The client interface is provided through HTML for the Self-Service interface, and a
Java applet for the professional, forms-based interface using a Java-enabledWeb .The Desktop Tier Oracle Applications Architecture browser. The desktop client with Oracle JInitiator downloads the applet on demand
and the applet is cached locally for future use.
The Forms client applet is a general-purpose presentation applet that supports all
Oracle Applications Forms-based products, including those with customizations
and extensions. The Forms client applet is packaged as Java archive (JAR) files.
The JAR files contain all Java classes required to run the presentation layer of Oracle

The Forms client applet and commonly used JAR files are downloaded from the
Web server at the beginning of the client’s first session.
