The Bean Validation specification went final around the same time that the Java EE 6 specifications went final. The Java Persistence 2.0 specification allows for Managed classes (entities, mapped superclasses and embeddable classes) to be configured with Bean Validation constraints.
Generating the JPA 2.0 Static MetaModel classes using Eclipselink 2.0 and Netbeans 6.8 for your Entity Classes
Eclipselink 2.0 includes an annotation processor for generating the static metamodel classes from your Entity classes for use with the Criteria API which is one of the new features in JPA 2.0.
Here is an example of generating the metamodel classes from the command line using the Eclipselink annotation processor:
One of the many cool new features in Java EE 6, is support for the DataSourceDefinition annotation.
The DataSourceDefinition annotation provides a way to define a DataSource and register it with JNDI. The annotation provided annotation elements for the commonly used DataSource properties. Additional standard and vendor specific properties may also be specified.
A gentle guide to getting started with OpenJDK and Mercurial on Solaris
This Connector is modeled after JDBC making it very easy to access MySQL using C++.
