Hi Community,
In my login action when ever a user logs in I am putting his
user id in hash table like this
Hashtable findUser = new Hashtable();
userList.put("username",username);
servlet.getServletContext().setAttribute("userList",userList);
now I want to remove this user when his session expires in
sessionDestroyed() method of HttpSessionListener
HttpSession session = sessionEvent.getSession();
String user = (String) session.getAttribute("username");
Hashtable userList = (Hashtable)
servlet.getServletContext().getAttribute("userList");
userList.remove(user)
but I am getting NullPointerException in the following line
Hashtable userList = (Hashtable)
servlet.getServletContext().getAttribute("userList");
Please help me out
Regards,
Sreenivasula Reddy A
