Install Oracle Java JDK on Amazon Linux AMI

The version of Java on Amazon AWS Linux AMI is not the version of Oracle's JDK.

If you want to use the Oracle / Sun version and upgrade Java version:

wget --no-cookies --header "Cookie: gpw_e24=xxx;" http://download.oracle.com/otn-pub/java/jdk/7u25-b15/jdk-7u25-linux-x64.rpm

install...

sudo rpm -i jdk-7u1-linux-i586.rpm 

Check Java home and will probably be: /usr/lib/jvm/jre

echo $JAVA_HOME

change to path to JDK you installed:

export JAVA_HOME=/usr/java/jdk1.7.0_25

export PATH=$PATH:/usr/java/jdk1.7.0_25/bin
