Well it depends, if the hibernate filter should be activated at the
same url's as wicket.
I've never had a case where my wicket filter and osiw did not match.
You might have performance increases if they differ, for example if
you know that you willl never use hibernate on /myapp/ but always put
in /myapp/pages/dynamic/* for pages that use db lookup..
