Install Java 1.6 in Debian (i86) , enable firefox 3.6.x Java Plug-In

Step1: Add sid repository in /etc/apt/sources.list

       ##sid
# deb http://ftp.de.debian.org/debian/ sid main
# deb-src http://ftp.de.debian.org/debian/ sid main

Step2: Update and install Java (as root)

apt-get update

apt-get install sun-java6-jre sun-java6-bin

update-alternatives --auto java

java -version (should print the version available)

(Note: Now you should disable sid repository as they are not stable , an 
update or some package install may broke your system )

Ok, also in the repository of Debian you will find sun-java6-plugin , but 
you may not want to install that cause it will also install the iceweasel 
(the default browser)
If you run firefox the latest version you could just link the 
/usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so to 
/usr/lib/mozilla/plugins (if that is the path where firefox will search 
for installed plugins)

ln -s /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so 
/usr/lib/mozilla/plugins/libjavaplugin.so

Open firefox && type about:plug-ins 
It should print all the plug-ins installed
