[jboss-user] [EJB 3.0] - <ENTITY> not mapped

Hi, I using a InheritanceType.SINGLE_TABLE and try to query this, but without success. Here my abstract superclass @Entity | @Name("person") | @Inheritance(strategy = InheritanceType.SINGLE_TABLE) | @DiscriminatorColumn(name = "PERSON_TYPE", discriminatorType = DiscriminatorType.STRING) | @SuppressWarnings("unused") | public abstract class Person extends BaseEntity{ | | @Id @GeneratedValue | @Column(name = "PERSON_ID") | private Long id; | ... and the extended subclass @Entity | @DiscriminatorValue("US") | @Name("user") | public class User extends Person | ..... { Now when I use to query ("from person where PERSON_TYPE='US' order by name, forename") the user class the following exception is thrown Caused by: org.hibernate.hql.ast.QuerySyntaxException: person is not mapped [from person where PERSON_TYPE='US' order by name, forename] All tables are created when the app is deployed. Using JBoss-4.0.5.GA with Seam 1.1.1 Any idea whats wrong in my app? Thanks Andreas View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4009518#...
