Hi
I have a problem with using session object and cookies with jsps.
The problem is that I have set the session max inactive interval to 5 hours
(300 mins * 60 secs) and after a certain time - the shortest being 5 mins,
the session times out. When I access a session variable using people_id =
(String) session.getAttribute("people_id"); I get a nullpointerException.
Anyone here knows whats wrong. Here is a sniplet of my code.
in the login.jsp file
int sessionTime = 300*60; //300 mins session time
session = request.getSession(true);
session.setMaxInactiveInterval(sessionTime);
session.setAttribute((String) "group_id",group_id);
session.setAttribute((String) "role_id", role_id);
session.setAttribute((String) "accessTime", new Long(accessTime));
in other files
session = request.getSession();
String people_id = (String) session.getAttribute("people_id");
etc etc.
I have used the following function to detect whether the session is null or
not
if (session.getAttribute("people_id")!=null) {
}
else {
throw new Exception("no people access. ");
}
Sometimes this works and other times, a null pointer exception is raised,
eg the 'no people access' is raised. Is this a problem in Resin? Or a
problem with my source?
