Object problems using java sockets

Question

I’m trying to pass the person object that was instantiated on the server to the client. But I’m not getting it. Below are the classes I used:

Server

public class ServidorTCPBasico {
public static void main(String[] args) {
    try {

        ServerSocket servidor = new ServerSocket(12345);
        System.out.println("Servidor ouvindo a porta 12345");
        while (true) {

            Pessoa pessoa = new Pessoa("José", "Zé");

            Socket cliente = servidor.accept();
            System.out.println("Cliente conectado: " + cliente.getInetAddress().getHostAddress());
            ObjectOutputStream saida = new ObjectOutputStream(cliente.getOutputStream());
            saida.flush();
            saida.writeObject(pessoa);
            saida.close();
            cliente.close();
        }
    } catch (Exception e) {
        System.out.println("Erro: " + e.getMessage());
    } finally {

    }
}}

Client

public class ClienteTCPBasico {
  public static void main(String[] args) {
    try {
      Socket cliente = new Socket("127.0.0.1",12345);
      ObjectInputStream entrada = new ObjectInputStream(cliente.getInputStream());
      Pessoa pessoa = (Pessoa)entrada.readObject();
      JOptionPane.showMessageDialog(null,"Dados da pessoa:" + pessoa.toString());
      entrada.close();
      System.out.println("Conexão encerrada");
    }
    catch(Exception e) {
      System.out.println("Erro: " + e.getMessage());
    }
  }
}  

Classe Pessoa

public class Pessoa {

    String nome;
    String apelido;

    public Pessoa(String nome, String apelido) {
        this.nome = nome;
        this.apelido = apelido;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getApelido() {
        return apelido;
    }

    public void setApelido(String apelido) {
        this.apelido = apelido;
    }

    @Override
    public String toString() {
        return "Pessoa{" + "nome=" + nome + ", apelido=" + apelido + '}';
    }
}

When I spin the class ServidorTCPBasico everything OK, but when I turn the class ClienteTCPBasico of the following error:

Error: Connection reset

I used as an example to develop this code the article from Devmedia
I used the classes of the same name only replaces the Date class with the Person class. I intended to pass an object created by me using socket , but unfortunately it did not work! Where there is an error in this application?

I think the mistake is in using the class ObjectOutputStream to read some primitive type, but I’m not sure.

Answer 1

try to implement the interface Serializeble in your class Pessoa, when you implement this interface your class becomes "serializable".
