Is it possible to define a bidirectional one-to-many relationship using
a join-table?

I know that JPA1 says quite clear for one-to-many relationships: if
bidirectional than join-column, and if unidirectional than join-table.

Does OpenJPA support bidirectionality with a join-table (as it supports
unidirectionality with a join-column)?

Kind regards,
Frank
