Once you have annotated your domain objects (Chapter 4, Annotating Domain Objects), re-implemented your
repositories for JPA (Chapter 5, Implementing Repositories) and - if necessary - written
UserTypes for any custom value types (Chapter 6, Supporting Custom Value Types), then you are ready to deploy
your application. This consists of configuring both Naked Objects (telling
it to use JPA Objects), and then configuring
Hibernate as the underlying JPA provider (telling it
where the database is). After that, you (or your DBA) is ready to install
the database schema and (if necessary) to populate the database using the
fixtures you'll have developed for prototyping.
The Naked Objects framework is configured using the
nakedobjects.properties file. There are three main
property settings that need specifying:
specify the JPA Objects persistor
nakedobjects.persistor=org.starobjects.jpa.runtime.persistence.JpaPersistenceMechanismInstaller
This specifies the class to acts as the "installer" (basically, a factory) for the persistence mechanism.
specify the JPA Objects reflector
nakedobjects.reflector=org.starobjects.jpa.metamodel.specloader.JpaJavaReflectorInstaller
This specifies the class to acts as the "installer" (basically, a factory) for an updated version of the reflector; the component that builds the Naked Objects metamodel. This is needed so that JPA Objects can interrogate the Naked Objects metamodel for JPA annotations when persisting domain objects.
disable bytecode providers
nakedobjects.reflector.class-substitutor=org.nakedobjects.metamodel.specloader.classsubstitutor.ClassSubstitutorIdentity nakedobjects.persistor.object-factory=org.nakedobjects.runtime.persistence.objectfactory.ObjectFactoryBasic
The first of these components is the bytecode provider, the second is a related component that is normally used to filter out the bytecode-generated subclasses.
register repositories
The JPA repository implementations should be specified for nakedobjects.services key. For example:
nakedobjects.services.prefix = org.starobjects.jpa.testapp nakedobjects.services = service.employee.EmployeeRepositoryJpa, service.claim.ClaimRepositoryJpa
