Transfer value via session
Need to import package:
Import javax.servlet.http.httpservletRequest;
Import javax.servlet.http.httpservletResponse;
Import javax.servlet.http.httpsession;
Put the value into the session:
HttpSession session = request.getations ();
Session.setttribute ("User_Name", Username;
Remove the value in the session:
HttpSession session = request.getations ();
String username = (string) session.getattribute ("user_name");
