Website supports *two* olink databases, identified by
two different parameters:
website.database.document - targets in webpages in your layout.xml
target.database.document - other documents outside of Website
You are setting the parameter for the offsite targets.
That leaves the stylesheet to look for the website
targets in the default location, which is the current
directory. Change the parameter name in your command to
'website.database.document' and it should work.
You only need target.database.document if some of your
webpages contain olink references to documents outside
of your Website.
