The two methods you have to override when subclassing ResourceBundle
are getKeys ( ) and handleGetObject ( ). Here, then, is the code for MyRe-
sourceBundle :

package stripesbook.ext;
public class MyResourceBundle extends ResourceBundle {
private Locale locale;
public MyResourceBundle(Locale locale) {
this .locale = locale;
}
@Override
public Enumeration<String> getKeys() {
return null ;
}
@Override
protected Object handleGetObject(String fullKey) {
Object result = null ;
// Look for a class name in the full key
for ( int i = fullKey.length() - 1; i > 0; i--) {
if (fullKey.charAt(i) == '.') {
String className = fullKey.substring(0, i);
try {
Class.forName(className);
// Found a class name, use the rest as a key
String key = fullKey.substring(i + 1);
result = getResult(locale, className, key);
}
catch (ClassNotFoundException exc) {
}
}
}
if (result == null ) {
// Found nothing, try the application's default bundle
String name=DefaultLocalizationBundleFactory.BUNDLE_NAME;
result = getResult(locale, name, fullKey);
}
return result;
}
// Just returns null if the bundle or the key is not found,
// instead of throwing an exception.
private String getResult(Locale loc, String name, String key) {
String result = null ;
ResourceBundle bundle = ResourceBundle.getBundle(name, loc);
if (bundle != null ) {
try { result = bundle.getString(key); }
catch (MissingResourceException exc) { }
}
return result;
}
}
