Re: Connection Problem - Mailing list pgsql-jdbc

Hi Radek,

Output from those commands attached.

I always completely shutdown my laptop and pull the plug. So, it is
doing a complete cold boot each time.

When I try connecting to the database with ExecuteQuery, the same error
is returned for both "localhost" and 127.0.0.1, when entering those
values as the "host" on the connection dialogue.

Via a browser, if I access http://localhost it returns the "It Work's!"
output from apache.

Thanks to everybody for your help.

Cheers,
Rob
