java "applet not initialized" with ubuntu 8.04 and firefox 3

[kruschev]

I just upgraded to ubuntu 8.04 with firefox 3.0b5, and while most java applets seem to work, when I try to load this one:

http://www.chessgames.com/perl/chessgame?gid=1143795

I am left with a grey box and the message "applet not initialized" in the bar at the bottom of firefox. With ubuntu 7.1 and firefox 2 there was never any problem.

Could someone capable of writing an instruction on how to replace open-java with sun-java and make Firefox use this version instead of just crashing when an applet is loaded?

Please?!

Fought this one long time, and I couldn't get the applets work. Weirdly enough I solved this problem, by uninstalling all icedtea java plugins, and then restarting Firefox and going to the page that was not working. And to my great suprise applet works.

Removing the icedtea worked for me too...thanks

Thanks a lot !!! this worked for me

That worked on Firefox RC 2008060309! Thank you!

Going further, the applet I use doesn't have a verified signature (Gallery2 Upload Applet).
I'm wondering if icedtea isn't capable of running unverified signed code.
Can someone verify this? (It's quite late for me, so I don't have the time to check. I also have to get to uploading 1.7GB of pictures now. (They've accumulated from the past couple of weeks because I couldn't figure this out))

sudo update-alternatives --config java

and select jvm. this way its also easy to switch between jvm's if u have to.

also do

sudo update-alternatives --config javac

and maybe it documentation is available.

sudo update-alternatives --config javadoc

this will work if you have sun-java already installed

in my case I installed sun-java and everything worked fine but then when I installed netbeans suddenly Topcoder applet stopped working, I figured out that netbeans install openjdk as a dependency and sun web start stopped working,
rest normally works and I already told the workaround

removing iced tea worked for me too! Probably best to try that first, then try the other method next.
