Thanks for your help!

1) I went into Synaptic Package Manager and marked for installation the the files you listed above (sun-java6-bin, sun-java6-jre, sun-java6-fonts, and sun-java6-plugin).
2) Close Synaptic
3) Then I executed your command to remove icedtea (sudo apt-get remove –purge icedtea-gcjwebplugin)
4) Restart firefox

And Done! Thanks for the help!!!!

Teguh,

You shouldn’t have needed to do this. It was already handled by the alternatives system for me:

tyler@baal:~$ ls -la /usr/lib/mozilla/plugins/libjavaplugin.so
lrwxrwxrwx 1 root root 39 2009-04-08 17:12 libjavaplugin.so -> /etc/alternatives/mozilla-javaplugin.so

tyler@baal:~$ ls -la /etc/alternatives/mozilla-javaplugin.so
lrwxrwxrwx 1 root root 49 2009-07-16 10:13 /etc/alternatives/mozilla-javaplugin.so -> /usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so

Just want to add a small “detail” to the awesome explanation by Tyler :
from the terminal type the following :

cd /usr/lib/mozilla/plugins
sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so

in short , the file for Firefox Java plugin is libnpjp2.so.

Tyler …… you are awesome, Thanks for sharing !!!!

Hi Ferran,

The package installs the plugin to /usr/lib/jvm/java-6-sun/jre/lib/amd64/, then uses a postinst script to symlink that into various directories, including /usr/lib/firefox/plugins. If that didn’t happen, something broke the configuration process. Try:

sudo apt-get -f install

And make sure it actually finished installing. If you installed it via dpkg it won’t fix broken dependencies, and will stop before configuring.

Hi !!!

How could you make it work if plugin_6-13-1_amd64.deb is empty?

After installing the 4 packages java is update but firefox fails in open applets because there is not any suitable java plugin in /usr/lib/firefox/plugins.

Can you explain what else you did?

Best,

Ferran
