Shows use of *@PersistenceContext* to have an *EntityManager* with an *EXTENDED* persistence context injected into a @Stateful bean. An EJB 3 *@Entity* bean is used with the EntityManager to create, persist and merge data to a database.
If you need to use a TRANSACTION persistence context, see [this example|Testing Transactions Example].
_The source for this example is in the "injection-of-entitymanager" directory located in the [openejb-examples.zip|OPENEJB:Download] available on the download page._
