Hello,

in Struts-config.xml.
This mapping can be called from many page so i can't

You can calculate query string for current page

<%
   String sourceURL = null;
   StringBuffer URL = HttpUtils.getRequestURL(request);
   String queryString = request.getQueryString();
   if( (queryString!=null) && (queryString.length()>0) ) {
    URL.append("?");
    URL.append( queryString );
   }
   sourceURL = URL.toString();

%>

for example. But this will work only if you call your page directly
and not use forward from action.
If you use forward (without redirect) then you must calculate path to
redisplay page in action class, store it in request scope and use this
string as parameter for language switch. Language switch action take
this query string and make forward to it after language switching.
