Jndi name of persistence unit (persistence.xml)

[kudlaty15]

I am using Jboss EJB3/JPA integration to get Hibernate SessionFactory object defined in persistence.xml. I am able to inject SessionFactory to EJB by annotation @PersistenceUnit. But I have to use SessionFactory in one servlet. Here the problems begin. Injection to servlet not working and I cannot use spring injection becouse of the application architecture. Then in jboss logs I saw that automatically server bind SessionFactory described in persistence.xml to JNDI. So I can get SessionFactory object by InitialContext.lookup() and it's work. The problem is in name of the JNDI. Jboss automatically assign unacceptable and ugly name like: INFO [SessionFactoryObjectFactory] Bound factory to JNDI name: persistence.unit:unitName=my_application.ear/my_application-service-1.1.2-JBOSS-SNAPSHOT.jar#hibernateUnitMyApplication. The name is very long and contains for example name and versions of jar and more unnecessary information. The question is HOW I CAN CHANGE THIS NAME? I know that I can use properties like: <property name="jboss.entity.manager.jndi.name" value="java:/Manager1"/> or <property name="jboss.entity.manager.factory.jndi.name" value="java:/Manager1Factory"/> in persistence.xml file to create global JNDI of my persistence unit. This solution is not satisfactory becouse the InitialContext.lookup returns EntityManager object while I want SessionFactory:( Please help:)

On this website You can read about cool Jboss EJB/JPA integration - http://bill.burkecentral.com/2007/07/06/co-existence-with-hibernate-jpa-and-ejb3

Correction - I have to use SessionFactory object in POJO:) That POJO class use servlet so getting SessionFactory can be "done at two levels" - servlet or pojo.

Jboss AS 5.1

hope this will help

I know that my post is a liitle to long, but please read carefully. I know that I can create global JNDI of my persistence unit by some properties in persistence.xml! Lookup on this jndi will return EntityManager or EntityManagerFactory(depends on property). I am using Hibernate and I must get SessionFactory (Hibernate). This cool integration :http://bill.burkecentral.com/2007/07/06/co-existence-with-hibernate-jpa-and-ejb3 can mix hibernate with jpa and ejb3 from JBOSS. This is very cool feature becouse Jboss create for U SessionFactory object and U can inject this object with nice annotation (@PersistenceUnit). Later I was trying Hibernate MBean in JBoss but this solution is not universal and it's slowly departs (for example there is a couple important properties that is not mapped to Jboss MBean Hibernate service). My question was about naming convention in Jboss.  Server automatically bind SessionFactory described in persistence.xml but the name of jndi is unacceptable. Can i change name of this jndi ?

You can do this:

EntityManager em = (EntityManager) initialCtx.lookup("java:/Manager1");
SessionFactory sessionFactory = em.unwrap(Session.class).getSessionFactory();

where Session and SessionFactory are from the appropriate Hibernate package.
