queries in HQL editor:

select e from Equipment as e
  | 
  | select a from ApplicationSetting a

any idea why this is happening?  The entities exist:

@Entity
  | @Table(name = "Equipment", uniqueConstraints = @UniqueConstraint(columnNames = "SerialNumber"))
  | public class Equipment implements java.io.Serializable {
  | ...
  | }

Is something required in orm.xml (I thought orm.xml was optional if you use annotations in your JPA entity classes).
