Stereotype «PersistenceUnit»
Java Persistence API (JPA) defines so called persistence units. They are used to put a bunch of persistence objects together. All persistent classes within the same persistence unit share the same database connection and transaction.
Stereotype «PersistenceUnit» can be used to define a persistence unit. Therefore the persistence unit has to reference the packages from which the unit should be build up. JEAF Components that want to make use of classes of a persistence unit need to define a dependency on it.
