Set JAVA_HOME Under ubuntu

One way that you can set your JAVA_HOME variable and add to your PATH, is be doing the folowing.  As 'sudo' open up /etc/bash.bashrc and add the following to the end of the file.  NOTE: Set the java path to whatever the actual path is on your environment if it does not match /usr/lib/jvm/java

JAVA_HOME=/usr/lib/jvm/java

export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH
