Daniel,
Your mapping would require support for a table per concrete entity class
strategy, that is optional in the spec, and GlassFish doesn't support it.
But you are not specifying the inheritance strategy at all, which makes
it a single table per class hierarchy by default. It might be a bug in
the 9.0 FCS build (aka v1 b48), or the fact that you specify a different
table name for each concrete class, that causes inheritance to be ignored -
you can try the latest promoted build for that part, but again, your mapping
is currently not supported.
On the other hand, I don't see a difference between a `brides` and a `grooms`
table, so adding a descriptor column to the single `brides_grooms` table will
simplify the schema, use the default mapping, and should be correctly supported
by the code.
thanks,
-marina
