Hi Peter,
Thanks for the ideas and suggestions. I think the last time I tried I may
have just been impatient with tomcat restarting - it takes quite a while.
Anyway, some progress - I do believe I the mount working, and confirmed
items showing up when doing ls's on both ends. For some reason, though, no
items show up in the collection summary page. They show up when browsing by
author, subject, issue date, etc., but just not by collections.
Any ideas?
Regards,
Charlene
