Hi Ravi,
Browsers and servlets live on separate machines so there is no way a servlet
can do what you
want it to do. Signed applets could do this but this has its own problems.
Much better to save
the data on the server in such a way that a user can retrieve it easily.
This is the only way
if the data is of any significant length.
There is a way that has been approved though. That is cookies. You can
create and send cookies
to the client browser which can store this data for you. This is only
practical for small amounts of data though.
Direct server to client harddrive access is a no no!
There is a very good reason for this to happen, evil, nasty, stupid people
sometimes try and stick
malevolent software on client machines via the web and for this reason
Browser security has been
increased in order to prevent this very thing from happening.
Hope this ramble helps
Andy Bailey
