Thanks Jan for your detailed explanation. I think I finally find the right document which is under the standard-doc of the taglib.
1) I follow the instruction and insert the line: <%@ taglib uri="http://java.sun.com/jstl/ea/fmt"; prefix="fmt" %> in a JSP file, and the lines: <context-param> <param-name>javax.servlet.jsp.jstl.i18n.basename</param-name> <param-value>mm</param-value> </context-param> in the web.xml file. I also have three resource files in place: mm.properties, mm_en.properties, and mm_zh.properties. I get an exception when I try to bring up the jsp page (see the error message on the bottom). After I replace the format tag lib of JSTL with the followings: <%@ taglib uri="http://jakarta.apache.org/taglibs/i18n-1.0"; prefix="i18n" %> <i18n:bundle baseName="mm" id="bundle"/> The English version displays properly under the browser language setting with ?en? higher than ?zh?. To my understanding, the code base of i18n and fmt tag libraries are the same (You wrote it). I guess the problem is the setting. Would you please point out where I did wrong. 2) When 'zh' is higher than 'en' in the browser's language setting, all messages in the resource file are displayed as ???. And I find out the locale and character setting on the page is en_US and ISP-8859-1 respectively. All jsp files have the character set as UTF-8 since each jsp file started with <%@ page contentType='text/html; charset=UTF-8' %>. All JSP file is formed from several regions: banner, side bar, footer, and body. How can I have the right locale and character set in the JSP file? Thanks very much for your kindly help.
