Hi.
I'm using JBoss-4.0.4RC1 with EJB-3.0_RC4-PFD.
It is not possible to get an EntityManagerFactory via JNDI lookup!
Here is the code inside my session bean:
// Create entity manager via entity manager factory
| EntityManagerFactory emf =
(EntityManagerFactory)getSessionContext().lookup("java:/EntityManagerFactory/"
+ unitName);
| EntityManager entityManager = emf.createEntityManager();
(I prefer this way, to get an EntityManager, to have the ability to define an
extended EntityManager for SFSBs.)
That's the corresponding persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
|
| <entity-manager>
| <!-- Entity Manager definition -->
| <persistence-unit name="LibraryDB1" transaction-type="JTA">
| <!-- Entity classes -->
| <jar-file>../library.jar</jar-file>
| <!-- Data source name -->
| <jta-data-source>java:/LibraryDB1</jta-data-source>
|
| <properties>
| <!-- JNDI entry to get the Entity Manager Factory via
lookup -->
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/EntityManagerFactory" />
|
| <property name="hibernate.dialect"
value="org.hibernate.dialect.PostgreSQLDialect" />
| <property name="hibernate.hbm2ddl.auto" value="update"
/>
| </properties>
| </persistence-unit>
| </entity-manager>
That's the logging of JBoss when deploying my JAR files (consider the
red-colored line):

BTW: It is possible to get an EntityManager via injection:
@PersistenceContext(unitName="LibraryDB1") private EntityManager entityManager;
But that's not suitable for my application which must be able to dynamically
create databases!
Any ideas?
