I wish to be able to set @Cache(coordinationType=CacheCoordinationType.XXX) for all entities by default.
Is there anyway to do this in the persistence.xml file for the Persistence Unit. If not can it be done through a sessions.xml/project.xml/SessionCustomizer?

Thanks.

You can use a SessionCustomizer,

for (ClassDescriptor descriptor : session.getDescriptors().values()) {
descriptor.setCacheSynchronizationType(ClassDescriptor.INVALIDATE_CHANGED_OBJECTS);
}

You should also be able to use a @MappedSuperclass.

Please log an enhancement to have default cache options exposed in the eclipselink orm.xml file or persistence unit properties.
