Hibernate - Initial SessionFactory creation failed.org.hibernate.MappingNotFoundExcep

[Beacons]

Ciao, qualcuno di voi mi saprebbe dire questa eccezione da cos'è causata?

A quanto ho capito nel file hibernate.hbm.xml non sarebbe mappata la classe:

<hibernate-mapping>
  <class name="Utenti" table="utenti"/>
</hibernate-mapping> 

Utenti sarebbe l'oggetto hibernate e utenti la tabella.

[antotan]

hai creato il file xml di mapping della classe Utenti?

edit: dal codice che hai postato presumo di sì. Hai indicato il file di mapping nel file di configurazione? Qualcosa del genere (adattalo al tuo file xml di mapping):

[php]
<session-factory>
.
.
.
<mapping resource="hibernate.hbm.xml"/>
.
.
.
</session-factory>
[/php

[Beacons]

il problema che già c'è. Nell'hibernate.cfg.xml è già mappato hibernate.hbm.xml...

[antotan]

Dove sono collocati i file?

I file di hibernate hanno una struttura simile a questa?

hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
    <property name="hibernate.connection.username">user</property>
    <property name="hibernate.connection.password">pass</property>
    <property name="current_session_context_class">thread</property>
    <mapping class="" file="hibernate.hbm.xml" jar="" package="" resource="hibernate.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

hibernate.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="data.Person" table="Person">
        <id name="id" column="id">
            <generator class="native"/>
        </id>

        <property name="firstname" type="text" column="firstname"/>
        <property name="lastname" type="text" column="lastname"/>
    </class>
</hibernate-mapping>

[Beacons]

yes... guarda ti posto tutto il codice:

hibernate.hbm.xml:

<hibernate-mapping>
  <class name="Utenti" table="utenti"/>
</hibernate-mapping> 

hibernate.revenge.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">
<hibernate-reverse-engineering>
  <schema-selection match-catalog="mioDB"/>
  <table-filter match-name="utenti"/>
</hibernate-reverse-engineering>

hibernate.cfg.xml:

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mioDB</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">root</property>
    <mapping resource="hibernate/Utenti.hbm.xml"/>
    <mapping resource="hibernate/hibernate.hbm.xml"/>
  </session-factory>
</hibernate-configuration> 

ovviamente utenti.hbm.xml è l'oggetto che rappresenta la tabella utenti. Al livello di codice ho semplicemente fatto una query :


mi sono fatto un UtentiHome:

package dao;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class UtentiHome {
    private static final SessionFactory sessionFactory;

    static {
        try {
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
} 

e un UtentiBusiness:

public class UtentiBusiness extends UtentiHome{

    public static List<Utenti> listaUtenti() throws IllegalStateException, SystemException, RollbackException, HeuristicMixedException, HeuristicRollbackException{
        List<Utenti> elenco = null;
        Session session = UtentiHome.getSessionFactory().openSession();

        try {
            org.hibernate.Transaction tx = session.beginTransaction();
            Query q = session.createQuery("from utenti");
            elenco = q.list();
            tx.commit();
        }
        catch(RuntimeException error){
            error.printStackTrace();
        }
        return elenco;
    }
} 

l'eccezione che ora mi da è la seguente:

java.lang.NoClassDefFoundError: Could not initialize class business.UtentiBusiness

che poi mica istanzio UtentiBusiness visto che il metodo è dichiarato statico.


anzi questa era una vecchia eccezione, la nuova è:

Hai il file hibernate.hbm.xml dove mappi la classe Utenti (appartenente al package default).

Nel file di configurazione vedo questa linea:

<mapping resource="hibernate/Utenti.hbm.xml"/>

hai un file xml del genere?

Puoi postare il codice di Utenti.java e Utenti.hbm.xml? Sicuro che Utenti non appartenga al package dao?

[Beacons]

Utenti.hbm.xml è praticamente il file xml che rappresenta la tabella utenti

<hibernate-mapping>
    <class name="hibernate.Utenti" table="utenti" catalog="nift">
        <id name="idUtente" type="java.lang.Integer">
            <column name="idUtente" />
            <generator class="identity" />
        </id>
        <property name="nickname" type="string">
            <column name="nickname" not-null="true" />
        </property>
        <property name="password" type="string">
            <column name="password" not-null="true" />
        </property>
        <property name="nome" type="string">
            <column name="nome" />
        </property>
        <property name="cognome" type="string">
            <column name="cognome" />
        </property>
        <property name="email" type="string">
            <column name="email" />
        </property>
    </class>
</hibernate-mapping> 

Utenti è sempre un oggetto rappresentante la tabella utenti

public class Utenti  implements java.io.Serializable {


     private Integer idUtente;
     private String nickname;
     private String password;
     private String nome;
     private String cognome;
     private String email;

    public Utenti() {
    }

    
    public Utenti(String nickname, String password, Date dataDiNascita) {
        this.nickname = nickname;
        this.password = password;
        this.dataDiNascita = dataDiNascita;
    }
    public Utenti(String nickname, String password, String nome, String cognome, String email) {
       this.nickname = nickname;
       this.password = password;
       this.nome = nome;
       this.cognome = cognome;
       this.email = email;


//con i relativi metodi getter e setter 

[antotan]

Per ora non ci vedo niente di strano.
Ma hibernate.hbm.xml a che ti serve se mappi Utenti in un file xml a parte?

[Beacons]

ok tolta...e in hibernate.cfg ho mappato soltanto utenti. ora l'eccezione è:

ma io utenti l'ho mappataO_O

[antotan]

L'HQL dovrebbe prevedere il nome della classe non la tabella. Prova

Query q = session.createQuery("from hibernate.Utenti");

dovrebbe andare anche senza specificare il package comunque.
