Change language at runtime

Question

Hi there,
I have a rather difficult question I think.
I work with jsp and struts and I want my users to change the language of the content by clicking on a button.
I have the following method in my action:
public ActionForward execute(ActionMapping mapping,ActionForm form,     HttpServletRequest request,     HttpServletResponse response)
                                        throws Exception {
          HttpSession session= request.getSession();          
          System.out.println(request.getLocale().getLanguage()+" bla");          
          Locale locale = (Locale) session.getAttribute(Globals.LOCALE_KEY);
          System.out.println(locale.getCountry()+" "+locale.getLanguage());                         
          String language=request.getParameter("language");                         
          locale = new Locale(language);          
          session.setAttribute(Globals.LOCALE_KEY, locale);          
          Config.set(session, Config.FMT_LOCALE, locale);
          return new ActionForward("/pm_main.jsp");     
Why doesn't this work?
I just want to change the users locale, so the site gets his resources from the new resources.properties file...
I hope someone knows where I'm getting at!
Thanks

You are replacing Globals.LOCALE_KEY in the session. You are doing this in the execute method of the action. But execute is not really the first thing that happens, nor the last, in the process of receiving the request and sending the response. So if Struts for some reason sets this value in the session after execute (I'm not sure why it would) then it would overwrite whatever you put there.
