I've added a meta extend tag to my class mapping file.

<hibernate-mapping>
<class name="com.xxx.yyy.SourceTest" table="SOURCE">
<meta attribute="extends">State</meta>

When I use the Eclipse plug-in to generate the Domain Code, I do not see that the resulting class extends anything.

public class SourceTest implements java.io.Serializable

In fact, the Eclipse plug-in seems only to use the hibernate.reveng.xml file which doesn't contain the meta tag. How do I get the tool to pick up the class mapping file for use in generating the Domain Code class?
