Hello, i'm using jre 6 build 104. it seems that I cannot run applets using firefox, but they works perfectly using internet explorer.
(using jre 1.5.0_09 works for both internet explorer and firefox).
with jre 6 instead when I load a page containing an applet I get a red x instead of the applet.

I'm using windows xp sp2. there is a firewall that requires integrated windows authentication.

here is the log in the java console (I've changed the proxy name and address)

The horizontal ticker applet costs $19 to register. Otherwise it will not work. I am NOT going to test your problem because it costs everyone $19.

1. I think you are shilling for money because of all the applets listed from the same source.

2. An applet should run in the browser and not require downloading some zip file to run.

3. If you have a non cost applet and location to test that would be better.

Thanks,

Load the page http://www.appletcollection.com/
Just loading this page doesn't cost anything!
I don't know what site you've tried (sorry I
forgotten to clearly write the url in my post)
I'm only using this applet because of it's
simple to remember url (each time I install a
new java version or browser I use this url to
test applets). I suspect that the problem is
with proxy authentication under firefox, and
it probably will occur with any applet.
If you don't have an http proxy which requires
windows integrated authentication then the applet
will probably work correctly. I know it works
perfectly at home (without proxy).
Thanks.

Thanks Marco,

Loading the default scrolling applet from appletcollection
works fine for me. At the bottom of my FF screen it says
"Applet advnewsscroll7 started". I am using FF 2.0 from
my home.

Thats ok and fine about not specifying the URL clearly
the first time.

I mistakenly tried to use one of the earlier specified
applets that costs something.

Good luck with your applet testing!

I've tested some more applets, and none of them
works with firefox, but they do using internet
explorer. all applet works with firefox if I revert
to jdk 5.0 update 9. this seems a bug to me.
I think that the plugin for firefox doesn't ask
the password for the proxy (see the nulls in the
java console output from previous post).
