Are you accessing your webserver as 127.0.0.1? Applets can only make
connections back to the server that they originated from unless they are
signed or given special permissions in the java security property files.
If you are looking for wide distribution, I like have my applet talk to
a servlet that does all of the database access (you can do this over
HTTPS if security is an issue), and then I have the servlet return CSV
or XML formatted data over the HTTPS connection. This kills two birds
-- the servlet can make a DB connection to anywhere it wants, and you
don't have to distribute the postgresql JDBC driver to your clients.
Hope that helps....
