I’m trying to use Java Applet for my website.
but I have a problem with refresh java applet content.

here is my code, (AppletTest.java)

import java.applet.*;
import java.awt.*;


public class AppletTest extends Applet{

    public void init(){

    }

    public void stop(){

    }

    public void paint(Graphics g){
        g.drawString("ABC",20,20); //I will draw DEF and FFF after ABC.
    }

}

and HTML is (appletTest.html)

 <body>
  <applet code="AppletTest.class" name='AppletTest' width='500' height='300' style='border:1px solid #cdcdcdl'>
    <param name='cache_option' value='no'> // I put this code to avoid browser remember applet but it does not work. :(
  </applet>
 </body>

Firstly I draw ‘ABC’ and It draw well.

and I change ‘ABC’ to ‘DEF’ and compile again and run it.

it draw ‘DEF’ well. And I change ‘DEF’ to ‘FFF’ and compile and run.

but it does not change to ‘FFF’. it still ‘DEF’. I refresh the page many time but it is not changed.

I think my browser remember pre applet content. so to avoid it, I put the <param name='cache_option' value='no'> code into applet tag. but it does not work…

anybody know this, please advice me.

Thank you!

    Applets should be tested in tools like applet viewer or Appleteer, which do not cache classes. If testing in a browser, ensure the Java Console is open (there is an option in the Java Control Panel) & type Ctrl-X (I think that is ‘clear class cache’) before refreshing the page.

    I put the <param name='cache_option' value='no'> code into applet tag..

    That only works with recent JREs. What JRE version has the user got installed?
