Creating a Hibernate Test Project using maven.

when i run the project, it generates Exception:

org.hibernate.engine.jdbc.connections.internal.ConnectionProviderInitiator initiateService WARN: HHH000181: No appropriate connection provider encountered, assuming application will be supplying connections org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set at org.hibernate.engine.jdbc.dialect.internal.DialectFactoryImpl.determineDialect(DialectFactoryImpl.java:104) at org.hibernate.engine.jdbc.dialect.internal.DialectFactoryImpl.buildDialect(DialectFactoryImpl.java:71) at org.hibernate.engine.jdbc.internal.JdbcServicesImpl.configure(JdbcServicesImpl.java:209) at org.hibernate.boot.registry.internal.StandardServiceRegistryImpl.configureService(StandardServiceRegistryImpl.java:89) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:206) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:178) at org.hibernate.cfg.Configuration.buildTypeRegistrations(Configuration.java:1885) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1843) at org.hibernate.hibernatetest.App.main(App.java:33) Exception in thread "main" java.lang.NullPointerException at org.hibernate.hibernatetest.App.main(App.java:51)

But in main class required properties are set.don't know why programme is genrAating exception.

Main Class:

public class App { public static void main(String[] args) { Configuration configuration; ServiceRegistry serviceRegistry; SessionFactory sessionFactory; Session session = null; try { configuration = new Configuration(); serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build(); configuration.setProperty("hibernate.dialect ", "com.applerao.hibernatesqlite.dialect.SQLiteDialect"); configuration.setProperty("hibernate.connection.url ", "jdbc:sqlite:TailorDB.db"); configuration.setProperty("hibernate.connection.driver_class ", "org.sqlite.JDBC"); configuration.setProperty("hibernate.connection.username ", ""); configuration.setProperty("hibernate.connection.password ", ""); sessionFactory = configuration.buildSessionFactory(serviceRegistry); session = sessionFactory.openSession(); CustomerModel c = new CustomerModel(); c.setID(5); c.setNIC_Number("691201631345"); c.setFirstName("Zee"); c.setNumber("55225522"); c.setLastName("Jan"); c.setCustomerCode("Zee-123"); session.beginTransaction(); session.save(c); session.getTransaction().commit(); } catch (HibernateException e) { e.printStackTrace(); } finally { session.close(); } } }

In POM file:

<dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.0.Final</version> </dependency> <dependency> <groupId>org.xerial</groupId> <artifactId>sqlite-jdbc</artifactId> <version>3.7.2</version> </dependency> <dependency> <groupId>com.applerao</groupId> <artifactId>hibernatesqlite</artifactId> <version>1.0</version> </dependency> </dependencies>

Any idea where the problem can be??

CustomerModel cLass:

@Entity @Table(name = "Customer") public class CustomerModel { @Id @GeneratedValue @Column(name = "c_id") int ID; @Column(name = "c_code") String customerCode; @Column(name = "c_fname") String firstName; @Column(name = "c_mname") String middleName; @Column(name = "c_lname") String lastName; @Column(name = "c_nic") String NIC_Number; @Column(name = "c_email") String email; @Column(name = "c_pnumber") String number; }

How do you resolve access to DialectResolutionInfo Cannot be null when Hibernate Dialect not set?

Fix for HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate. dialect' not set. After some research and debugging, I was able to fix it. The part that is missing in the official documentation is that we need to apply the configuration properties to StandardServiceRegistryBuilder .
