Oracle JDK is no longer included by default in Ubuntu’s repositories due to licensing. OpenJDK is default now but many apps still don’t play nice with it. This is why I installed Oracle JDK.

I’ll walk you through the process of installing Oracle JDK 7 on Ubuntu 12.04 LTS Precise Pangolin, the easy way. For this we will use the “install oracle-java7-installer” package from “WEBUPD8”.

The “install oracle-java7-installer” package from “WEBUPD8” will download the official binaries from Oracle and install the JAVA 7 JDK, JRE and browser plugins on your machine.

  1. Add the “WEBUPD8” PPA.

    [email protected]:~$sudo add-apt-repository ppa:webupd8team/java 

  2. Update your repositories.

    [email protected]:~$sudo apt-get update 

  3. Install JAVA 7 JDK.

    [email protected]:~$sudo apt-get install oracle-java7-installer

To uninstall,

sudo apt-get remove oracle-java7-installer

Did it work for you? [Test here][2]
