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