The JPOX system is internationalisable hence messages (to log files or exceptions) can be displayed in multiple languages.
Currently JPOX contains localisation files in the default locale (English), but can be extended easily by adding localisation
files in languages such as Spanish, French, etc. The internationalisation operates around the org.jpox.util.Localiser class
that is responsible for generating the messages in the specified locale. Each class needs to instantiate a Localiser
private static final Localiser LOCALISER=Localiser.getInstance("org.jpox.store.Localisation");
and then output messages via
LOCALISER.msg("StoreManager.SchemaDataInitialise",schemaName,autoStartMechanism)
The messages themselves are contained in a file for each package. For example, with the above example, we have
org.jpox.store.Localisation.properties. This contains entries such as
StoreManager.SchemaDataInitialise=Initialising Schema "{0}" using "{1}" auto-start option
So the 2 parameters specified in the LOCALISER.msg call are inserted into the message. The language-specific parts are
always contained in the Localisation.properties file.
To extend the current system to internationalise in, for example, Spanish you would add a file
org.jpox.store.Localisation_es.properties and add an entry such as
StoreManager.SchemaDataInitialise=Inicializando la esquema "{0}" con la opción de empezar "{1}"
With this file installed, anybody running an application where the JDK is running in Spanish as default locale would see
the above Spanish message. It is intended to include such files in a future release.
