Subject RE: Problems to use Derby Network Server
Date Wed, 05 May 2010 03:15:54 GMT
Hello Fabricio,


I’ve normally seen a “Connection Refused: connect” message when a firewall
is blocking a network port (Windows Firewall most likely). You can add an
exception to the firewall on the server ( for port 1527.
Alternately, you can try disabling the firewall briefly to confirm that with
the firewall turned off you can connect to the derby network server. 


FYI. you will normally see a “Connection Timeout” message when either the
destination (server) IP address is wrong, or the network server has not


Best regards,


Thomas Taylor
