Hi there,
Thanks Brevsville Administrator for your views. However, two doubts still remain
unsolved. I repeat them here again:
* Second problem relates to session time-out. We have not changed the session
time-out interval (i.e. the time out is 30 mins, by default). However, if user
is inactive for some time (< 30 mins), *some times*, it throws the user out of
session. What could be the reason behind such inconsistent behavior? Should we
explicitly set the time-out interval? Is there any other way to void it?
* I have read somewhere that we should not use Web Server for deployment of our
web applications, and instead use an application server, that has a Web Server
in it. Is it really so? How it affects the application, in terms of performance
and otherwise?
We are using JWS 2.0 with JDK 1.2.2 (not JDK 1.1.7) for Windows NT 4.0 Server
(SP 5) with SQL Server 7 as database.
Hope to get your views.
