We have done a similar thing with filter. You put a check in the filter to redirect to an error page if the session is not present in the request. this will also prevent a user to access the site without login in.
Filters however is only available with servlet 2.3

You can store an attribute in session when you initially start the session
Subsquent checks for that attribute on EACH request will check if that
Attribute doesn't exist...session has expired or they are not logged on etc.
Of course the key to this is to put a hook on RequestProcessor to run this
snipt
For each request...if you do this correctly...the request won't even make it
to your action
You can redirect them to whatever page you like...
We have similar code but we use Struts 1.0 so we have extended ActionServlet
and have
Written the processPreProcess() (I think..that is what the method is
called..can't recall the actual name)

Subject: detecting session timeout
Any suggestions on how to detect
session timeouts? I am experimenting
with extending TilesRequestProcessor
(I'm using struts 1.1 and tiles). Here's
an example of the kind of thing I would
like to detect: I have a multipage registration
process. Suppose a user gets halfway through
and then goes away for some reason (lunch?).
They come back and their session has timed
out. This means that the data that was gathered
and placed in the session on previous forms is
gone. The validator framework then complains
about missing data from the previous pages. I
just want to put up a special page indicating that
they took too long to register. I need this same
basic session in a number of places, so I really
need a general solution. Any ideas?
