If WB does check for @Entities and orm.xml it also needs to read the right
META-INF/persistence.xml or a representation of it because:
- classes might not be scanned
- some non annotated class can be explicitly listed

If we are OK to go the non standard route, I can look at adding a method on
HibernateEntityManagerFactory.
SetClass? getEntities();
returning the list of entities.
Or even better you can do
Collection metadatas = (Map) ( (HibernateEntityManagerFactory) emf
https://anonsvn.jboss.org/repos/hibernate/core/trunk/entitymanager/src/main/java/org/hibernate/ejb/packaging/PersistenceXmlLoader.java
is your best shot.
EnumerationURL xmls = Thread.currentThread()

So Carlo,
Are you asking for a *standard* way to get the list of entities. ie a
EntityManagerFactory.getEntities()
This is not be easy to get for a few reasons, one of them being that you
probably want to return some metadata model rather than the plain class and
that it would take time to do
I've been thinking about it a bit more.
Unfortunately, I don't think it should be the job of Hibernate to give that
info. Here is my reasoning:
- if an app uses 2 persistence providers (different), then you need to get the
entities from both and an app server I think is required to work well
Lucene is using an inverted index technology, not a b-tree nor bitmap
technology. It particularly shines at indexing text documents. It's probably
not the best technology to index FKs, though it can do it.
At this stage, I would encourage you to write a small proof of concept, that's
the only
Can you try to not give them the same name. If these are supposed to be the
same PU, why several files. If they are supposed to be different PU, why the
same name :)
Anyway I don't think it's related to your problem.
One way to work around it is to manually list the classes in persistence.xml
This forum should be read-only now. Test.

Let's move back this thread to the Hibernate Forum (the one you started
already). Long story short, your analysis is correct except that
Search.createFTEM will not return just
OK we found the issue.
In the first case (pure Groovy), the annotations are placed on the fields
(always the case for Groovy) and metaClass is indeed a transient field thus
ignored.
In the second case I suspect your java class has it's annotations on getters.
So JPA expect to find annotations
oups, interesting. I don't really understand why we don't run into the problem
when there is no inheritance.
I will try and catch guillaume to talk about how to solve that.
