When I generate Java Classes with hbm2java and I use the param "generate-concrete-empty-classes" the concrete classes are overridden.

Is it possible to preserve existing, concrete classes?

My config-file:

<codegen>

<generate prefix="Base" renderer="net.sf.hibernate.tool.hbm2java.BasicRenderer"/>


<generate renderer="net.sf.hibernate.tool.hbm2java.BasicRenderer">
<param name="generate-concrete-empty-classes">true</param>

<param name="baseclass-prefix">Base</param>
</generate>

</codegen>


I use Hibernate 2.1.4 and the latest snapshot of Hibernate-Ext (20040719).


TIA
