Starting a Java Persistence project The Hibernate configuration file previously had a list of all XML mapping files. This has been replaced with a list of all annotated classes. If you use programmatic configuration of a SessionFactory, the addAnnotatedClass() method replaces the addResource() method: // Load settings from hibernate.properties AnnotationConfiguration cfg = new AnnotationConfiguration(); // … set other configuration options programmatically cfg.addAnnotatedClass(hello.Message.class); SessionFactory sessionFactory = cfg.buildSessionFactory(); Note that you have now used AnnotationConfiguration instead of the basic Hibernate Configuration interface this extension understands annotated classes. At a minimum, you also need to change your initializer in HibernateUtil to use that interface. If you export the database schema with an Ant target, replace with in your build.xml file. This is all you need to change to run the Hello World application with annotations. Try running it again, probably with a fresh database. Annotation metadata can also be global, although you don t need this for the Hello World application. Global annotation metadata is placed in a file named package-info.java in a particular package directory. In addition to listing annotated classes, you need to add the packages that contain global metadata to your configuration. For example, in a Hibernate XML configuration file, you need to add the following: Or you could achieve the same results with programmatic configuration:
