Oracle Jinitiator a brief introduction

Hereafter referred to as Jinit, it is a JVM distributed by Oracle Corporation. Jinit enables the Oracle Forms client application (otherwise known as Oracle D2K in earlier versions) in a web browser.
Earlier the Oracle forms where only available as client installed stand-alone applications which accesses the database and file system to run the application. With the advent of Jinit, the client installation of Oracle Forms run time is not required. The browser plug in for Jinit only must be installed.
While accessing the application for the first time if the plug in is not installed the browser will prompt for the installation. At this point, you must be logged in with Admin rights. You can revert the rights once the installation is done.
The Jinit referred to in this article is which was rolled on August 2007. The versions is based on some practises. The first two numbers that is 1.3 in our case refers to the Sun Microsystem's JDK version 1.3 or later.
Installing Jinit
Once the URL for the application is configured, use this URL from a supported browser. The browser should prompt for installation of the Jinit plug in. If the browser is not prompting for the installation, then most probably there is problems with configuration. Sometimes the browser may block the plug ins to be installed. Check for the information bar which appears in the browser. Also check the settings for installation of plug ins in your browser.
Once the browser prompts for the installation, Install it. Just install with no changes as prompted by Oracle. Once the installation is complete, the application should open in the browser window. Though there are problems with Windows XP, with Internet Explorer the application may not open in the same browser window. Close the browser window and access the application URL once again. If the installation is properly done, the application should open.
Problems with Jinit
Jinit is known not to work with Windows Vista. There is no plans for Sun to support JDK 1.3 on Vista. So Oracle has not certified Jinit for Vista. Vista users should consider using Sun's plug in 1.5.0_06 or 1.6.0_04. This will work for Internet Explorer as well as FireFox browsers.
Can I run Jinit In Linux?
Jinit is not only certified for Microsoft Windows platform. Other operating systems must use the Sun's plug in for accessing Oracle forms application through browsers.

For accessing Oracle Forms application from inside Linux operating system, Oracle certifies the usage of Sun plug in for Mozilla 1.5 browser. Use plug in 1.4.2_06 for Mozilla 1.5
What is it's future of Jinit?
The future of Jinit is not bright (thanks to Oracle), it is being replaced by the Sun's JDK 1.5/1.6 in 11g. But it is just a rumour, not a confirmed news.
