How to use EJB-CMT with Spring and JSF in STS? - spring

Question

Is it possible? I want to use it like described here:
#PersistenceContext
private EntityManager em;
...
em.persist( entity1 );
em.merge( entity2 );
em.find( MyEntity.class, id );
(Still working on this project)
I successfully tried to get a database connection with this persistence unit:
<persistence-unit name="primefaces-showcase"
transaction-type="RESOURCE_LOCAL">
<class>org.primefaces.showcase.domain.Car</class>
<properties>
<property name="javax.persistence.schema-generation.database.action"
value="drop-and-create" />
<property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/database" />
<property name="javax.persistence.jdbc.user" value="postgres" />
<property name="javax.persistence.jdbc.password" value="pass" />
<property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
<property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
</properties>
</persistence-unit>
I used it like this
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("primefaces-showcase");
EntityManager em = emf.createEntityManager();
But when I want to use JNDI like this
#PersistenceContext(unitName = "primefaces-jta")
private EntityManager em;
I get this console output:

Answer 1

I think the answer is that it is not possible to get CMT with the vFabric tc server this way, as it doesn't offer a transaction manager out of the box. So I'm going to look how to use the Spring framework to solve this problem.
