Java Player/Applet

Hi Guys. I am trying to get an applet to play a mpeg file through an html page and I have it setup like below. Every time I run it, it gives an error saying that Applet PlayerApplet notinited. I'm sure i'm doing something wrong.
Please help (Btw - the video clip is called mmvcd.mpeg and all these files/html/class etc are on my desktop)

If another approach is better to make this play thats cool too. Just need something ultra simple.
Thanks kindly

The html page says:
<HEAD><TITLE>Test Program</TITLE></HEAD>

<APPLET CODE=PlayerApplet
<PARAM NAME=FILE VALUE="mmvcd.mpeg">


The Java Code Says:
import java.applet.*;
import java.awt.*;
import java.net.*;
import javax.media.*;

public class PlayerApplet extends Applet implements ControllerListener {
   Player player = null;
   public void init() {
      setLayout(new BorderLayout());
      String mediaFile = getParameter("FILE");
      try {
         URL mediaURL = new URL(getDocumentBase(), mediaFile);
         player = Manager.createPlayer(mediaURL);
      catch (Exception e) {
         System.err.println("Got exception "+e);
   public void start() {
   public void stop() {
   public void destroy() {
   public synchronized void controllerUpdate(ControllerEvent event) {
      if (event instanceof RealizeCompleteEvent) {
         Component comp;
         if ((comp = player.getVisualComponent()) != null)
            add ("Center", comp);
         if ((comp = player.getControlPanelComponent()) != null)
            add ("South", comp);

I don't believe you can just use the javax.media classes in an applet

AFAIK, Java does not ordinarily support mpeg. See http://www.alphaworks.ibm.com/tech/mpeg-4

CEHJ - i'm even trying .mov files and .wmv files and I keep getting this error saying Applet PlayerApplet "notinited"

I check the plug-in settings for Java Plug-in too and they seem to be ok for my browser (IE)

Have a look for exceptions in the plugin console

CEHJ where is this plug-in console you are referring to?

I did go into IE options and started using the Microsoft VM and now the error doesn't come up any more
It just says done and no video.

>>CEHJ where is this plug-in console you are referring to?

That varies depending on what browser version you're using. The following may help:

Is the plugin set as the default VM for your browser? and do you have JMF installed?

ie. you need both

(and jmf does support mpeg)

Objects - i have installed JMF yes, and fixed the classpath to point to the jmf and sound jar files

The default VM for my browser - I tried using both the MS version and the JAVA one. When i have the MS version enabled, the error Applet PlayerApplet "notinited"
 goes away from IE - and it just says Done. When i turn it on for IE - it gives me the same error

I even downloaded Netscape 7.2 and it also gives me that error Applet PlayerApplet "notinited".

CEHJ - here is the ouput from the console after I open my web page and i get the error (using Sun Java JVM) - if I use MS VM then no output in console - but no video in applet either.

looks like jmf is not installed on the client correctly
i'd suggest copying the jars to the jre's 'ext' directory (<jre>/lib/ext)
