 How to install Oracle JDK on Linux Mint


Unlinke JRE, Java Development Kit includes various development tools like the Java source compilers, bundling and deployment tools, debuggers, development libraries, etc.

Tutorial about How to install JRE for Linux Mint is almost identical for JDK.

Mint comes with a OpenJDK version of java libraries, which shouldn't be used for example Android development. [1]


1. Open up the Terminal (Alt + F2 > Terminal).

2. Remove OpenJDK installation.

sudo apt-get update && apt-get remove openjdk*

3. Download Oracle JDK from here. You are looking for a linux version with tar.gz extension. Also choose the right version from 32-bit (x86)  and 64bit (x64) one.

4. Change directory into one with downloaded tarball. In my case $HOME/Downloads.

cd ~/Downloads

5. Extract tarball. Replace with a name of dowloaded file. (just press Tab and it will be autocompleted.)

tar -zxvf jdk-

6. As a root create a folder in /opt where jdk will be stored.

sudo mkdir -p /opt/java

7. Move extracted folder to /opt/java. In my case, version number was 1.7.0_25.

sudo mv jdk1.7.0_25 /opt/java

8. Make JDK system default.

sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.7.0_25/bin/java" 1
sudo update-alternatives --set java /opt/java/jdk1.7.0_25/bin/java


9. Test installed java version.

$ java -version
java version "1.7.0_25" Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

Optinaly install firefox plugin by linking libnpjp2.so file to ~/.mozzila/plugins folder.

mkdir -p ~/.mozzila/plugins
ln -s /opt/java/jdk1.7.0_25/jre/lib/amd64/libnpjp2.so ~/.mozzila/plugins/

I followed the Tutorial that describes how to install using the ppa created by webupd8.org. (Search for the that article.)

There are simpler ways to get Java onto the machine than this convoluted article shows.

The instructions are a bit terse, there is plenty of room for stuff to go wrong,
for instance:
I have a non standard location for my downloads even though I fixed it so that it still looks like it is under my home directory so when i did your step 5 I got a mass of errors that quickly zipped off the screen and if I hadnt noticed them would have left my Java folder short of a couple of hundred of the most important files, I looked in the folder and it had lots of stuff there so thought maybe they had been warnings went and had a look it was a permission thing I went back to step 5 and added sudo to the beginning of your first line and it went thru.

Also in your final Optinal(sic) step you have mispelled mozilla - not sure if thats an issue actually but makes me a bit suspicious that you didnt actually run those commands - just typed them here. And there is simply not enough information there to know how the .mozilla/plugins folder will be used and by who, I had a look around and firefox has a couple of plugins directories but not there, and will this work for multiple users or just me?

This is all intended as constructive criticism, I appreciate the effort you put into it, I just dont want anyone to come to grief because of it.

Second the comment from sbrbot.
This guide works good but the other is easier to maintain.

Here is another (I must say better) article about how to install Oracle JDK because it suggest creating "current-java" folder which allows easier upgrade of JDK version.

Fantastic, thanks. I also re-used your step 8 to set javac, the java compiler, for use in IDEs when programming in Java (IntelliJ and JBoss). Cheers.

Here is a more complete version:
http://community.linuxmint.com/tutorial/view/1839

This version:
* Allows for easy updating
* Updates more of the various jdk executables (ie: jar, keytool, servertool, etc)
* Has a fancy helper tool to help with the 'update-alternatives' commands!
* Does not allow for multi-versioning by default but you can modify the guide to make it so

Great! Concise and to the point. Thank you!

Note that I think you need a 2nd sudo in the JDK removal command set.

Big help for a noob like me! Thanks again!
