Hi, I tried to reproduce the problem with Hibernate and OpenEJB.
The previous message in the log file was: > org.apache.openejb.OpenEJBException: createApplication.failed > [D:\JavaProg\MySamples\EJB\Sample5\JEEMavenProject2\EjbServiceCore\targ > et\classes]: null Now I get: org.apache.openejb.OpenEJBException: createApplication.failed [D:\JavaProg\MySamples\EJB\OLD\JEEMavenProject2\EjbServiceCore\target\classes]: org.hibernate.AssertionFailure: Table PERSONENT not found: Table PERSONENT not found In that case the problem is with annotation processing and database schema creation: @Entity @Table(name="ACCOUTENT") @Inheritance(strategy=InheritanceType.JOINED) @DiscriminatorColumn(name="typ", discriminatorType=DiscriminatorType.STRING) @SecondaryTable(name="PERSONENT",[EMAIL PROTECTED](name= "ID")}) public class PersonAccountEnt implements Serializable I found that inheritance JOINED and SecondaryTable does not work with Hibernate. So the problem is not with OpenEJB (I think). I don’t know why I get "null" in original project. Can it be the same problem or a different one?
