====== Install java 7 on linux by hand ======

**Upgrading the alternatives system for a just downloaded Java**

The best and more complete instructions I have found are these: http://askubuntu.com/questions/55848/how-do-i-install-oracle-java-jdk-7

I reproduce them for just in case the other site dissapears the entry.

[[InstallJdk8AlternativesUbuntu|The same for Java 8]]

===== Download and uncompress java =====

Download the java binaries and uncompress them. Let's say you have downloaded into /usr/java. 

Oracle guys usually install it on /usr/java, creating two links: default and latest, who points to the just installed java version. 

So, the current java version will be in /usr/java/default

===== Create an alteratives system for the new java =====

Create a file /usr/java/current/.java-1.7.0-oracle.jinfo with the following content: 

<code shell>
