Still getting SerializationException

[przemek lewandowski]

Hi Im new to BeanLib, I have read the instructions about HibernateBeanReplicator, but Im stiil getting SerializationException ;/ 

Could Somebody help me ?

these are my entity clasess:

=============================================

package pl.dbg.prawnicy.shared;

import java.io.Serializable;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;

@Entity
@Table(name = "Uzytkownik")
@SuppressWarnings("serial")
public class Uzytkownik implements Serializable
{
@Id
@GeneratedValue
@Column(name = "userId")
private Integer userId;

@Column(name = "Login", nullable = false, unique=true)
private String login;

@Column(name = "Haslo", nullable = false)
private String haslo;

@Column(name = "Hash")
private String hash;

@Column(name = "Imie", nullable = false)
private String imie;

@Column(name = "Nazwisko", nullable = false)
private String nazwisko;

@Column(name = "Mail")
private String mail;

@Column(name = "Telefon")
private String telefon;

@OneToMany(mappedBy="user")
@Cascade({CascadeType.ALL})
private Set<UzytkownikZalogowanyInfo> userLogedInfo;

public Uzytkownik()
{
}


public Uzytkownik(String login, String haslo, String hash, String imie, String nazwisko, String mail, String telefon) {
super();
this.login = login;
this.haslo = haslo;
this.hash = hash;
this.imie = imie;
this.nazwisko = nazwisko;
this.mail = mail;
this.telefon = telefon;
}

Second

package pl.dbg.prawnicy.shared;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;

@Entity
@Table(name = "UzytkownikZalogowanyInfo")
@SuppressWarnings("serial")
public class UzytkownikZalogowanyInfo
{

@Id
@GeneratedValue
@Column(name = "userInfoId")
private Integer userInfoId;

@Column(name = "Zalogowany")
private Date zalogowany;

@Column(name = "Wylogowany")
private Date wylogowany;

@ManyToOne
@JoinColumn(name = "userId")
private Uzytkownik user;

public UzytkownikZalogowanyInfo()
{
}

public UzytkownikZalogowanyInfo(Date zalogowany, Date wylogowany, Uzytkownik user)
{
super();
this.zalogowany = zalogowany;
this.wylogowany = wylogowany;
this.user = user;
}

And this is my servlet code

@SuppressWarnings("serial")
public class GreetingServiceImpl extends RemoteServiceServlet implements GreetingService
{

public Uzytkownik greetServer() throws IllegalArgumentException
{
Session session = SessionManager.getSessionFactory().openSession();
Uzytkownik uzytkownik = null;

try {
session.beginTransaction();

List<Uzytkownik> uzytkownicyList = session.createCriteria(Uzytkownik.class).list();

if (!uzytkownicyList.isEmpty())
{
uzytkownik = uzytkownicyList.iterator().next();
System.out.println("Jest uzytkownik");

HibernateBeanReplicator replicator = new Hibernate3BeanReplicator("pl.dbg.prawnicy.shared");
replicator.initSetterMethodCollector(new PrivateSetterMethodCollector());
//HibernateBeanReplicator replicator = new Hibernate3BeanReplicator().initReaderMethodFinder(new PrivateReaderMethodFinder());
uzytkownik = uzytkownicyList.iterator().next();
Uzytkownik uzytkownikDTO = replicator.copy(uzytkownik);

UzytkownikZalogowanyInfo uzytkownikZalogowanyInfoDTO = replicator.copy(uzytkownikDTO.getUserLogedInfos().iterator().next());


uzytkownikDTO.getUserLogedInfos().clear();
uzytkownikDTO.getUserLogedInfos().add(uzytkownikZalogowanyInfoDTO);

System.out.println("Data z drugiego obiektu "+uzytkownikDTO.getUserLogedInfos().iterator().next().getWylogowany());
return uzytkownikDTO;
}

session.getTransaction().commit();

} catch (Exception e) {
e.printStackTrace();

} finally {
session.close();
}
return null;
}

}

I have tried every configuration from http://beanlib.svn.sourceforge.net/viewvc/beanlib/trunk/beanlib-doc/hibernate-bean-replicator.html

pleas help :D

Hi Przemek,

Any stack trace you can provide ?

anh I also post Screen with my libraries and a part of error

[Hanson Char]

The stack trace doesn't seem to have anything to do with Beanlib (or Hibernate).  This means the failure occur outside of beanlib.

Yes I know that this is GWT error, cause of different serialization

Problem is propably, in bad initialization Object that is copied.

Can You tell me is everything all right with this code in servlet ?

session.beginTransaction();

List<Uzytkownik> uzytkownicyList = session.createCriteria(Uzytkownik.class).list();

if (!uzytkownicyList.isEmpty())

{

uzytkownik = uzytkownicyList.iterator().next();

System.out.println("Jest uzytkownik");

HibernateBeanReplicator replicator = new Hibernate3BeanReplicator("pl.dbg.prawnicy.shared");

replicator.initSetterMethodCollector(new PrivateSetterMethodCollector());

//HibernateBeanReplicator replicator = new Hibernate3BeanReplicator().initReaderMethodFinder(new PrivateReaderMethodFinder());

uzytkownik = uzytkownicyList.iterator().next();

Uzytkownik uzytkownikDTO = replicator.copy(uzytkownik);

UzytkownikZalogowanyInfo uzytkownikZalogowanyInfoDTO = replicator.copy(uzytkownikDTO.getUserLogedInfos().iterator().next());

uzytkownikDTO.getUserLogedInfos().clear();

uzytkownikDTO.getUserLogedInfos().add(uzytkownikZalogowanyInfoDTO);

System.out.println("Data z drugiego obiektu "+uzytkownikDTO.getUserLogedInfos().iterator().next().getWylogowany());

 return uzytkownikDTO;

I would like to use it as DTO Object but without creating new DTO classes, just copy to new Object ?? how can I achive it ?
