Easiest way to do it is to create a custom resource loader like this:
public class DatabaseResourceLoader implements IStringResourceLoader {
(...)
@Override
public String loadStringResource(Class<?> clazz, String key, Locale
locale, String style, String variation) {
return messageService.getStringResource(key,
locale.getLanguage());
}
@Override
public String loadStringResource(Component component, String key,
Locale locale, String style, String variation) {
return messageService().getStringResource(key,
locale.getLanguage());
}
}
In your application init class you need to add the resource loader:
getResourceSettings().getStringResourceLoaders().add(new
DatabaseResourceLoader()); // db lookups performed only if key is
missing from properties files
or
getResourceSettings().getStringResourceLoaders().add(0, new
DatabaseResourceLoader()); // db lookups are first, you can override
translations from properties in the db
Note: you don't need to worry about caching, wicket will cache results
from resourceloaders. If they change in the db, you can call
Application.get().getLocalizer().clearCache() to invalidate it.

Most of our error messages are in property files, but we have a set of them
that we need to draw from a database. I'd like to add them to the resources
programmatically in the Application object at startup so that pages don't
know any difference between whether it was sourced from property files or
the database.
How can I add them to whatever pool the app is pulling from when I do
getString(name)?
