This is a very nice specimen of annotatiomania in the wild. When people not only confuse OO with relational, but also with XML. The “OOXMLational” model class, so to speak. Check this out:

@Entity
@Table(name = "Person", catalog = "TestDB", schema = "dbo")
@XmlRootElement
@NamedQueries({
    @NamedQuery(
        name = "Person.findAll", 
        query = "SELECT p FROM Person p"),
    @NamedQuery(
        name = "Person.findByPersonId", 
        query = "SELECT p FROM Person p WHERE p.personId = :pId"),
    @NamedQuery(
        name = "Person.findByPersonName", 
        query = "SELECT p FROM Person p WHERE p.personName = :pName"),
    @NamedQuery(
        name = "Person.findByPersonFamily", 
        query = "SELECT p FROM Person p WHERE p.personFamily = :pFamily"),
    @NamedQuery(
        name = "Person.findByPersonReference", 
        query = "SELECT p FROM Person p WHERE p.personReference = :pRef")})
public class Person implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Basic(optional = false)
    @NotNull
    @Column(name = "person_id", nullable = false)
    private Integer personId;

    @Size(max = 50)
    @Column(name = "person_name", length = 50)
    private String personName;

    @Size(max = 50)
    @Column(name = "person_family", length = 50)
    private String personFamily;

    @Column(name = "person_reference")
    private Integer personReference;

    @OneToOne(cascade = CascadeType.ALL, mappedBy = "person1", 
              fetch = FetchType.LAZY)
    private Person person;

    @JoinColumn(name = "person_id", referencedColumnName = "person_id", 
                nullable = false, insertable = false, updatable = false)
    @OneToOne(optional = false, fetch = FetchType.LAZY)
    private Person person1;

After years of fun with “Where’s Waldo”, we have a new game: “Where’s the Java Code”? Seen in the wild here:
