I have unsuccessfully tried to implement CMP using PK classes...
Normal implementation, public fields, overriding of the hash value etc.
Anyone got EJB 2.0, CMP, composite keys PK classes working ?
Thanks,
Daniel

I believe your last assertion is false. Any entity bean that has a
composed
key (that is, its key maps to more than one field in the persistence)
must
have its own PK class
check the specs

I am studying the book and I have played with some of the EJBs. There
are
some problems
1. I assume the code was written with the EJB 1.0 specifications because
it
is using some deprecated methods.
2. The author was using WebLogic to deploy the beans and there are some
major differences in the way you deploy the EJBs.

I am not an expert but from what I have noticed:
* CMBs do not need a PK class
* Bean-Managed persistence requires a PK class.
