Thanks Jan for your response.
To my understanding, when I use the i18n tags from JSTL, I don't need to write any
class to get locale information
stored. Only task is to configure the locale information file. Please point it out if
I am wrong.
If I need to use the PropertyResourceBundle class as the followings (this class,
according to the JDK document, can't
be subclassed by the way):
import java.util.Enumeration;
import java.util.Locale;
import java.util.MissingResourceException;
import java.util.ResourceBundle;
import java.util.PropertyResourceBundle;
import javax.servlet.ServletRequest;
import javax.servlet.jsp.JspException;
public class BundleLocator {
public PropertyResourceBundle locateBundle(ServletRequest request,
String base)
throws JspException {
Enumeration en = request.getLocales();
Locale defaultLocale = Locale.getDefault();
PropertyResourceBundle fallbackBundle = null;
try {
fallbackBundle = (PropertyResourceBundle)(ResourceBundle.getBundle(base,
defaultLocale));
}
catch(MissingResourceException ex) {
throw new JspException(ex.getMessage());
}
while(en.hasMoreElements()) {
Locale locale = (Locale)en.nextElement();
PropertyResourceBundle bundle = null;
try {
bundle = (PropertyResourceBundle)ResourceBundle.getBundle(base, locale);
}
catch(MissingResourceException ex2) {
// ignore missing bundles ...
continue;
}
if(bundle != fallbackBundle)
return bundle;
if(fallbackBundle != null && bundle == fallbackBundle) {
String lang = locale.getLanguage();
String defaultLanguage = defaultLocale.getLanguage();
if(lang.equals(defaultLanguage))
return bundle;
}
}
return null;
}
}
I can write my own tag and don't need use the JSTL.
At this point, I am very frustrated by the fact of lacking JSTL documentation. I have
searched all possible places and
not much helpful information available. The document comes with JSTL doesn't help
much. And the jwsdp document
mentions JSTL, but still not much on i18n. I guess that I shall use i18n tags other
than JSTL.5/17/2002 12:53:47 AM,
