Я создал следующую JSP:

<%@ page import="hu.flux.locale.LanguageToolkit" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%
Locale locale = LanguageToolkit.getLanguage(request);
//String locale = LanguageToolkit.getLanguageString(request);
%>
<fmt:setLocale value="${locale}" />
<fmt:bundle basename="hu.flux.locale.resources.TestResources">

Когда я пытаюсь зайти на страницу с этим URL:
http://localhost:8080/SamsTeachYourselfJSP/pages/ResourceBundlesJSTL.jsp?languageOverride=de_DE
Это отображается на экране:
Hello!
Welcome to our web site. Please take a moment to fill out our survey
Your locale is de_DE.
What is your name:
How old are you:
Where do you live:
Страница, очевидно, находит и использует файл свойств на английском языке вместо немецкого, хотя сервер выбрал мой параметр для установки локали на de_DE и принял команду на установку локали.
Ресурс, который я ожидаю вызвать, содержит:
# /src/hu/flux/locale/resources/TestResources_de.properties
namePrompt=Wie hei[gb]en Sie:
agePrompt=Wie alt sind Sie:
placePrompt=Wo wohnen Sie:
greetHeading=Guten Tag!
welcomeText= Willkommen bei unserer Web-Site. Bitte, dauern Sie einen Moment Um unsere Umfrage auszufüllen
submitButtonText=Senden
Я почти уверен, что проблема не в моем классе LanguageToolkit, поскольку он отлично работает с не-JSTL-версией этой страницы, но если кто-то захочет это увидеть:

Есть идеи, почему я вижу английский и как это исправить?
