Getting User Name from Within HttpSessionListener

Question

I would like to get the username from within HttpSessionListener.sessionCreated(). When I say username, I mean specifically that name that is returned by HttpServletRequest.getRemoteUser().

Obviously, there must have been a HttpServletRequest object that caused the session to be created (and hence the sessionCreated() call). But how do I access it from within sessionCreated()? The HttpSessionEvent object passed into sessionCreated() appears to provide no way to get at the HttpServletRequest object that caused the session to be created.

Answer 1

The HttpSessionListener does not have access to the HttpServletRequest object because it is invoked when no request has been made—to notify of session destruction or creation.

So, a Filter would be better places where you can add username = request.getRemoteUsr() into session.

Example - Filter Code

String username = request.getRemoteUsr() ;
session.setAttribute("username",username);

and then retrive this username in sessionCreated method as

String username = (String)session.getAttribute("username");

i hope you will get the same username of the same request which has created this session in HttpSessionListener sessionCreated() method.
