Its the Java security manager. By default, this will only allow an applet
to connect to its web server. You must either run postgres on the same
machine as the web server or edit the jre/lib/security/java.policy file on
your client PC to allow the applet to connect to your postgres machine.
There are ecellent tutorials on applets and security on Sun's Java web
site (http://java.sun.com).
