Hibernate 4 Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

Question

I am using Hibernate latest version 4.3.5.Final.

My hibernate.cfg.xml file content:

Answer 1

Finally able to fix the issue, the issue is with the way SessionFactory is getting created.

For a starter, official document is the first place to go and I must say that Hibernate official documentation seems to be not update with latest version changes.

Fix is to apply the configuration settings to StandardServiceRegistryBuilder instance.

// Create the SessionFactory from hibernate.cfg.xml
Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
        .applySettings(configuration.getProperties()).build();
SessionFactory sessionFactory = configuration
        .buildSessionFactory(serviceRegistry);

Please refer my blog post here for more details.

Answer 2

In my case I ran the configuration routine twice. I had automatic configuration (ie config from xml in resources) in one method, then I implemented a configuration by setting properties in another method but I forgot to bypass the former. As soon as I did, the error gone.

Answer 3

You cal also fix the issue by creating the sesisonFactory this way.

SessionFactory sessionFactory = new
Configuration().configure().buildSessionFactory(
new StandardServiceRegistryBuilder().applySettings(new
Configuration().configure().getProperties()).build());

Answer 4

I had the exactly the same problem and the issue was, that my computer was not entered in the pg_hba.conf of the postgres database that allows which Clients(IP-Adresses) are allowed to speak with the database

Answer 5

The same problem occurred to me with the mysql service running, correct credentials, but the database name was misspelled, so basically the database did not exist.

Answer 6

This will be OK

Configuration cfg = new Configuration().configure();

StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
        .applySettings(cfg.getProperties()).build();

SessionFactory sf = cfg.buildSessionFactory(serviceRegistry);

Session session = sf.openSession();
