Tks Richard, but I must have a synchronized func. because each servlet
must know the "current" value of that field before deciding whether update
that field or not. So the point is: is that value reached bound value ???
Maybe when servlet A read that value X, X is under bound value and A
decide to increase X and do some actions with our virtual machine. But, at
the same time, servlet B is reading X and also try to increase X and do some
other actions with our machine. X is not important, but if A and B try to do
many actions in our machine (at the same time), our machine will die ...
That's why I need a synchronized function (or object) between 2 (or
more) servlets to ensure that our simulated machine does not have to receive
many requests at the same time.
Tks for reading my mail
Eric
