Hi! I am new in hibernate annotations so i am practising it on the console. In here i am using hibernate3.jar(came with Hibernate 3.5.1), hibernate-annotations-3.4.0.GA.jar etc.
However when i run the main the application didn't start and following errors were generated.
Any idea,please help.. !??

Try to use this HibernateUtil

public class HibernateUtil {

    private static final SessionFactory SESSION_FACTORY = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            return new AnnotationConfiguration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            throw new ExceptionInInitializerError(ex);
        }
    }

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

PETER ,
Sorry for being late! I 've been working on it with your new HibernateUtil class however the folllowing errors troubles me deeply..
Peter any other idea??

Thank you Peter ! I nearly start a survey on Maven to find my lost jars..
Anyway thanks again, Daniweb numberone !

There been some changes with Hibernate 3.5 and 3.6 so in many cases following many online tutorials will get you in trouble. My quick take on the problem:

  • With 3.5 and higher there is no more need for hibernate-annotations dependency as this is now packages as part of hibernate-core (check Hibernate documentation for setup and configuration)
  • With 3.6 AnnotationConfiguration is deprecate and you need to replace it with Configuration
    So previously used HibernateUtil class looking like
    import org.hibernate.SessionFactory;
    import org.hibernate.cfg.AnnotationConfiguration;
    
    public class HibernateUtil {
    
        private static final SessionFactory SESSION_FACTORY = buildSessionFactory();
    
        private static SessionFactory buildSessionFactory() {
            try {
                return new AnnotationConfiguration().configure().buildSessionFactory();
            } catch (Throwable ex) {
                throw new ExceptionInInitializerError(ex);
            }
        }
    
        public static SessionFactory getSessionFactory() {
            return SESSION_FACTORY;
        }
    }

    now looks as

    import org.hibernate.SessionFactory;
    import org.hibernate.cfg.Configuration;
    
    public class HibernateUtil {
    
        private static final SessionFactory SESSION_FACTORY = buildSessionFactory();
    
        private static SessionFactory buildSessionFactory() {
            try {
                return new Configuration().configure().buildSessionFactory();
            } catch (Throwable ex) {
                throw new ExceptionInInitializerError(ex);
            }
        }
    
        public static SessionFactory getSessionFactory() {
            return SESSION_FACTORY;
        }
    }
  • In case of following error
    java.lang.NoClassDefFoundError: org/hibernate/annotations/common/reflection/MetadataProvider

    make sure that you are not using

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-commons-annotations</artifactId>
        <version>3.3.0.ga</version>
    </dependency>

    that is reported as release by mistake with some bugs, but rather use

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-commons-annotations</artifactId>
        <version>3.2.0.Final</version>
    </dependency>
