Introduction

Oracle Forms does not run in the browser but as an applet using a Java Runtime Engine plug-in. Previously this was the JInitiator, but this is now de-supported in favor of the Sun JRE. See the following notes for more information on this:

<Note 393931.1> Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12
<Note 290807.1> Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite 11i

To run the Forms applet a number of JAR files are downloaded to the client. These JAR files deliver the classes required to render the UI, process the actions performed by the user and communicate with the Forms Runtime process (R11i = f60webmx / R12 = frmweb) on the Application Tier server.

The JAR files are stored on the Application Tier server ($OA_JAVA/oracle/apps/fnd/jar)and normally only changed after patch delivered new classes and adadmin was used to regenerate the product JAR files. Since these JAR files do not change regular and in total are about 10Mb in size it will be useful to 'cache' the files on the client PC to improve start-up time of the Forms applet and decrease network load.
