Install Oracle JDK in Ubuntu

Installing a new JDK with proper update-alternatives setup

This example uses jdk1.6 update 27. Adjust as needed.

Download the self-installing package from Oracle, and go to /usr/lib/jvm and run it. It will unpack the entire jdk in ./jdk1.6.0_27

Rename the directory to "java-6-sun-1.6.0.27", and create a link to it named "java-6-sun":

mv jdk1.6.0_27 java-6-sun-1.6.0.27
ln -s java-6-sun-1.6.0.27 java-6-sun

Create a new text file .java-6-sun-1.6.0.27.jinfo (note the initial period!) with the following contents:

name=java-6-sun-1.6.0.27
alias=java-6-sun
priority=63
section=non-free

Install the new jdk/jre binaries as proper "alternatives":

egrep "^(jre|jdk)" .java-6-sun-1.6.0.27.jinfo | while read mode name link; do
  update-alternatives --install /usr/bin/$name $name $link 5
done

Use the update-java-alternatives convenience script to switch:

update-java-alternatives -s java-6-sun-1.6.0.27
