In the old days sun-java6-jre was common. These days Oracle has pretty much killed off all of the old Sun software. So these days it is simply OpenJDK packages. Which you know because you were installing them. > aptitude install openjdk-7-jre That should have been enough. What about it wasn't enough for you? > ln -s /etc/alternatives/mozilla-javaplugin.so > mozilla-javaplugin.so This creates a zero sized file mozilla-javaplugin.so due to the shell redirection that happens before the ln command starts and then the ln command symlinks mozilla-javaplugin.so to the current directory, which happens to be on top of the newly created file. If that was in a wiki anywhere please delete it. It is completely bogus. Fortunately you were in your home directory and so instead of doing anything really bad it just left junk behind. You might want to remove the files to clean up. The expected syntax would be: ln -s /etc/alternatives/mozilla-javaplugin.so mozilla-javaplugin.so Or: ln -s /etc/alternatives/mozilla-javaplugin.so . > Now I want to uninstall Java and undo all settings > to go were I was before all this got started.

Simply purge all of the packages you installed. > aptitude install openjdk-7-jre > aptitude install openjdk-7-jre-lib > aptitude install icedtea-7-plugin > aptitude uninstall openjdk-7-jre > aptitude purge openjdk-7-jre > aptitude install openjdk-7-jre-lib icedtea-7-plugin For the above simply purge those. I use apt-get but aptitude is fine. dpkg -l | grep openjdk What does that show? Purge all of them. aptitude purge openjdk-7-jre openjdk-7-jre-lib icedtea-7-plugin That will take care of all of the package alternatives. If you created any additional files or symlinks you will need to remove those manually. It was hard to follow your history. > cd /etc/alternatives > ln -s /usr/lib/jvm/java-7-openjdk-i386/jre/lib/i386/IcedTeaPlugin.so >& mozilla-javaplugin.so rm /etc/alternatives/IcedTeaPlugin.so rm /etc/alternatives/mozilla-javaplugin.so > cd /usr/lib/mozilla/plugins/ > ln -s /etc/alternatives/mozilla-javaplugin.so > mozilla-javaplugin.so > ln -s /etc/alternatives/mozilla-javaplugin.so mozilla-javaplugin.so rm /usr/lib/mozilla/plugins/mozilla-javaplugin.so You may want to clean up anything left behind manually. find /etc -name '*java*' Good luck!
