Applet issues

Shades · **Posted:** Fri May 30, 2008 5:44 pm

My applet itself runs when run through NetBeans, although when incorporated into it's html code, either the applet doesn't load (showing the applet window with an X) or loads (this is when I run the auto-generated NetBeans html code) but doesn't do what it's supposed to: it creates the progress bars and the button and everything, but does not download the files or show progress. So, is this an issue with my applet's structure or is it a case of me overseeing certain necessary commands?

code:

import java.net.*;
import java.io.*;
import java.awt.event.*;
public class dlProgressBar extends javax.swing.JApplet {
static int runCount1=0, runcount2=0, runcount3=0;
static String links[]={"http://mirror.silliam.com/dota/DotA%20Allstars%20v6.52c.w3x", "http://dota.ws/download/DotA%20Allstars%20v6.52c.w3x", "http://www.myklspace.com/dota/DotA%20Allstars%20v6.48b.w3x"};

/** Initializes the applet dlProgressBar */
