The facesMessages component is a super-convenient way to display success or failure messages to the user. The functionality we just described also works for faces messages:

@Name("hello")
@Stateless
public class HelloBean implements Hello {
    @In FacesMessages facesMessages;
    
    public String sayIt() {
        facesMessages.addFromResourceBundle("Hello");
    }
}

This will display Hello, Gavin King or G'day, Gavin, depending upon the user's locale.
