Re: jdbc connection refused, please help - Mailing list pgsql-general

You have fallen fowl of applet security. Here, you can only connect to the
same server as the applet was downloaded from, so unless you connected
directly to 127.0.0.1 to download the applet it will fail.

The rule is: The URL for the applet must be identical to the jdbc url.
Pseudonyms, or identical IP addresses won't work. The URL's must match
exactly.
