That depends on whether the helper classes are thread-safe or not. If they
are, then you can instantiate them in init() and reuse them all you want.
If they aren't, then you can't. If the classes need to maintain expensive
resources, it might be worth making them thread-safe if they aren't already.
For more on this, read up on the servlet lifecycle on the web or in the
various servlet books.
