Hi Dirk,

It depends, what you want to achieve:

JPA targets relational databases and embedded objects don't have
an identity on their own and are supposed to be mapped to the owners table
(single refs), or
the respective tables to be joined to the owners row (col/maps refs).

So polymorphism does not work, if this is, what you wanted to do, then the
answer would be "no".

If you don't plan to use polymorphism and only derive them for convenience,
then the answer would be "yes",
as an Embeddable class adheres to the same rules like an Entity (except
marked as embeddable rather then entity)
