Install Oracle Java JRE 7 on Ubuntu with just the command line

Question

• I can't use openjdk because it doesn't have native .jpg support.
• I can't use sudo apt-get install sun-java6-jre sun-java6-plugin any more because apparently those have been pulled.
• JRE version 7 works, but the only way I've found to get it is to accept the terms of service ON THEIR WEBSITE and I need to install Java ON MY SERVER where I only have command line access.

Throw me a fricken bone here Java!

Edit

It just dawned on me that I can download the .tar.gz on my desktop computer and scp it over to the server. Who put me in charge?!

Answer 1

Just download the tarball and then install it. On a Debian or Ubuntu system I would install it to /usr/lib/jvm/XXX and run update-alternatives:

cd /usr/lib/jvm
tar -xzf /path/to/java_tarball.tar.gz
update-alternatives --remove-all java
update-alternatives --remove-all javac
update-alternatives --install /usr/bin/java java /usr/lib/jvm/YOURJAVA/bin/java 1000
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/YOURJAVA/bin/javac 1000

You don't have to run the --remove-all part, in that case make sure the number "1000" is higher than the current one it's set to, which can be found with:

update-alternatives --display java (or javac)

Answer 2

An easy way to install the Oracle JDK and the Oracle JRE and receive software updates of those packages is by add a repository with installation packages to our system with those instructions:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo update-java-alternatives --set java-8-oracle

Answer 3

Actually it is possible to accept license and download the tar from command line, all in one step.

You can pass a cookie to the server via wget in this way:

wget --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u51-b16/jdk-8u51-linux-i586.tar.gz

After that you can just install the tar by extracting and updating alternatives as in @aseq answer above.

Note: Make sure that accepting the license in this way is legal, before using this method.

Note: Name of cookie and its value might change in time.
