Subject Re: Derby Config Question
Date Mon, 20 Mar 2006 17:28:23 GMT
Hi Philippe,

I think this should work.
In your case the application is loading and setting all the Derby system 
properties, whereas
following the Derby documentation way - pointing the derby.system.home 
to the derby.properties, Derby would
have done it for you.
