Internalization of JSF project on WebSphere 7 - internationalization

Question

I'm trying to implement loading Resource Bundles for JSF application from DB, following the sample: internationalization in JSF with ResourceBundle entries which are loaded from database
For the test I coded getItSomehow() just as create HashMap and fill it with key "hello_world" and value "["+locale+"]"+"hello world"
The sample works fine when I deploy it on Glassfish3.
But when I use WebSphere AS 7, the jsf page is displayed correctly only for the first time. Opening the jsf page in other browsers (with other prefered language selected) I receive the respond always in the locale of first run.
While debugging, I found the difference in implementation of ResourceBundle.java: Glassfish uses this class provided in rt.jar of the JDK1.6; but WebSphere has this class inside java.util.jar
The ResourceBundle (of WebSphere) called from ApplicationResourceBundle.getResourceBundle() calls handleGetBundle() and finally invokes my.i18n.DbResourceBundle$DBControl.newBundle() .
Called second (and further) time with different locale it doesn't invoke my override but just returns the same bundle created for first locale.
The question: is it possible to code internalizable jsf web-application deployed on WebSphere AS 7.0.07, not digging nor hacking into internals of the AS?
(environment: Windows XP, WebSphere AS 7.0.0.7, jdk1.6.0_24, jsf 2.1.4)

You can provide a specific implementation of ResourceBundle.
Here an example that gets the current locale each time JSF invokes the ResourceBundle methods:
package my.company.jsf.util;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Locale;
import java.util.Map;
import java.util.ResourceBundle;
import javax.faces.context.FacesContext;
public class MyBundle extends ResourceBundle {
private static final Map<Locale, ResourceBundle> RB_CACHE = new HashMap<Locale, ResourceBundle>();
private static final String BUNDLE_NAME = "my-messages";
public MyBundle() {
}
#Override
public Enumeration<String> getKeys() {
ResourceBundle rb = getResourceBundle();
final Iterator<String> it = rb.keySet().iterator();
return new Enumeration<String>() {
#Override
public boolean hasMoreElements() {
return it.hasNext();
}
#Override
public String nextElement() {
return it.next();
}
};
}
#Override
protected Object handleGetObject(String key) {
ResourceBundle rb = getResourceBundle();
return rb.getObject(key);
}
private ResourceBundle getResourceBundle() {
Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();
ResourceBundle rb = RB_CACHE.get(locale);
if (rb == null) {
rb = ResourceBundle.getBundle(BUNDLE_NAME, locale);
RB_CACHE.put(locale, rb);
}
return rb;
}
}
and in your faces-config.xml put:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
<application>
<resource-bundle>
<base-name>my.company.jsf.util.MyBundle</base-name>
<var>MSG</var>
</resource-bundle>
</application>
</faces-config>
We had your same problem and this solution worked for us with Windows Server 2008, WebSphere AS 7.0.0.19, jdk1.6.0_29, jsf 2.1.5
