I set CharacterEncodingFilter as the first filter in my web.xml:

<filter>  
 <filter-name>encodingFilter</filter-name>  
 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
 <init-param>  
    <param-name>encoding</param-name>  
    <param-value>UTF-8</param-value>  
 </init-param>  
 <init-param>  
    <param-name>forceEncoding</param-name>  
    <param-value>true</param-value>  
 </init-param>  
</filter>  
<filter-mapping>  
 <filter-name>encodingFilter</filter-name>  
 <url-pattern>/*</url-pattern>  
</filter-mapping>

and in my JSPs this:

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8" isELIgnored="false" %>

and this:

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

But, for example, Tá passed from a JSP form back to a controller and then back out to a JSP again becomes: T%E

I'm done hours of Google searches but can't find the answer to this problem. Any help would be appreciated.

    Does your controller do anything with the form data such as store it in a database, or does it simply put it back into the JSP? In other words, could this be a problem with the encoding on your database connection? – gutch Dec 17 '10 at 05:36

    Are you using ajax to send the form and receive the data? – Javi Dec 17 '10 at 08:18

    Are you sure your browser sends the correct headers (you can use Firebug)? Is the method of your form GET or POST? – sinuhepop Dec 17 '10 at 10:57

If you are on Tomcat you might not have set the URIEncoding in your server.xml. If you don't set it to UTF-8 it won't work. Definitely keep the CharacterEncodingFilter. Nevertheless, here's a concise checklist to follow. It will definitely guide you to make this work.

If CharacterEncodingFilter or the filter you implement is at the top of web.xml, be sure to also have the <filter-mapping> elements for the CharacterEncodingFilter in the xml appear before other <filter-mapping> elements for other filters.

Took me a long time to figure that out. Could be useful for someone.
