Hi all ! I have read about the trouble when reading Japanese from Resource.properties file in the mail archive. Actually I had the same trouble myself too.
Finally I got through this with below solution. 1) Save the Resource.propeties file by "JIS" encoding. 2) Set the charset of jsp to "ISO2022JP", like below. <%@ page contentType="text/html; charset=ISO2022JP" %> Viewing from IE results fine. IE's encode is set to "default".
