The Enterprise JavaBeans (EJB) 3.0 specification includes an additional persistence specification called the Java Persistence API (JPA). It is an API for creating, removing and querying across lightweight Java objects and can be used both within a compliant EJB 3.0 Container and a standard Java SE 5 environment. TopLink Essentials is the open-source community edition of Oracle's TopLink product. It provides the JPA functionality for the EJB 3.0 Reference Implementation. It should be noted that toplink-essentuals is an essentual (get it ;) ) part of the glassfish-persistence API. It is the engine for our glassfish-persistence package. The ebuild is avilable in the java-experimental overlay for now.
This is not needed anymore (signed off on by fordfrog). Let's move on.
