Re: Connection pool problem

I finally get it to work. The problem doesn't come from
jdbc nor dbcp, it's because i use cygwin to connect to gnome
on the linux box. It seems that there are conflict between cygwyn ports
and jdbc ports
Don't have a real explanation but if cygwin not running everything works
in jdbc & dbcp
Bye
