JSP源文件如下：

<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.awt.*" %>

<%
String languageDefault = Locale.getDefault().getLanguage();
String countryDefault = Locale.getDefault().getCountry();

Locale defaultLocale = null;
String charset = null;
if (languageDefault == "en" || languageDefault.equals("en")){
        defaultLocale = Locale.ENGLISH;
        charset = "iso-8859-1";
}else if (countryDefault == "CN" || countryDefault.equals("CN")){
        defaultLocale = Locale.SIMPLIFIED_CHINESE;
        charset = "gb2312";
}else if (countryDefault == "TW" || countryDefault.equals("TW")){
        defaultLocale = Locale.TRADITIONAL_CHINESE;
        charset = "big5";
}else{
        System.out.println("LanguageDefault not equals en.CountryDefault not equals TW or CN");
}

if (session.isNew()){
        session.setAttribute("locale",defaultLocale);
        session.setAttribute("charset",charset);
}else{
        String language = request.getParameter("language");
        if (language == null || language.equals(null)){
                session.setAttribute("locale",defaultLocale);
                session.setAttribute("charset",charset);
        }else{
                Locale locale = null;
                if (language == "Locale.SIMPLIFIED_CHINESE" || language.equals( "Locale.SIMPLIFIED_CHINESE")){
                        locale = Locale.SIMPLIFIED_CHINESE;
                        charset = "gb2312";
                }else if (language == "Locale.TRADITIONAL_CHINESE" || language.equals( "Locale.TRADITIONAL_CHINESE")){
                        locale = Locale.TRADITIONAL_CHINESE;
                        charset = "big5";
                }else if (language == "Locale.ENGLISH" || language.equals( "Locale.ENGLISH")){
                        locale = Locale.ENGLISH;
                        charset = "iso-8859-1";
                }
                session.setAttribute("locale",locale);
                session.setAttribute("charset",charset);
        }
}

Locale locale = (Locale)session.getAttribute("locale");
ResourceBundle messagesBundle = ResourceBundle.getBundle("FullTextSearch.MessagesBundle",locale);
String localeCountry = locale.getCountry();
String localeLanguage = locale.getLanguage();

if(localeLanguage == "en"){
        response.setContentType("text/html; charset=ISO8859-1 ");

        response.setContentType("text/html; charset=big5");

属性文件如下（英文,简体中文，繁体中文，默认）(放在包FullTextSearch下面)
MessagesBundle_en.properties
username=administrator
simplifiedChinese=SimplifiedChinese
traditionalChinese=TraditionalChinese
english=English

MessagesBundle_zh_CN.properties
username=\u7cfb\u7edf\u7ba1\u7406\u5458
simplifiedChinese=\u7b80\u4f53\u4e2d\u6587
traditionalChinese=\u7e41\u4f53\u4e2d\u6587
english=\u82f1\u6587

MessagesBundle_zh_TW.properties
username=\u7cfb\u7d71\u7ba1\u7406\u54e1
simplifiedChinese=\u7c21\u9ad4\u4e2d\u6587
traditionalChinese=\u7e41\u9ad4\u4e2d\u6587
english=\u82f1\u6587

MessagesBundle.properties
username=administrator
simplifiedChinese=SimplifiedChinese
traditionalChinese=TraditionalChinese

备注：
汉字转换为ascii码用命令：native2ascii.exe
本程序可以正常运行～～～
