Yes, it may be possible and it may work. But just because something
is possible doesn't mean you should do it that way. I don't know why
people insist on ignoring solid advice (with some of the reasoning
behind it provided), just because it sounds complicated (or for
whatever reasons). You're trying to force a square peg into a round
hole. The fact that you have to make it a static method suggests that
it shouldn't really be part of the servlet to begin with.
