protected static InputStream tryOpenCumulus4jPersistenceProperties()
public static Map<String,Object> getCumulus4jBackendProperties()
Get the backend-properties (from file "cumulus4j-backend.properties").
The backend-properties are loaded from the file "cumulus4j-backend.properties"
and used for the configuration of the backend-PersistenceManagerFactory
. This file only
contains connection-independent settings (i.e. things that should never change).
The connection-dependent settings are copied from the frontend-PMF's configuration.
Additionally, all properties in the frontend-PMF's configuration starting with "cumulus4j.datanucleus." or "cumulus4j.javax." are forwarded to the backend-PMF (without the "cumulus4j."-prefix, of course) overriding the default settings.
