Error message:An AnnotationConfiguration instance....

Hallo,
I hope you can help me.
I always get the error message: An AnnotationConfiguration instance is required to use <mapping package="contacts"/>

Hibernate version:
Hibernate3rc1
Hibernate Annotations 3.0 alpha 3

Mapping documents:hibernate.cfg.xml

Code:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "C:/Uni/SS_05/Programmierpraktikum/workspace/hibernating/lib/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
   <session-factory>
   
      <!-- properties -->
      
      <property name="hibernate.connection.driver_class">
         com.mysql.jdbc.Driver
      </property>
      <property name ="hibernate.connection.url">
         jdbc:mysql://127.0.0.1/praktikum
      </property>
      <property name ="hibernate.connection.username">root</property>
      <property name ="hibernate.dialect">
         org.hibernate.dialect.MySQLDialect
      </property>      
      <property name="hibernate.connection.pool_site">
         4
      </property>
      <property name ="hibernate.show_sql">

      <!-- mapping files -->
      <mapping package="contacts"/>
      <mapping class="contacts.ContactInfo"/>
      
   </session-factory>
</hibernate-configuration> 

Code between sessionFactory.openSession() and session.close():

Code:

public static void main(String[] args) throws HibernateException,
         SQLException {
        
      Configuration config = new Configuration();
      config.configure();

      // update database schema if required
      new SchemaUpdate(config).execute(true, true);

      //create session
      Session session = HibernateUtil.currentSession();

      //examples of using database with Contacts
      //examplesContact(session);

      //exapmles of using database with Folders
      examplesFolder(session);

      // close Session
      HibernateUtil.closeSession();
      System.exit(0);
   }

And thats class HibernateUtil

Code:

package main;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateUtil {

    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory
            sessionFactory = new AnnotationConfiguration().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static final ThreadLocal session = new ThreadLocal();

    public static Session currentSession() throws HibernateException {
        Session s = (Session) session.get();
        // Open a new Session, if this Thread has none yet
        if (s == null) {
            s = sessionFactory.openSession();
            session.set(s);
        }
        return s;
    }

    public static void closeSession() throws HibernateException {
        Session s = (Session) session.get();
        session.set(null);
        if (s != null)
            s.close();
    }
}

why dont you read the stacktrace ? ;)

you are instantiating a Configuration and the stacktrace clearly states you need to instnatiate a AnnotationConfiguration.

Well.... , okay,...that's right, and I already changed that, and I'm getting an new Error Message:
NoSuchMethodError:
org.hibernate.mapping.PersistentClass.setDynamic(Z)V[b]
And this message is really weired, because I looked at the source code of PersistentClass, and this method really doesn't exist. Only setDynamixInsert and setDynamicUpdate exists (I'm not sure with the names).

[b]Code between sessionFactory.openSession() and session.close():

Code:

public static void main(String[] args) throws HibernateException, 
         SQLException { 
      //create session 
      Session session = HibernateUtil.currentSession(); 

      //examples of using database with Contacts 
      //examplesContact(session); 

      //exapmles of using database with Folders 
      //examplesFolder(session); 

      // close Session 
      HibernateUtil.closeSession(); 
      System.exit(0); 
   }

And thats class HibernateUtil
public class HibernateUtil {

private static final SessionFactory sessionFactory;
private static final AnnotationConfiguration cfg;

static {
try {
cfg = new AnnotationConfiguration();
cfg.configure();
new SchemaUpdate(cfg).execute(true, true);
sessionFactory = cfg.buildSessionFactory();

} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}

seems like annotations is using a method that is now removed in H3 RC.

you'll have to use a older version of hibernate 3 to work with annotations.

you could try the cvs version of annotations if you want ,)
