[jboss-user] [JBoss Seam] - SMPC:@In EntityManager or @PersistenceContext ?

[dkane]

Dear colleagues, 

I've read a lot about advantages of SMPC in this forum. 
In documentation, the recommended way to configure and use SMPC is : 

components.xml : 
<core:managed-persistence-context name="bookingDatabase" 
  |                            auto-create="true"
  | persistence-unit-jndi-name="java:/EntityManagerFactories/bookingData"/>

Java code : 
@In EntityManager bookingDatabase;

The best way of learning is examples , and I am looking into Seam 2.0 examples directory then. 
Almost all examples contains the corresponding configuration tag in components.xml. 
However, entityManager is being injected with @PersistenceContext or 
@PersistenceContext(TYPE=EXTENDED) in the vast majority of Java code. The canonical examples Booking and DVDStore does that too. 

Is SMPC actually used in Seam examples ? If not (BTW, why ?), where can I see sources of complete SMPC application ? 

Thank you.
