I want to create a Producer that makes it possible to inject a java.util.ResourceBundle into any class in order to get localized Strings easily. My ResourceBundle-Producer looks like this:
public class ResourceBundleProducer {
@Inject
public Locale locale;
@Inject
public FacesContext facesContext;
@Produces
public ResourceBundle getResourceBundle() {
return ResourceBundle.getBundle("/messages", locale )
}
}
The Injection of Locale and FacesContext works (took the corresponding producers from the Seam 3 Alpha Source). But unfortunately, ResourceBundle is not Serializable and therefore can't be produced in this way. 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? Or are there any other mechanisms to get a similar functionality? Thanks in advance!
EDIT:
Okay, i'll spent some of my hardly earned points ;) Will also accept a good workaround for this issue!
I got another example where creating a Producer doesn't work: a FlashProducer. A FacesContext-Flash also cannot be produced because Flash isn't serializable.
Well, First of all ResourceBundle is not Serializable. See here. And The message is clear
cannot produce non-serializable instances for injection into non-transient fields of passivating beans
passivating beans ??? I Think web.PersonHome is Either a Stateful Session Bean or a @ConversationScoped bean. Am i right ??? If so you should mark your bundle property as transient
private transient @Inject ResourceBundle bundle;
