to EJB's without applying ValueObject semantics is generally a bad idea. The granularity is way to small.
