With a connection refused error, I would look at the following: 1) Does the port number in the *-ds.xml file match what the database is listening on? 2) Is the database listening on the port I think it is listening on? (Use tcpview or netstat to determine the port that the database has open.) 3) Is there a firewall blocking access to that port? 4) Can I telnet to the database port from the remote host? 5) Can I access the database via JDBC when I run on the same host as the database?
