Not able to set JAVA_HOME variable in ubuntu 14.04 on manual installation

I've downloaded java jdk1.8.0.7.tar.gz file from the official website and unzipped it into my home directory. Now to set the $JAVA_HOME variable I used the follwing commands command nano .bashrc and then appending export $JAVA_HOME=/home/shivam/Java/jdk1.8.0.7 at the end of the file .

But whenever I run the command sudo $CATALINA_HOME/bin/startup.sh I get an error message saying 

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program


I don't understand why it is unable to find the java path though I've installed tomcat and set its home variable the this way, which worked.
I wan't to install Java manually without using apt-get.
Kindly guide .

Try add the following 2 lines in your .bashrc file:

JAVA_HOME=/home/shivam/Java/jdk1.8.0.7/
export JAVA_HOME

You want to append the following to .bashrc:

JAVA_HOME=/home/shivam/Java/jdk1.8.0.7

Note the missing $ at the start.

Also remember that the file won't effect your current shell without sourceing it first.

Also, when running a command with sudo, you are running it as the root user, not as yourself. So the environment variable needs to be set for the root user, not yourself.

You can run sudo env | grep JAVA_HOME to see whether it is set for root.
