"no filer" error

I've installed xindice-1.1 on an Ubuntu 8.10 (Intrepid) system running it's stock
tomcat6 by putting the war file, named xinice.war, into tomcat's webapps directory.
I also installed the addressbook application, with the mods described in this forum's
thread "re: install xindice into tomcat6.0" by Natalia Shilenkova.

When I browse to http://andy:8888/db, I get the "ugly debug tool" and can 
navigate to db/system/SysConfig, etc. without error.

However, I get the following error whenever I try to use the command line tool:
/usr/local/java/xml-xindice-1.1/bin$ ./xindice li -c xmldb:xindice://andy:8888/db
trying to register database
XMLDB Exception 1: org.apache.xmlrpc.XmlRpcException: Collection 'db' cannot store resources (no filer)

I can browse to http://andy:8888/addressbook, and I see the application, but when I
try the "List Contacts" link, I get "An ERROR has occured!!!" with no additional
information. Likewise when I try to add a contact.

The tomcat logs have no xindice-related information, other than frequent entries 
like the following in the catalina log: 
Dec 7, 2008 8:36:06 PM org.apache.xindice.core.DatabaseChangeObserver$FlushTask run
INFO: Successfully flushed 0 collections out of 0

The first step here is to get some useful loggin going here, but I can't figure out
how to configure it.

Any advice on how to proceed would be greatly appreciated!
