Oracle JDK : how to create deb

http://www.santasoft.it/en/blog/20120910_flash-install-oracle-java-7-jdk-debian-way :

sudo apt-get install java-package

Download JDK tar.gz from Oracle's website:
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

fakeroot make-jpkg jdk-7u60-linux-x64.tar.gz

A deb file is created in the same directory. Install the created deb file using
sudo dpkg -i oracle-j2sdk1.7_1.7.0+update60_amd64.deb

 sudo update-alternatives --config java

oracle-jdk-7 403 forbidden or The request or reply is too large

While trying to install cloudera manager I keep getting 403 Forbidden when it tries to install oracle-jdk -7.
When  I tried downloading the file manually I kept getting "The request or reply is too large."

1. One potential solution:
http://askubuntu.com/questions/453367/download-failed-oracle-jdk-7-is-not-installed

after getting error 403, use ls:

ls /var/cache/oracle-jdk7-installer/

download the JDK tar.gz from someplace else on web (google archive filename) and compare its md5 checksum against the one given on oracle's website.

sudo cp ~/Downloads/jdk-7u55-linux-x64.tar.gz /var/cache/oracle-jdk7-installer/

sudo apt-get install oracle-java7-installer

2. Found out why it was happening:
The local network went through squid proxy that had a 100MB limit. The JDK archive is 130+ MB
Moved to another network and it started installing :P
