Subject Re: Hanging around derby.log, how to center it?
Date Tue, 06 Apr 2010 16:33:23 GMT
I connect to the database via :

final Connection con =
DriverManager.getConnection("jdbc:derby:db.sqlwrapper;create=" +
return con;

and I'm not sure whether the Driver is already loaded and not.
Controlling that is wanting to pain oneself.

I'd rather disable this derby.log all together, in the user
environment. Although this means missing precious logging. I'd highly
recommend an easier solution.
