How to create an injectable Resourcebundle with Weld

[ifischer]

In my Java EE 6 application, i'm often dealing with the ResourceBundle in my Beans to get localized messages. To get the correct ResourceBundle, i always have to obtain it in this way:

FacesContext facesContext = FacesContext.getCurrentInstance();
String sessionErrorString = ResourceBundle.getBundle("/messages", 
     facesContext.getViewRoot().getLocale()).getString("sessionTimeOut")

So i always have to obtain the instance of FacesContext and resolve the locale.
As this is not very elegant, i looked into the Seam 3 Source and found some nice producer classes, i.e. for the Locale and for the FacesContext.
Now i want to use them to create a ResourceBundle-Producer, so i can shorten the above code by injection to the following:

@Inject ResourceBundle bundle;
(...)
public void test() {
  log.info(bundle.getString("myMessage"));
}

So these are the classes i obtained from the current Seam 3-trunk. I need them for my BundleResolver:

FacesLocaleResolver:

public class FacesLocaleResolver {
   @Inject
   FacesContext facesContext;

   public boolean isActive() {
      return (facesContext != null) && (facesContext.getCurrentPhaseId() != null);
   }

   @Produces @Faces
   public Locale getLocale() {
      if (facesContext.getViewRoot() != null) 
         return facesContext.getViewRoot().getLocale();
      else
         return facesContext.getApplication().getViewHandler().calculateLocale(facesContext);
   }
}

FacesContextProducer:

public class FacesContextProducer {
   @Produces @RequestScoped
   public FacesContext getFacesContext() {
      FacesContext ctx = FacesContext.getCurrentInstance();
      if (ctx == null)
         throw new ContextNotActiveException("FacesContext is not active");
      return ctx;
   }
}

And this shall be my ResourceBundle-Resolver:

public class ResourceBundleProducer {
  @Inject       
  public Locale locale;
  
  @Inject       
  public FacesContext facesContext;

  @Produces
  public ResourceBundle getResourceBundle() {
    ResourceBundle.getBundle("/messages", facesContext.getViewRoot().getLocale() )
  }
}

Unfortunately, my BundleResolver doesn't work, as ResourceBundle is not Serializable. I'm getting the following Error from Weld when trying to access a JSF-page which calls a bean that uses my ResourceBundle:

Caused by: org.jboss.weld.IllegalProductException: WELD-000054 Producers cannot produce non-serializable instances for injection into non-transient fields of passivating beans\\n\\nProducer\: org.jboss.weld.bean-/D:/Program Files (x86)/GlassFish-Tools-Bundle-For-Eclipse-1.2/glassfishv3/glassfish/domains/teachernews/applications/teachernews/-ProducerMethod-services.producers.ResourceBundleProducer.getResourceBundle()\\nInjection Point\: field web.PersonHome.bundle

Are there any ways to get my ResourceBundleResolver to work? Can i somehow wrap ResourceBundle and make it serializable? Or are there any other mechanisms to get a similar functionality?
Thanks in advance!

there is an error in my code, the last line of ResourceBundle Resolver should of course be 

return ResourceBundle.getBundle(/messages, facesContext.getViewRoot().getLocale() )

bump
is there really no way or workaround to inject a non-serializable class? Or to create a producer for a non-serializable class?
I got the same problem with Flash from Facescontext, which is also not serializable, but i would like to create a Flash-Producer in the same way like the one above.

THE SOLUTION:

Just got an answer for this  question on Stackoverflow:
The ResourceBundle has to be injected as a transient attribute, like this:

@Inject
transient Resourcebunble bundle;

Hi Ingo,

where does the @Faces in FacesLocaleResolver come from?

There is no @Faces available in CDI
