Hi,
This is my proposal to solve JIRA issue HBX-577
"hbm2java for annotation from existing inheritance mapping"
I figured out how-to do "joined-subclass" and
"table-per-class-herarchy" but couldn't test it.
This solution relies on <meta> tag, example:
<class name="Nota" mutable="false"
table="NOTA"
schema="dbo" catalog="DATA"
discriminator-value="not null">
<meta
attribute="class-inheritance-type">single-table-per-class-herarchy</meta>
