RE: Forward to the same page

[leo mj]

hi antonio,


 It can be done by using ActionForwards.Also go tru internatinalization in 
struts
for displaying langauage :
http://www.allapplabs.com/struts/struts_internationalization.htm


in the action class use
  ActionForward forward=new ActionForward();

if(chk whther the language  combo box has been selected ){

  forward=mapping.getInputForward();

}

add internationalization code using 
<bean:messageKey>
get language to be selected using request.getAttribute("fieldName");

in ur jsp...

Regards,
Leo

Changing location

  window.location = location;
 } else {
  var pos = location.indexOf("lang=");
  if(pos != -1){
   var new_location = location.substring(0, pos + 5);
   new_location += lang;
   window.location = new_location;
  } else {
   location += "&lang=";
   location += lang;
   window.location = location;
  }
 }

It will work if you don't need the addition page (such as when dealing with
login).

Also you have to be sure, that your lang=.. parameter is in the end of
parameters line (that is true until you're not trying to add lang=..
somewhere outside). And there will be problem if your application dealing
with parameters named, for example, 'XXXlang'. All imperfections mentioned
can be removed by some little changes in script.
