title: JRE/java command not found
body: <p>I'm trying to install JRE on Ubuntu 13.10. I followed this <a href="http://ubuntuhandbook.org/index.php/2013/07/install-oracle-java-6-7-8-on-ubuntu-13-10/" rel="nofollow">guide</a>. When I run "java -version" it says "command not found"... </p>
  
  <p>This is the result of "sudo find / -name java"</p>
