Java 7 installation

OS: Debian Wheezy

Installation instruction is on https://wiki.debian.org/JavaPackage which requires debian package building utilities.

Java 7 JDK file is jdk-7u45-linux-x64.tar.gz

Creating debian Java package
$ make-jpkg jdk-7u2-linux-x64.tar.gz

It showed bunch of warning messages during the package build but would generate a package file like this oracle-j2sdk1.7_1.7.0+update45_amd64.deb.
Package installation is followed by

$ sudo dpkg -i oracle-j2sdk1.7_1.7.0+update45_amd64.deb

java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

Java plugin installation for Google Chrome (Version 30.0.1599.114)

The instruction I followed is here.

Make /opt/google/chrome/plugins directory if it doesn’t exist. Then create a symbolic link for the Java plugin file at /usr/lib/jvm/j2sdk1.7-oracle/jre/lib/amd64/

mkdir /opt/google/chrome/plugins
cd /opt/google/chrome/plugins
$ sudo ln -s /usr/lib/jvm/j2sdk1.7-oracle/jre/lib/amd64/libnpjp2.so

In Chrome typing “chrome://plugins/” in the address or search bar will show the Java plugin among other plugins.
