Hi Walter, Yes this is expected - if you don't define and connect with a specific username, the default is 'APP' as the schema and owner name for that database.
More info in the developer guide in the security section: http://db.apache.org/derby/docs/10.4/devguide/ I was asking if you had set-up particular permissions or not as you mentioned your connection from OpenOffice was read-only - how did you notice and verify this? Can't you update data at all? Cheers --francois On Sun, Feb 22, 2009 at 2:11 AM, Walter Rogura <[email protected]> wrote: > Hi Francois, > > I even didn't set up any users for the db.
