Here are the current JOnAS status and plans regarding CMP.
The current version 2.0 of JOnAS only provides the limited features mentioned in the
EJB 1.1 specification, i.e., no persistent references between CPM entity beans, and no
polymorphism between CPM entity beans.
We, at France Telecom R&D, are working on a flexible and adaptable persistence layer
called JORM (for Java Object Repository Mapping). We plan to integrate JORM with JOnAS
this summer, and we should expect enhanced CMP before the end of the year.
Features of this new layer for CMP entity beans will include:
- persistent inter-bean references;
- polymorphism of bean classes;
- management of multi-valued attributes (lists, sets, arrays).
In a first step, only an implicit object-relational mapping will be provided.
Extensions will include a more flexible object-relational mapping, mapping to other
types of data sources (object databases).
PS: the JOnAS team apologizes for the late reply to this series of messages...
