How to close java Applet through code

Question

I am developing a java applet. I want it to be closed by the code. I have used System.Exit(0) but it is not working. Is there any other method to achieve this?

Answer 1

applet.getAppletContext().showDocument("ThanksForUsingOurApplet.html");

As to the comment that a signed applet can call System.exit(n).

It can in some browser/JRE combos., it can't in others. In the ones that it can, it shouldn't since an applet may share a VM with other applets (less common these days), and even if not, it is the user's responsibility to close an applet by closing the page.

An applet is a guest in a web page. Calling System.exit(n) is like burning down the guest house.

Answer 2

As said above,exiting applet is simple by adding System.exit(0) in if(condition) for which you want to close the applet.Though I am describing of applet viewer.But,it certainly works fine.

Answer 3

An applet cannot call System.exit(int);. Security permissions don't let an applet do this. And if you are trying to close the browser window, even if you signed the code and the browser/user trusted you, the browser wouldn't let you shutdown/close the browser window.

If all you want to do is close a Window/Frame created from the applet, this is no different than closing a window outside of an applet.

Answer 4

Try to remove java applet code by javascript. Example your html:

<button onclick="clickButton()">Click me</button>
<div id="appletCode">
     <applet width="200" height="200" archive="ImageIconApplet.jar"
        code="com.whitefang34.ImageIconApplet" name="test"/> 
</div>

your javascript code:

function clickButton(){
     var SS = document.getElementById("appletCode");
    SS.innerHTML = "";
}
