I've been pulling my hair out trying to get Oracle Java running in Chromium. My Java version is shown below:

java version "1.6.0_32"
Java(TM) SE Runtime Environment (build 1.6.0_32-b05)
Java HotSpot(TM) Server VM (build 20.7-b02, mixed mode)

In my bash_profile I have:

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_32 
export PATH=$PATH:$JAVA_HOME/bin 4

I've tried linking as below:

ln -s $JAVA_HOME/jre/lib/i386/libnpjp2.so /usr/lib/chromium-browser/plugins

I had it working and then upgraded to 12.04, and am now stuck.

I used to link the libnpjp2.so as /usr/lib/mozilla/plugins/libnpjp2.so and ~/.mozilla/plugins/

EDIT: Where to download and how to install the sun java plugin

  • No difference. I tried starting with --enable-plugins also, but still no sigh of Java in about:plugins. – Tom Eustace Jun 12 '12 at 13:35
  • I'd be happy if I could get it working in Firefox either. – Tom Eustace Jun 12 '12 at 13:50
  • @TomEustace : I added the link from where I found the detailled explanations to install sun java plugin. – Cédric Julien Jun 12 '12 at 13:57
  • ok, I had the plugin enabled for jre 1.7.04 in chromium by following the instructions. I now just need to get it working for jre 1.6.32 as that is what I require. jre 1.7.04 was located in /opt/java/64. I am using a 64 bit system but require 32 bit jre. – Tom Eustace Jun 12 '12 at 15:55
  • I have purged openjdk. I now have only oracle jdk 1.6.32 installed. I run the various commands to link to Java plugin but still not working. Java is installed at /usr/lib/jvm/jdk1.6.0_32. I've updated alternatives to point to this version. I must be missing something!! – Tom Eustace Jun 12 '12 at 21:31
  • @TomEustace : your problems seems related to a 32/64 bit problem, I'm not sure a 64bits chromium could load a 32 bit java plugin... Try to install ia32-libs to allow the compatiblity 64/32 bits – Cédric Julien Jun 13 '12 at 08:17
  • Appreciate the help, but unfortunately no change after installing ia32-libs. – Tom Eustace Jun 13 '12 at 21:12

I finally got it working by running the commands from this link for amd64

sudo apt-get remove firefox openjdk-6-jdk icedtea-6-plugin
sudo apt-get install firefox:i386 openjdk-6-jdk:i386 icedtea-6-plugin:i386
