You have a few options (some of which really suck),

1. You can require that all your extranet members use SQL*Net compiant firewalls.
2. You can wait until Oracle provides middleware to tunnel through some other protocol (preferably HTTP, or you'll probably have problems with proxies too).
3. You can buy middleware that already tunnels through HTTP.
4. You can write your applets without JDBC and pass the data to your applets using RMI, CORBA, or some other firewall-compatible method. I personally use Servlets to connect to Java applets and pass all my data back and forth using HTTP.
