You are a victim of Five here and the different semantics of it
compared to zope.app.publisher.

In zope.app.publisher the url for a resource is something like:

<site url>/@@/<name>

where <site url> is basically IAbsoluteURL for zope.site.getSite().

In Zope2 / Five we have:

<context url>/++resource++<name>

instead.

The expression used in page templates to access resources is the same, though.

The reason for this semantic difference is entirely historical. Five
didn't support local component registries / sites at the time when
support for resources have been added. This all happened before those
local registries where simplified in one of the early Zope 3.x
releases.
