Question

I’m trying to get values from a JSP using getParameter which includes ü,é,à etc. But get wrong values in servlet. I’ve checked the content type with firebug and found that

Content-Type    text/html;charset=UTF-8

checked the POST section with firebug and found the correct value there, when I try to access it in servlet it is wrong. Gives ö instead of ö

req.getCharacterEncoding(); 

returns null.

Tried with setting

 req.setCharacterEncoding("UTF-8");

at the beginning of servlet but didn’t help.

edited:

req.getParameter("myValue").getBytes("8859_1"), "utf-8")

above line gives correct value.

adding the following to web.xml fixed the issue…

<filter>
    <filter-name>charsetFilter</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>
</filter>

<filter-mapping>
    <filter-name>charsetFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
