Package hibernate3-annotations: Information

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). In
Hibernate 2.x, mapping metadata is most of the time declared
in XML text files. Another option is XDoclet, utilizing
Javadoc source code annotations and a preprocessor at compile
time.
The same kind of annotation support is now available in the
standard JDK, although more powerful and better supported by
tools. IntelliJ IDEA, for example, supports auto-completion
and syntax highlighting of JDK 5.0 annotations. The EJB3
specification standardizes the basic APIs and the metadata
(using JDK 5.0 annotations) needed for any object/relational
persistence mechanism. Hibernate EntityManager for EJB3
implements the programming interfaces and lifecycle rules as
defined by the EJB3 persistence specification. Both Hibernate
EntityManager and Hibernate Annotations are available in
standalone preview releases, however, they require Hibernate
3.1 and JDK 5.0. If you are not using EJB3 persistence,
please continue using Hibernate 3.0.x (with any JDK supported).
The Hibernate Annotations package provides annotations for
Standard JSR-220 defined O/R mapping
Hibernate O/R mapping extensions
Data validation via the Hibernate Validator framework
