I need some way to reproduce your issue, preferably something only using plain serialization.

Things that would change default behavior on serialization (to help you identify some pattern)

- readResolves
- private write or readObject
- non serializable classes not implementing default constructor
- adding something not supposed to be in the serialization tree (like socket or connection)

I found this on the log:

DEBUG: describeObject::Calling writeReplace for br.gov.go.tj.execpen.entidades.Cidade$$EnhancerByCGLIB$$652dbb34

I'll investigate a little more.

What I meant was...

you could reproduce a JbossSerialization failure by just playing with your classes, without having to play with MyFaces in a testcase at al.

I will be able to fix this for you, as long as you create the testcase.

PS: If you want to send me this in private it's okay. (I also speak Portuguese BTW as I'm brazilian). In case you do let me know if I can include it as part of the testcases, or if it's something confidential for you.

Clebert,

I'm almost sure that Cidade class reach this point as null reference:

(ObjectDescriptorFactory.java, line 191) metaData = ClassMetamodelFactory.getClassMetaData(obj.getClass(),cache.isCheckSerializableClass());

I need to know what caused it.
A regular null reference should be treated without any problem.

This is my Cidade.java:

package br.gov.go.tj.execpen.entidades;

import java.io.Serializable;

public class Cidade implements Serializable
{

    static final long serialVersionUID = 1l;
	
    private Integer codigo;
    private String   nome;
    private String   uf;

    public Cidade() {

    }

    public Integer getCodigo() {
        return(codigo);
    }

    public void setCodigo(Integer codigo) {
        this.codigo = codigo;
    }

    public String getNome() {
        return(nome);
    }

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

    public String getUf() {
	return uf;
    }

    public void setUf(String uf) {
	this.uf = uf;
    }
}

and when the error happens all fields are null.

Clebert,

Sorry, i checked here and this is a Hibernate related issue that was causing that error.

The problem won't be on Cidades. The problem will be on the class holding Cidades.

Again... can't you send me the whole thing in private?


clebert.suconic at jboss.com

I won't of course publish anything.

now that I spent some time on it I'm curious... :-)

Can you point me what's the issue?

[rpa_rio <do-...@jb...>]

Well, i have two methods on Hibernate that loads a persistent instance from database, the first method Session.load that i was using retrieve an existing persistence instance but this isn't appropriate in case where i need check if the instance exists in database.

So, when i use this method and the instance doesn't exists in database, then i get a instance with null values in all instance fields and this was causing the error on jboss serialization.

Now i'm using Session.get, this method returns null if the instance doesn't exists in database and when  jboss serialization executes the code everything works fine because you do some checks about null pointers.
