Using One Page for Multiple Locales

Example 14-1 shows the poll.jsp page. That’s where the magic of locale selection happens, and the selection is then used to produce text in the corresponding language throughout the page.

Example 14-1. Language selection and vote page (poll.jsp)
<%@ page contentType="text/html" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%-- 
  Set the locale to the selected one, if any. Otherwise, let the
  <fmt:setBundle> action pick the best one based on the Accept-Language
  header.
--%>
<c:if test="${param.language == 'en'}">
  <fmt:setLocale value="en" scope="session" />
</c:if>
<c:if test="${param.language == 'sv'}">
  <fmt:setLocale value="sv" scope="session" />
</c:if>
<c:if test="${param.language == 'de'}">
  <fmt:setLocale value="de" scope="session" />
</c:if>
<fmt:setBundle basename="pages" var="pagesBundle" />
<fmt:setBundle basename="labels" scope="session" />
