I use the following hbm to get table per concrete class

<hibernate-mapping >

<class name="model.Activity" abstract="true" >
<id name="objectId" type="int" column="OBJECTID">
<generator class="hilo">
<param name="table">hi_value</param>
<param name="column">next_value</param>
<param name="max_lo">100</param>
</generator>
</id>

<property name="name" column="NAME" />

<union-subclass name="model.Event" table="Event">
<property name="description" column="DESCRIPTION" />
</union-subclass>


<union-subclass name="model.Task" table="Task">

<property name="type" column="TYPE" />
</union-subclass>

</class>


</hibernate-mapping>

But I end up with 3 tables. the super class Activity gets its own table with column 'name'. why does I get just two tables for just the two subclasses?

Hi

Are you sure that your model.Activity is a abstract ?

So how would you end up a table Activity. If there is a table mapped with model.Activity you should mention it in . and remove your abstraction.

(Don't forget to rate if helps)

you are right on there.

there is a discrepancy between my hbm and the java class, which does not have the abstract qualifier.

Thanks for the tip.
