In our application, we have around 3-4 servlets based upon the broad
functionalities of the system.
What we want to know is that how do we share common information between
these servlets. Can we have something global across servlets. Or can we
access variables of one servlet in some other servlet.
What is the usual way of doing this. Any pointers to some working examples
on servlet designing etc. will also be appreciated.
TIA and Rgds,
Kaustubh
