Ok! So by this way a part of my problem is solved. The specific characters that were not recognized like %=@ are checked now. But I still can't make it work whith the unicode UTF-8 (Japanese characters for example).
That is what should enable me to recognize the unicode in the jsp pages:
for html:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>test</title>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
</head>
<body text="#000000" link="#000000" vlink="#000000" alink="#000000">
for
java:
<%@ page language="java" pageEncoding="utf8" contentType="text/html; charset=UTF-8" %>
and before getting the requesting value of the "code" parameter:
request.setCharacterEncoding("UTF-8");
I try by decoding the request too but the result is the same:
the code string is: ジポネキ
the encoded code is : %E3%82%B8%E3%83%9D%E3%83%8D%E3%82%AD
and the value requested is : ������������
Am I doing something wrong? Or does something miss me?
