Good afternoon,

I am creating a project using JSF , CDI , Bootstrap and Hibernate .

I would like to know how to work with the following problem, I created a set of classes to represent a person entity física or jurídica . The structure is as follows:

@Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="tipo", discriminatorType=DiscriminatorType.STRING, length=1)
@Named("clientePojo")
public abstract class Cliente extends Persistent {

    public enum TipoCliente {

        FISICA('F', "Física"), 
        JURIDICA('J', "Juridica");

        private final char tipo;
        private final String descricao;

        private TipoCliente(char tipo, String descricao) {
            this.tipo = tipo;
            this.descricao = descricao;
        }

        public static TipoCliente valueOf(char sigla) {

            switch (sigla) {
            case 'F':
                return TipoCliente.FISICA;
            case 'J':
                return TipoCliente.JURIDICA;
            default:
                return null;
            }
        }

        public char getTipo() {
            return tipo;
        }

        public String getDescricao() {
            return descricao;
        }
    }

    @Column(insertable=false, updatable=false)
    private String tipo;

    // getter e setter  
}

@Entity
@DiscriminatorValue(value="F")
public class ClienteFisico extends Cliente {

    private String nome;

    private Date dataNascimento;

    private String identidade;

    private String cpf;

    // getter e setter
}

@Entity
@DiscriminatorValue(value="J")
public class ClienteJuridico extends Cliente {

    private String razaoSocial;
    private String nomeFantasia;
    private String cnpj;

    // getter e setter
}

How should I handle this case to instantiate in bean ? Since the registration form you select if the type is physical or legal.

java jsf hibernate cdi

Error: "update were reject because the remote work that you do not have locally" How can I execute this query with Laravel 5?

Retrieve if the type of person to be registered by the form is Physical or Legal and instantiate an object of the type you wish.

Ex:

if (TipoCliente.FISICO == form.getTipoPessoaValue()) {
   ClienteFisico cliente = new ClienteFisico();
   // insira seus setters aqui
}

You can instantiate an object from a child class, and even then, set attributes that are represented by the superclass (as in the case of Client and Physical Client).

Note: It is recommended that you do not manipulate entity data directly. To do this, use the Data Transfer Objects or DTO's. You would have something like "ClientDTO" and etc.
