static should have nothing to do with this. static just controls
whether something is a class variable/method or an instance
variable/method. (If you don't understand the difference, you should
get a basic Java book.)

There's lots of information missing here. Like what is db? What do
its methods do? How is assignNum called? And do you have your
servlet implementing SingleThreadModel? There may be other relevant
considerations as well.
