Hibernate 3.6: Schema Export schlägt fehl, autocommit = false?

Question

Im Hibernate Buch über Schema Export lesen: http://jpa.ezhibernate.com/Javacode/learn.jsp?tutorial=02validatingthehibernateenvironment

Ich habe versucht, den Code in Hibernate 3.6, aber das Schema wird nicht erstellt, ausgeführt wird, und aus dem Ausgabeprotokoll unter der Annahme, vielleicht ist es nicht irgendwie verpflichtet. Hier ist die Log-Ausgabe:

105 [main] INFO org.hibernate.annotations.common.Version - Hibernate Commons Annotations 3.2.0.Final 
118 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.6.0.Final

347 [main] INFO org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:postgresql://localhost:5432/hibernate 

Hier ist mein Code:

import javax.persistence.GeneratedValue; 
import javax.persistence.Id; 

import org.hibernate.cfg.AnnotationConfiguration; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.tool.hbm2ddl.SchemaExport; 


public class User { 
    private Long id; 
    private String name; 

    @Id 
    @GeneratedValue 
    public Long getId() { 
     return id; 
    } 

    public void setId(Long id) { 
     this.id = id; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    /** 
    * @param args 
    */ 
    public static void main(String[] args) { 
     Configuration config = new Configuration(); 
     config.addAnnotatedClass(User.class); 
     config.configure(); 
     new SchemaExport(config).create(true, true); 
    } 
} 

und hier ist meine Hibernate cfg xml:

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

    <!-- MOHON DITAMBAHKAN SESUAI PACKAGE DAN URUT ABJAD --> 

    <session-factory> 
     <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property> 
     <property name="connection.driver_class">org.postgresql.Driver</property> 
     <property name="connection.username">sofco</property> 
     <property name="connection.password">kamalbert</property> 
     <property name="connection.url">jdbc:postgresql://localhost:5432/hibernate</property> 
     <property name="show_sql">true</property> 
     <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> 
     <property name="current_session_context_class">thread</property> 
    </session-factory> 

</hibernate-configuration> 

Ich frage mich, was ich hier fehlt ..

Es scheint, dass einige Dinge in den Protokollen fehlen, aber es ist wahrscheinlich, weil Sie Ihre Entität nicht mit @Entity markiert haben.
