How the page should redirect when we click a link using sessions

Question

Hi Friends,
I have two links namely Gujarati and English in the page. before logon to the application, when i click the Gujarati link, the total content of the page should change to Gujarati and for english as same..How to do this using sessions and Internationalization(i18n).
It can be easy if anybody is using Property files and resourcebundle.
Thank you..

Answer 1

I will give u a very simple example of using session here.
Lets say you have 2 links in your HTML or JSP page: Gujarati | English
In you nextPage.jsp, you need to do the following:
<%@ page session="true" %>
By using page directive with session attribute to true will make HTTPSession implicit object available with you in your JSP.
Now you can save your request parameter lang to this session for further identification of user's selection for the language.
This is how it can be add user selected language into sessions in JSP:
<%
session.setAttribute("Language", request.getParameter("lang"));
%>
To retrieve this value for further usage, you can use the following:
<%
String lang = (String)session.getAttribute("Language");
%>
If you are using servlet instead of JSP, you can handle the same by having following lines of code in your servlet:
To set a value or object in the session:
HttpSession session = request.getSession();
request.setAttribute("Language", request.getParameter("lang"));
to retrieve a value or object from the session:
HttpSession session = request.getSession();
String language = (String)request.getAttribute("Language");
I hope this helps to solve your problem for having selected language using sessions. Once you know which language the user has selected you can use internationalization to convert your pages to other languages.
