struts2 - struts 2 and sitemesh localization -

i using struts 2 , sitemesh. can change locale in login page without problem setting request parameter named 'request_locale' parameter. in other pages using sitemesh decorating header , footer. , tried set same parameter other pages no luck. these of other codes tried in login action:

request.getsession(false).setattribute("ww_trans_i18n_locale", newlocale); actioncontext.getcontext().setlocale(newlocale); session.put(i18ninterceptor.default_session_attribute, newlocale); 

when write out these settings see ok. when write out

<c:out value="${pagecontext.request.locale.language}"/> 

it showing browsers accept-language , doesnt make localization. how can make localization work sitemesh?

i tried redirect login action action named home request locale parameter , action redirects index.jsp. ok now. , set default action home action when user enters root page address bar activing home action i18n interceptor , intercoptors becaming active. login.action in struts.xml:

<action name="login" class="wateron.login.loginaction" >         <result type="redirectaction">             <param name="actionname">home?request_locale=${request_locale}</param>             <param name="namespace">/</param>         </result>  </action> 

and home action in struts.xml :

<package name="default" extends="struts-default" namespace="">     <default-action-ref name="home" />     <action name="home">         <result>/index.jsp</result>          </action> </package>
