      There is no word in documentation how to do that, please somebody tell me how to audit the embedded classes?

      I use following example: http://www.mkyong.com/hibernate/hibernate-many-to-many-example-join-table-extra-column-annotation/

       

      Co My code is:

       

      @Entity
@Table(name="projects_project")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="disc_type", discriminatorType=DiscriminatorType.STRING)
@DiscriminatorValue("project")
@Audited
public class Project implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue
    @Getter @Setter
    private int id;
    (...)
    @OneToMany(targetEntity=ProjectParameter.class, mappedBy="pk.project", cascade=CascadeType.ALL)
    @Getter @Setter
    private List<ProjectParameter> projectParameters = new ArrayList<ProjectParameter>();

       

      @Entity
@Table(name="projects_rel_project_parameter")
@Audited
@AssociationOverrides({
    @AssociationOverride(name="pk.project", joinColumns=@JoinColumn(name="project_id")),
    @AssociationOverride(name="pk.parameter", joinColumns=@JoinColumn(name="parameter_id"))
})
public class ProjectParameter implements Serializable {

    private static final long serialVersionUID = 1L;

    @EmbeddedId
    @Getter @Setter
    private ProjectParameterPK pk = new ProjectParameterPK();

    @Getter @Setter
    private double value;

    public Project getProject(){
        return pk.getProject();
    }

    public void setProject(Project project){
        pk.setProject(project);
    }

    public Parameter getParameter(){
        return pk.getParameter();
    }

    public void setParameter(Parameter parameter){
        pk.setParameter(parameter);
}

       

      public class ProjectParameterPK implements Serializable {

    private static final long serialVersionUID = 1L;
    @ManyToOne
    @Getter @Setter
    private Project project;
    @ManyToOne
    @Getter @Setter
    private Parameter parameter;

}

       

      I got exception:

       

      Caused by: org.hibernate.MappingException: Unable to read the mapped by attribute for projectParameters in pl.proedims.project.model.ProjectParameter!
