Just to try to review the requirements: prim-key-class is *always*
required, and prim-key-field is required for CMP entity beans that use a
simple primary key.
For CMP beans that use a complex primary key, all the fields of
the primary key must be public and non-static. They must have the same
names as fields in the bean implementation class, and those fields must
also be public and non-static. The PK fields in the bean implementation
must be declared as CMP Fields in ejb-jar.xml, as well.
You should not declare a field in the bean implementation that has
the type of the bean's primary key - you must instead use multiple
individual fields that correspond to the fields of the primary key, as
above. Or at least, if you do declare such a field, it cannot be a
container-managed field and it does not replace the individual
container-managed fields that are required.
Let's see... Your primary key class must be serializable and
public. That's about all I can think off off the top of my head, but the
spec is of course the final authority.
I think there may be a few things to add to the verifier here.
I'll go have a look.
