Hi all ,
Can any body provide some information for the following situation ?
Since JSP page is compiled into the servlet class that has only one
instance(normally) and initilized only once. All the variables declared
using %! % tags become the part of the member variables of the servlet

Hi,
what is the best way to do session validation? If a session times out, all

Hi, Craig,
Can you estimate how long a session should last to be useful. I think in

I'm getting the following error when trying to use taglibs with
tomcat3.0 and jdk1.2.2 - has anyone got taglibs to work with this
configuration? Or maybe it's a bug with tomcat?
Unhandled error! You might want to consider having an error page to
report such
errors more gracefully
Another one to look at is Resin1.1
It is currently in beta, but I use it to develop and it seems rock solid.
It is fast, small and comes with a mini-http server as well as the ability
to plugin to IIS, Apache etc. Check it out at www.caucho.com

Bill, your code below works great, but it's too much code in an html

which i use pretty much thru my entire site.

Hi !
I have been following the discussion about session management ( amongst
others ) and I just thought about something : if I understand correctly, one
can implement session management through URL rewritting which, in a word,
does nothing more than adding the session ID to the URL in the form

Oracle calls classes111.zip the jdbc driver file for Oracle 8.0

This seems similar to a problem that I had when everything seemed to be initialized on

to set the timeout to -1 (never) or

That was my point, where else could you store his key, other than in the
