Managed persistence context

[chris.simons]

Can anyone familiar with EJB3 and interoperability with non-JBoss application servers explain the difference between these two components.xml scenarios?

Scenario 1

<persistence:managed-persistence-context name="entityManager"
               auto-create="true"
               persistence-unit-jndi-name="/comp/env/#{project.name}/entityManagerFactory"/>


    <transaction:entity-transaction entity-manager="#{entityManager}"/>

Scenario 2

<transaction:ejb-transaction/>

In addition, can you inject EntityManager, such as in:

@In
private EntityManager entityManager

...when using Scenario 2?

For sure you can inject EntityManager in both scenarios. As to first part...hm...I have never used entity-transaction.

[chris.simons]

The Seam JEE5 examples use <transaction:ejb-transaction/> and in those examples, they inject EntityManager using @PersistenceContext.

So I'm trying to wrap my head around the difference here.

Thanks.
