> For any example that is deploying to a standard Java EE 5 environment (for instance the jpa example deploying to GlassFish or JBoss AS 5), the entity manager factory should be obtained through JNDI through a persistence unit reference.
> 5.3.1 of JPA spec:
> "Within a Java EE environment, an entity manager factory may be injected using the Persistence-Unit annotation or obtained through JNDI lookup."
> It would first need to be declared in web.xml:
>    <persistence-unit-ref>
>       <persistence-unit-ref-name>bookingDatabase/emf</persistence-unit-ref-name>
>       <persistence-unit-name>bookingDatabase</persistence-unit-name>
>    </persistence-unit-ref>
> Then the components.xml would look like this:
> <persistence:managed-persistence-context name="entityManager"
>     auto-create="true"
>     persistence-unit-jndi-name="java:comp/env/bookingDatabase/emf" />
> The reason we should do this is to advocate the Java EE standard approach.
