OK, so "The connection attempt failed" exception was thrown by ...

....

the Java networking stack because of communication problems with a SOCKS
proxy server.

Maybe your environment is different, so you're not using the proxy in
netbeans and the proxy is broken?

Does `psql' work?

Thanks Craig for the tips, the proxy is working, also configured in netbeans.
The psql is working too, but i'm getting the same message every time. I
managed to develop another aplication in which i use hibernate and
webservices and all seams to be working quite good, but in the other hand i
can't put toghether a simple desktop aplication... is quite depressing...

Any comments are accepted..

Tks in advance
