Explanation:
Note: ORACLE APPLICATION SERVER FORMS SERVICES – ARCHITECTURE
The OracleAS Forms Services consists of three components: a Forms Client that is
downloaded automatically to the end user’s browser and cached, the Forms
Listener Servlet, and the Forms Runtime – on the middle tier.
Forms Client (Java Applet)
When a user runs a Forms session, the Forms Client – a thin 100 percent Java
Applet – dynamically downloads from the Oracle Application Server. This generic
Java Applet provides the user interface for the associated Forms Runtime process

on the middle tier, and handles user interaction and visual feedback such as that
generated by navigating between items or checking a checkbox. The same Java
applet is used for any Forms application, therefore it is downloaded only once and
cached on the client and so is available for subsequent Forms applications
