I mean populating a vector on the server side and keeping that in
sessionContext , so I reload from the vector and not the database. Will that
be a possible solution? What are the down sides?

I am not very sure abt the performace of applets? Will that add may
overheads to the system? I would like to try the option.. Can you guide me
on this please?

I was thinking on lines of parsing the XML from the JSP... just so that I
can populate from the XML rather than the database. Will it not be faster to
parse from a formatted XML doc than the database?
