Live Sport Commentator Java applet which is available at
http://sport.onet.pl/live.html (only some of the events are commented) fails to
load in Mozilla.

Reproducible: Always

Steps to Reproduce:
1. Open http://sport.onet.pl/live.html


Actual Results:  
Applet fails to load

Expected Results:  
We want to listen.. ;) - spoken on behalf of Sport Fans.

Errors from the Console:

load: class onet.komentator.Komentator2.class not found.

java.lang.ClassNotFoundException: java.io.FileNotFoundException:
http://sport.onet.pl/onet/komentator/Komentator2/class.class

   at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)

   at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown
Source)

 Comments from our dev team member, Gabriel:

Please look at: 

1) how code attribute is passed:

<applet code=onet.komentator.Komentator2.class height=1 name=TestClient width=1
MAYSCRIPT>

 Should be either class name: onet.komentator.Komentator2 or
 Path to it: onet/komentator/Komentator2.class

2) They also use: 

<param NAME="useslibrarycodebase" VALUE="komentator.cab">  - not sure if and to
which extent Java handles .cab files.

Confirming and accepting.

Yes, I believe it's one of the reasons you gave (or both). Will investigate.

Comment 2

[Jacek Piskozub]

The result of my investigation: 

The site uses Microsoft model of signing a Java applet. The signing is necessary
if the applet is supposed to leave the Java "sandbox" but signed cab files
should be served only to IE browsers. Mozilla (and other browsers using Sun Java
plugin) should be served a jar file signed using the Sun signing model.

For Sun documentation on signing Jar files, see

The same problems occur with chats on onet.pl.
They are still using soon-to-be-illegal Microsoft Java...

Comment 8

[Zibi Braniecki [:zbraniecki][:gandalf]]

At the moment instead of trying to load MS Java, that site gives Mozilla's user
info:

"Attention!
Microsoft Internet Explorer ver. 5.0 or better
is needed for proper work of this service. Sorry."

Jacek: basing on success with bug 219953, meaby it's time for another letter?

FIXED according to http://osiolki.net/poprawiony/liveonet (Osiolki.net is a
Polish web standards evangelism team, consisting of Mozilla, Opera and
Konqueror/Safari users)

The applet now loads properly in Sun Java VM and is said to work ok in Firefox
and Opera. It would be nice to check it during real transmissions.

They're still saying that "it works best with IE and MS JVM", though.
