Subject Re: Problem with <fmt:bundle>
Date Wed, 22 Mar 2006 10:13:02 GMT

I ran up against this problem in my application.  After some digging I 
boiled it down to the fact that the servlet spec / tomcat versions I 
was using didn't allow me to provide a Locale to character encoding 
mapping, and when the fmt tags do pretty much anything, they end up 
setting the Locale, which in turn sets the character encoding.  I think 
I read somewhere that some version of the servlet spec allows you to 
specify Locale to character encoding mappings in the web.xml file, but 
for what I'm using (2.3 on tomcat 4.1) what I had to do was create a 
custom CharSetMapper and specify it on the <context> tag in my 

My charset mapper ignores whatever locale you ask for a mapping for and 
returns UTF-8 as the charset every the time.  It seemed extreme, but 
it's what I wanted.  I compiled this and put it in 

package com.peoplesarchive.tomcat;

import java.util.Locale;

import org.apache.catalina.util.CharsetMapper;

public class UTF8CharsetMapper extends CharsetMapper {
     public UTF8CharsetMapper() {

     public UTF8CharsetMapper(String name) {

     public String getCharset(Locale locale) {
         return "utf-8";

server.xml fragment
path="" docBase="ROOT" debug="0" reloadable="true" />

hope this helps
