Hello,

I am getting following error:

I am opening two sessions at a time

HttpSession newSession = req.getSession(true);

if (newSession.isNew()) {
String cvId = (String) newSession.getAttribute("cvId");			
	
//insert into db by getting & setting user Id from db			

}//newSession
newSession.invalidate();

but before this newSession I already have opened session as following:

HttpSession session=req.getSession();			
	session.setAttribute("userId","1185");

this session is closed at the end when all tasks are done that throws the aforementioned stackTrace. I stuck that using newSession.invlidate() why session instance is also invalidating?

Thanks in anticipation

req.getSession(true) does not create a new session. It will create a new session only if there is no existing session. So in your case when you do req.getSession(true) it will return a reference to the same session you had before. If you invalidate that session and then try to do stuff with the same session, it wont work. It might be a different reference to the session, but still it is pointing the session that was just invalidated.
