Hi Brian, 

I know what's wrong. We've changed the database model a bit in 1.1 (we've added a comment field) so as you're using 1.0 the XWikiDocument class doesn't have the getter/setter for comments.

+        <property name="comment" type="string">

+            <column name="XWD_COMMENT" length="1023" not-null="true" />

+        </property>

I've uploaded a fixed HBM file on 

http://www.xwiki.org/xwiki/bin/view/AdminGuide/InstallationDerby

Sorry about that

-Vincent

This is using XWiki 1.0.

Did you encounter this along the way?

Brian.

FWIW I've succeeded in running XWiki on Derby and I have created this page to document it:
