How to set JAVA_HOME environment variable in 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

 

When you reboot, try running the following:

 

    $ echo $JAVA_HOME
/usr/lib/jvm/java
 echo $PATH
[probably lots of paths]:/usr/lib/jvm/java/bin
