Hi,
Thanks for your response, Craig McClanahan, and Dmoss.
If this is the case, does it mean that I cannot cache session data ? Then how
do I store my session data?
Is it by the way of writing data into hard disk as files?
May be I am bit confused , pls give your opinions.
thanks in advance.

The only limit is the overall heap size allocated to the JVM that is running the
servlet engine -- there is no limit on any individual session object (this is
true
of *all* objects in Java).
Most JVMs default to a fairly small maximum heap size (16 megs or 32 megs), but
offer a command line option or something to change the limit. Check the JWS
docs
for how to do it there.
