How to Reload Applet or Remove class file Caching for Applet

Posted by Pankil Patel on August 26, 2012

Step1: Add below script to your HTML page after End of Body (After </BODY> tag)

<script type=”text/javascript”>
window.APPLET_WRAPER_TAG = “object”;

window.TAG_TYPE = “application/x-java-applet”;

window.currectApplet = true;
window.allAppletsHTML = new Array();
window.allApplets = new Array();


function reloadApplet() {

var resultListObects = getallAppletsHTML();

if (window.currectApplet) {
for (i = 0; i < resultListObects.length; i++) {
window.allAppletsHTML[i] = resultListObects[i].outerHTML;
var htmls = resultListObects[i].outerHTML.split(‘.class’);
htmls[0] = htmls[0] + ‘.class?PankilPatel’;
var html = htmls[0] + htmls[1];
resultListObects[i].outerHTML = html;
window.currectApplet = false;
} else {
for (i = 0; i < resultListObects.length; i++) {
resultListObects[i].outerHTML = window.allAppletsHTML[i];
window.currectApplet = true;
if (!window.currectApplet) {

function getallAppletsHTML() {
var listObects = document
var resultListObects = new Array();
for (i = 0, index = 0; i < listObects.length; i++) {
if (window.APPLET_WRAPER_TAG.toUpperCase() == “APPLET”
|| listObects[i].type == window.TAG_TYPE) {
resultListObects[index] = listObects[i];
return resultListObects;


Step2: Configure value of TAG which is used to display Applet in HTML Page, like object, APPLET or EMBED into first line of script.

Step3: Same way change value of “window.TAG_TYPE” to type given in TAG which is used to display applet, into second line of script.


Now no need to restart your any browser after applet change.

Enjoy your hassle free development of Applet……………….. 🙂


Note: It will work only if you have used only one way to import applet into your HTML file which is any one of  object, APPLET or EMBED.
