JDK

Tue Jun 25 04:54:16 UTC 2013

Ubuntu is based on Debian, you cannot install RPM packages the same way 
you do on a Red Hat or CentOS machine.  Debian/Ubuntu 'packages' are 
usually in a .deb file.

For Oracle JDK however, there is no .deb file.  Webupd8 has very well 
maintained PPA to easily get Oracle Java installed and running with just 
a few commands.

Here are the 3 commands you need to run assuming you haven't screwed up 
your system too badly trying to install an RPM on a Debian/Ubuntu 
system, ;).

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

First command adds the PPA, which can be thought of as a repository.  
Second command, updates your available packages taking this new PPA into 
account.  Third, downloads and runs the Java JDK/runtime installer from 
that webupd8 PPA.

That installer is by far the easiest way to get Java going.  It uses the 
actual Java download directly from Oracle, but handles the messy install 
since there is no official .deb.

More details on the Webup8 PPA for Java can be found on there site, 
http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html.
