How to share Entity classes across multiple Persistence Unit?
I have 2 MySql databases (dbOne, dbTWO) with the same table "users"
I would like to have an Entity class like this :
#Entity
public class User {
...
...
}
shared between the 2 PU (of dbONE and dbTWO).. (eclipse.persistence)
i tried with :
<persistence-unit name="one_PU" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>com.model.User</class>

without success..
Is it possible?..how can i do that?
I have a very minimal test that properly configures openJPA, JTA, database connectivity, enhancement and emits no exceptions however it does not persist with the simple code below. What more do I need to show or what is necessary beyond the simple statements to actually write records to the db?
public class Manipulation00 {
public Manipulation00(){}
public void startUp(ServletContext sc){
EntityManagerFactory emf =
(EntityManagerFactory)sc.getAttribute("emf");
EntityManager em = emf.createEntityManager();
Exemptions00 exempt00 = new Exemptions00();
exempt00.setUpc("722430001166");
exempt00.setDesc("KOMBUCHA,OG2,SEASONAL");
em.persist(exempt00);
}
}

I'd guess that your transaction isn't being committed.

I use EJB to insert/update data to the database and I have this problem. My commit only works with updating(merge), but doesn't rollback inserts(persist). Even more, my inserts(persist) happen before transaction commit.
my persistence unit:

how i inject entity manager factory
#PersistenceUnit(unitName="bpmBeans_RESOURCE_LOCAL")
public EntityManagerFactory emf;
what happens with the code
EntityManager em = emf.createEntityManager();
EntityTransaction ets = em.getTransaction();
ets.begin();
Process newObj = new Process();
em.persist(newObj); //data gets inserted at this moment, not at commit
...
...
if(allgood){
ets.commit();// now update(merge, setters on managed entities) would happend.
} else {
ets.rollback(); // this would rollback the updates, but not the insert
}
Any ideas what to try? I guess I'm just understanding some JPA concepts badly.
