Non-EE mapping classes?
How do I map classes if I'm not using persistence.xml or EE? Usually you
use xml like this:
<class>tutorial.Animal</class>
but I'm using a properties file.

Actually, you should be able to call
Persistence.createEntityManagerFactory("foo", map), where "foo" is the
name of your persistence unit in a META-INF/persistence.xml file.

The JAVA agent of OpenJPA (Runtime Enhancement) needs at least one persistence.xml (or orm.xml). Meanwhile, runtime enhancement has the minimum requirement on configuration file, even you didn't put your entity class in that file.

Yes, I think so. and you have to use OpenJPA specified APIs instead of JPA standard one.
Here is an example:
OpenJPAPersistence.getEntityFactory(map);
The map instance contains the properties from local file.
Thanks

So where can I put this xml file so it will work in my jar? I'm assuming
I can then load a properties file that will override the xml settings?

In my opinion, for OpenJPA, you have to use one persistence.xml. Here is the reason.
You might create a persistence entity manager without persistence.xml, but OpenJPA used to enhance java entity classes. The JAVA agent of OpenJPA (Runtime Enhancement) needs at least one persistence.xml (or orm.xml). Meanwhile, runtime enhancement has the minimum requirement on configuration file, even you didn't put your entity class in that file.
Thanks,
Gene.
