Multiple JPA database instances

[josete]

Hi everyone !

I'm facing a problem on trying to get Tapestry 5.3.7 to use multiple JPA
database for same application.

I do have an administration console with a big options menu.

In order to speedup some of the functionality, i defined an extra database
that will be queried against.

My problem lies in that looks like 2 EntityManagers can't manage the same
entities.

I've check tapestry-jpa src-code, and the problem? lies in here :

Class JPAModule.java
<pre>
   @Contribute(ApplicationStateManager.class)
    public static void provideApplicationStateContributions(
            final MappedConfiguration<Class, ApplicationStateContribution>
configuration,
            final EntityManagerSource entityManagerSource,

@Symbol(JpaSymbols.ENTITY_SESSION_STATE_PERSISTENCE_STRATEGY_ENABLED)
            final boolean entitySessionStatePersistenceStrategyEnabled)
    {


 if (!entitySessionStatePersistenceStrategyEnabled)
            return;

        for (final PersistenceUnitInfo info :
entityManagerSource.getPersistenceUnitInfos())
        {
            final EntityManagerFactory emf =
entityManagerSource.getEntityManagerFactory(info.getPersistenceUnitName());

            final Metamodel metamodel = emf.getMetamodel();

            for (EntityType<?> entity : metamodel.getEntities())
            {
                configuration.add(entity.getJavaType(), new
ApplicationStateContribution(JpaPersistenceConstants.ENTITY));
            }

        }
}
</pre>

As you can see, for every entity, tapestry is adding the entity type to the
share configuration.
As Entity X is already managed by configuration for Database1, when same
Entity X from Database2 is added to the configuration, it just throws an
Exception.

How can i fix this ?

I do REALLY need the same instance managed by both instances.

Thanks a lot.
