Hibernate, like all other object/relational mapping tools, requires metadata that governs the transformation of data from one representation to the other (and vice versa). As an option, you can now use JDK 5.0 annotations for object/relational mapping with Hibernate 3.2. You can use annotations in addition to or as a replacement of XML mapping metadata. . You can use Hibernate extension annotations on top of standardized Java Persistence annotations to utilize all native Hibernate features. . This package ships the Hibernate Commons Annotations classes used by annotations based Hibernate sub-projects.
