It looks like I failed to get the actual RC1 API release when I built the 
QuickStart. This means that the Grouper API in the QuickStart wasn't quite 
as blair intended - which may explain your problems with GSH?

The QuickStart which was distributed should have been internally consistent 
- HibernateDAO was in the same package as GrouperHelper - and so should 
(and did for me) compile. On the other hand if you tried to run the UI code 
against the official RC1 API package it would fail as you have reported.

I've made a new QuickStart package which I will pass on to Tom to put on 
the Wiki.

You can do this using Xml import. I've attached a sample XML file which you 
can load using:

ant -Dcmd="GrouperSystem <PATH>/wheel.xml" xml-import

blair is working on allowing new API versions to work with old databases. 
It isn't clear if this will be part of the 1.2 official release yet. 
Otherwise exporting the database as XML and importing it into a clean 
database should preserve your data.
