The problem with the private static int reckey variable is that if i stop and
re-start the web server , again i
will be doing the count from 0 ( instead of from where i actually left off from
the previous calls, before stopping the server ).
You are stating that natural order counts cause problems, in the long run. Can
you please elaborate on that. Thankyou.
Cheers,
Amar..

I think this is what you are looking for: synchronize your servlet method...
you may want to create a private static int reckey variable accessible
through a public getRecCounter method (synchronized), rather than using the
natural order count, described. Natural order counts cause problems, in the
long run.
