URIEncoding

Hello,

I have an application which is running in local machine and it work perfect. I installed my application in the server to make it available for all. In the server we have tomcat running and provide services for many instances. After I played my application in the server, I had problem with query which have special language character. After long time, I could find where is the problem. The problem was in server.xml where the URIEncoding is set to "UTF-8". I made test and just removed this line or set it to "ISO-8859-1" and all was perfect. My question here is it possible to set the URIEncoding for each instance or is it possible to set it some where else. I send the query from jsp page to the servlet. in my jsp page the charset=ISO-8859-1". I tried to make all utf-8 but I couldn't success. I tried the filter approach but also doesn't help:

<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>servlet.CharsetFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>ISO-8859-1</param-value>
</init-param>
</filter>


<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<servlet-name>action</servlet-name>
</filter-mapping>

Any hint will be appreciated.
