Could not listen on port 1527 on host localhost.

Answer 1

Possibly you already have another application (perhaps another JavaDB instance?) listening on port 1527 - that could explain the "could not listen" message. Use netstat to check.

Answer 2

Hi,

I think that UnknownHostException is related that intracare can't be resolved to an IP.

I would:

1. Ping that host.
2. Check C:\WINDOWS\system32\drivers\etc\hosts or /etc/hosts files.

Regards.

Answer 3

Check the DNS settings on the host. Your short names do not resolve correctly.

Answer 4

Mayby string you are typing as a host name is wrong? Maybe it is firewall problem?
