    <p>I have an abstract superclass "RessourceMaterielle" and an entity derived class "Vehicule". I have a 1 to 1 mapping between the sperclass and another class "Localisation". The abstract superclass is not represented in the database. I want the mapping between the superclass and the Localisation to be inherited by the derived class, so that Hibernate sees a mapping between Vehicule and Localisation. Is that possible?</p> <p>Superclass:</p> <pre><code>@MappedSuperclass public abstract class RessourceMaterielle extends ObjetMetier { private String nom = null; private Localisation localisation = null; @Column(name = "`NOM`") public String getNom() { return this.nom == null ? null : new String(this.nom); } public void setNom(String nom) { this.nom = new String(nom); } @OneToOne(cascade={CascadeType.ALL}) @JoinColumn(name="`LOCALISATION`") public Localisation getLocalisation() { return this.localisation == null ? null : this.localisation.clone(); } public void setLocalisation(Localisation localisation) { this.localisation = localisation.clone(); } public RessourceMaterielle(){ } } </code></pre> <p>Vehicule:</p> <pre><code>@Entity(name = "VEHICULE") @Table(name = "`VEHICULE`") public class Vehicule extends RessourceMaterielle { public Vehicule() { } } </code></pre> <p>Localisation:</p> <pre><code>@Entity(name = "LOCALISATION") @Table(name = "`LOCALISATION`") public class Localisation extends ObjetMetier { private double lon = -1111; private double lat = -1111; private RessourceMaterielle ressourceMaterielle; @OneToOne(cascade = { CascadeType.ALL }, mappedBy = "localisation") public RessourceMaterielle getRessourceMaterielle() { return (RessourceMaterielle) (this.ressourceMaterielle == null ? null : this.ressourceMaterielle.clone()); } public void setRessourceMaterielle(RessourceMaterielle ressourceMaterielle) { this.ressourceMaterielle = ressourceMaterielle; } @Column(name = "`LON`") public double getLon() { return this.lon; } public void setLon(double lon) { this.lon = lon; } @Column(name = "`LAT`") public double getLat() { return this.lat; } public void setLat(double lat) { this.lat = lat; } public Localisation() { } public Localisation(double lon, double lat) { this.setLon(lon); this.setLat(lat); } } </code></pre> <p>When I run a test that persists a Vehicule into the database I get the following error:</p> <pre><code>org.hibernate.AnnotationException: Unknown mappedBy in: com.organisme.model.localisation.Localisation.ressourceMaterielle, referenced property unknown: com.organisme.model.ressource.RessourceMaterielle.localisation </code></pre> <p>Is there any solution?</p> <p>Regards.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
