Oracle11g Forms run by Java Web Start

Most of modern Web Browsers relays on HTML5. Due to the security reason they obsoleted Adobe Flash Player, Silver Light and Java Applet too. Most recently Oracle announce not to support(End of Life) Java Applet using Web Browser, where they will remain support using Java Web Start. It would be quite difficult to run Oracle Applet Base Forms in modern Web Browsers. Little bit tricky, has some tactics and best solution to run Oracle Forms as a separate application. For the days it's very stable and reliable.
