One solution is for each page to have a hidden field that contains it's relative path. Then you can forard to that page after you have changed the locale.

Subject: ActionServlet to change language ?
Hi all,
I want to use a simple action to change the language in a site,
but I would like this feature to be available on all pages of the site.
I'm using a template, and the same menu (with language selection)
is included in each page.
My question is : When a visitor decide to change the language,
how could I know the URL where he was and where I had to come
back ?
In other words, how can I complete the following code ?
+++++++++++++++++++++++++++++++++++++++++++++
public final class ChangeLang extends Action {
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// Extract parameters we will need
String requested = (String)request.getParameter( "lang" );
if( requested == null )
return (mapping.findForward("error"));
if( requested.equalsIgnoreCase( "FR" ) )
setLocale( request, Locale.FRANCE );
if( requested.equalsIgnoreCase( "UK" ) )
setLocale( request, Locale.UK );
if( requested.equalsIgnoreCase( "DE" ) )
setLocale( request, Locale.GERMAN );
return ( ????? );
}
protected void setLocale( HttpServletRequest request, Locale locale
)
{
HttpSession session = request.getSession(false);
if (session != null)
session.setAttribute(Action.LOCALE_KEY, locale);
}
}
+++++++++++++++++++++++++++++++++++++++++++++
In my strus-config.xml :
+++++++++++++++++++++++++++++++++++++++++++++
<action-mappings>
<action path="/ChLang" actionClass="classes.ChangeLang">
<forward name="error" path="/error.jsp"/>
</action>
</action-mappings>
+++++++++++++++++++++++++++++++++++++++++++++
My menu :
+++++++++++++++++++++++++++++++++++++++++++++
<%@ taglib uri='/WEB-INF/struts-html.tld' prefix='html' %>
<table width="100%">
<tr>
<td>
Select Language :
<html:link page="/ChLang.do?lang=FR">FR</html:link> |
<html:link page="/ChLang.do?lang=EN">EN</html:link> |
<html:link page="/ChLang.do?lang=NL">NL</html:link> |
<html:link page="/ChLang.do?lang=D">D</html:link>
</td>
</tr>
</table>
+++++++++++++++++++++++++++++++++++++++++++++
Thanks.
