Hi Daniel!
The @PersistenceContext is only used in case you have a real JavaEE container
like TomEE, WildFly, etc.
In any other case the manual creation of the EntityManagerFactory is fine.
Although I'd only create the EMF once, e.g. in a @PostConstruct method in your
@ApplicationScoped bean.
Or you use the DeltaSpike @UnitName.
I just figured that our Docs (and JavaDocs) do not yet contain my latest
changes.
By default using @UnitName("MYDB") the PersistenceConfigurationProviderImpl
will load a file persistence-MYDB.properties.
In addition you can also use deltaspike-config to override/extend those
persistence settings:
https://github.com/apache/deltaspike/blob/master/deltaspike/modules/jpa/impl/src/main/java/org/apache/deltaspike/jpa/impl/entitymanager/PersistenceConfigurationProviderImpl.java#L46
Just use a property
deltaspike.persistence.config.MYDB.some.jpa.property.
This will lead to having 'some.jpa.property' added to the EntityManagerFactory
property map.
