> FIrst, I created an EJB3 Java classes using:
> 	<hibernatetool >
> 		<jdbcconfiguration configurationfile="src/hibernate.cfg.xml" revengfile="hibernate.reveng.xml" packagename="de.unilog.ejb3"/>
> 		<hbm2java destdir="src-ejb3" ejb3="true"/>
> 		<hbm2cfgxml destdir="src-ejb3" ejb3="true" />
> 	</hibernatetool>
> Then, I tried to let Hibernate Tools parse it's own output to generate DDL:
> 	<hibernatetool>
> 		<annotationconfiguration configurationfile="src-ejb3/hibernate.cfg.xml" />
> 		<hbm2ddl update="true" export="true" outputfilename="demo.ddl" delimiter=";" destdir="."/>
> 	</hibernatetool>
> However, I got the following error:
> BUILD FAILED
> C:\Daten\Projekte\hibernate-tools\build2.xml:4: org.hibernate.AnnotationException: Collection has neither generic type or OneToMany.targetEntity() defined: de.unilog.ejb3.Kunde.bestellungs
