Hi ,
I am using tomcat 3.2 not tomcat 4.0 hence as per your suggestion
I did try and implement HttpSessionBindingListener and put the object
into the session in the same jsp ,
the valueBound was called but when the session access threw null pointer
exception valueUnbound was not called
And when I gave a sop the request.getSession(false) printed the same
session object .
I did try with NN and I get the same problem .
Kindly help with your comments

Anyway, first try to localize the problem, there are some ways:
* implement javax.servlet.http.HttpSessionListener interface to see
what's happening with your sessions;
* install RequestDumperFilter filter into your application to see every
request and response data;
* sniff HTTP traffic (don't know how...)
* try another browser (I don't force you to throw IE, just try another
one), for example Mozilla has excellent tool named "Live HTTP headers"
which shows all HTTP request/response headers.
That way you will see if a session invalidates normally for whatever
reason or it "lost" somehow.
