JPAContainer Addressbook Demo - Internal key

Flow
1

Hi:

I am modifiying the JPAContainer AddressBook Demo with MySql and I have a couple of classes (Empresa and Autor)


@Entity
public class Empresa {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long idEmpresa;

    @NotNull
    @Size(min = 2, max = 50)
    private String razonSocial;
    @Size(min = 2, max = 50)
    private String repLegal;
    private String direccion;
    private String ciudad;
    private String telefono;
    private String lookFeel;
    
    @OneToMany(mappedBy = "empresa")
    private Set<Autor> containerAutores;

And Autor:


@Entity
public class Autor {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long idAutor;
    @NotNull
    @Size(min = 2, max = 30)
    private String autor;

In attached files are the source and the output screen

how can display the value of razonSocial in Empresa in place of internal key (com.vaadin.demo.jpaaddressbook.domain.Empresa@1341b06) ?

thanks in advance
