Oracle11g Forms run by Java Web Start

Most of the 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 for Java Web Start. It would be quite difficult to run Oracle Applet Based Forms in modern Web Browsers. It would be little bit tricky but best solution for Oracle developer to run Oracle Forms as a separate application. For the days it's very stable and reliable.
