I want to use httpsession in Spring 3 MVC..i have searched all the web and got this solution..at http://forum.springsource.org/showthread.php?98850-Adding-to-stuff-to-the-session-while-using-ResponseBody
Basically, My application auto authenticates user by getting winId and authorizes through LDAP..(Its a intranet site)
Here is the flow of the application,
1. User enters Aplication url (http://localhost:8082/eIA_Mock_5)
it has a welcome page (index.jsp)
Index.jsp gets winId through jQuery and hits login.html (through Ajax) and passes windowsId
login.html (Controller) authenticates through LDAP and gives back 'Valid' String as a response
javascript, upon getting the correct response, redirects/loads welcome page i.e. goes to localhost:8082/eIA_Mock_5/welcome.html
Now, i have filter associated with it..which checks for is session valid for each incoming request..Now the problem is even though i set data on to httpsession, yet the filter or any other controller fails to get the data through session as a result it doesnt proceeds further..
here is the code..and could you suggest what is wrong actually ??
Home_Controller.java
@Controller
public class Home_Controller {
public static Log logger = LogFactory.getLog(Home_Controller.class);
