Title: Localized ResourceBundle subclasses
Date: 2007-05-14
Tags: JDK
lang: en

When working on Mule's i18n support I stubled over a hidden gem in java. The ResourceBundle's `getResourceBundle` method will build a candidate name and look for a class **with this name** in the runtime before resorting to loading properties files. I'd like to play around with this feature a bit, currently I'm thinking of using plain java classes as storage for error messages. With proper class hierarchies the need to duplicate each and every message should be gone then, as the wonder of overridden methods kicks in.  See [ResourceBundle's getBundle method description](http://java.sun.com/j2se/1.4.2/docs/api/java/util/ResourceBundle.html#getBundle(java.lang.String, java.util.Locale, java.lang.ClassLoader)) for detailed documentation.
