We need to set JAVA_HOME a lot of times in linux. Here is the procedure for setting JAVA_HOME in linux (i tested this only on Ubuntu, but i think, it should work in all linux distributions).

To Set JAVA_HOME:

Step 1: Open Terminal

Step2: as sudo, open /etc/bash.bashrc file (sudo gives administrative privilege to user in Ubuntu, for other linux distributions type su then hit enter, it will ask for root password, enter the password and then open /etc/bash.bashrc file)

Step3: add following lines at the end of the file:

view source print ?

 
JAVA_HOME=/usr/lib/jvm/java 
 
export JAVA_HOME 
 
PATH=$PATH:$JAVA_HOME/bin 
 
export PATH

Step4: Reboot the computer.

For checking, if JAVA_HOME is set or not, in terminal type:

echo $JAVA_HOME and hit enter, if you get: /usr/lib/jvm/java or /usr/lib/jvm/java* (java* means something after java) then you have set JAVA_HOME correctly and if you get nothing (blank line) or something else, then there is some problem with JAVA_HOME environment setting.
