When you generate FORMS, you generate on the machine where it is deployed.  If your FORMS application server is a Unix box, the code is generated for that environment. You don't personally code anything in Java, FORMS recognizes that your client is running from a browser and it sends an Oracle-implemented Java applet that renders the user interface, while all the business logic is implemented in PL/SQL and executes on the backend. This same binary can also support typical client/server operation. It is the best of both worlds and you only have to add a tweak here and there. Oracle may provide the ability to write some Java code in triggers that would fire in the applet. For now, trigger events are passed back to the application server.

Hope this helps,
