change locale not working

[Mik Montana]

Hi all,

I'm trying to develop a multilanguage web application, I found the instruction to change the language at this link http://static.springsource.org/spring/docs/2.5.x/reference/mvc.html#mvc-localeresolver and I have only add this code on my dispatcher-servlet :
Code:

<bean id="localeChangeInterceptor"
          class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="siteLanguage"/>
    </bean>

    <bean id="localeResolver"
          class="org.springframework.web.servlet.i18n.CookieLocaleResolver"/>

    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="interceptors">
            <list>
                <ref bean="localeChangeInterceptor"/>
            </list>
        </property>
        <property name="mappings">
            <props>
                <prop key="login.htm">indexController</prop>
		<prop key="uploadfile.htm">fileUploadController</prop>
                <prop key="successUpload.htm">successUploadController</prop>
            </props>
        </property>
    </bean>

and I try to change the language with this link : index.htm?siteLanguage=en_EN
but is not working.

Please help me....
