Session Timeout
Hey Everyone,
I am trying to use a custom session timeout JSP. To do this, I extended
"RequestProcessor" and overrode "processPreprocess" and added the following
code:
HttpSession sess = req.getSession(false);
if(sess == null){
// even when the session IS timed out, I never get here.
String uri = "/myapp/sessiontimeout.jsp";
try{
doForward(uri, req, resp);
}catch(Exception ex){}
return false;
}
The problem is, even when I know the session was expired, I never get a null
session. Am I missing something?
Thanks
John

I think I found the offending code. It is located in the Struts
RequestProcessor.processLocale method (which is called *before* the
pre-process). In that method is the following code:
// Has a Locale already been selected?
HttpSession session = request.getSession();
So I will *always* get a non-null session when I get control in the
processPreprocess method.
There doesn't seem to be a hook before any processing is done.

A new session is created when you request a new session somewhere,
it's not created automatically. However, there could be a filter,
request processor, action, or JSP somewhere that does a
request.getSession() or .getSession(true) (or '... session="true"...'
in JSP), which all will create a session if none exists. If it's
buried deep enough in a chain of filters it could *appear* to be magic
:-)
There is a method isNew() on the session that you can check to see if
it's a new session that might help in your case.

hi,
I think a new session is created if you invoke an action mapping. this code will not work. what you have to do is, add some attribute to the session.. and check if that attribute is on the session. if not you can redirect to your session timeout page.
Correct me if i am worng in here.
Thanks,
