Marcos,
You need to make the piece of code thread-save...so that the servletthread
cannot be interrrupted between the read, ++ and the write code.

Subject: sharing i/o file
hi,
i have running a sevlets that reads from a file a number and it adds
one more. after changes it saves.
i want to use the same file from another servlet. any problem?? if
both servlets try to open and save at the same time.
file = 4455
servlet 1 servlet2
{ {
read from file 4455 read from file 4455
++ ++
4456 4456
save save
} }
it is wrong. in file should be 4457.
thanks in advance,
marcos
