I'm a little confused as to what you're trying to do.  I assume that
getInstance() is a static method in myDBFactory.  When you call it, it
returns an object of type myDBFactory called dbFac.  Is it this dbFac
that you want to use everywhere?  Are you passing a reference to dbFac
to your various stylesheets or what?

If I understand you correctly, perhaps you want to have a "default
instance" of myDBFactory.  In this case, you'd just store the instance
as a static field in myDBFactory and get it with either getInstance() or
a new getDefaultInstance() method.

Not sure what you're trying to do.  If my explanation doesn't help,
perhaps you could explain further and we can go from there.
