hibernate.cfg.xml not found (The file actually doesn't exist). Configuration is in dispatcher-servlet

Question

I have configured hibernate in my dispatcher servlet. The program starts fine. But when creating a Configuration object and configuring it by calling the configure() method, the error is thrown:

    Apr 03, 2013 9:14:58 PM org.hibernate.cfg.Configuration configure

How can I get the Configuration object to configure from the dispatcher servlet where the hibernate configuration is defined?

The method that builds the sessionfactory is as follows:

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

static {
    try {
        //Configuration configuration = new Configuration();
        Configuration configuration = new Configuration().configure();

        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    }
    catch(HibernateException he) {
        System.err.println("Error creating session: " + he); 
        throw new ExceptionInInitializerError(he);
    }
}

The dispatcher-servlet code is as follows:

Answer 1

Through you have integrated hibernate to spring why do you still use hibernate to build sessionFactory, in other words, you don't have to use hibernate.cfg.xml there is a sessionFactory bean already in the applicationContext.xml, just use annotation to get it's instance. then enjoy it:)

see your another question for my answer SessionFactory injection isn't working

Good luck!

Answer 2

root cause is org.hibernate.HibernateException: /hibernate.cfg.xml not found. By default Hibernate configuration manager try to find cfg file in WEB-INF/classes, put your hibernate.cfg.xml in WEB-INF/classes foldern and it should work.

Edit::

You are trying to buid session factory by own hence it is just like typical hibernate application. In this case hibernate.cfg.xml will be required. But you can see there is session factory bean in application-contex.xml. When spring loads the xml then hibernate.cfg.xml is not requıred because session factory is already defined in application-context and it will be created.

Answer 3

Yes you are right. why you need configuration file if you are providing it in dispatcher.

but your accessing session factory is wrong.

"Configuration configuration = new Configuration().configure();" will always go for

Configuration file. You need to access it by HibernateTamplate which is provided by Spring.
