Java Home

If you are getting java_home is not defined correctly in Ubuntu, then you are at right place.

I was getting this error as I was trying to update the Java home in ~\.bashrc and ~\.bash_profile. Follow these steps to solve this issue.

1. Open the /etc/environment file as

   vim /etc/environment
   

2. Then set java_home using

   JAVA_HOME="/usr/lib/jvm/java-8-oracle"
   export JAVA_HOME
   

3. Open bash profile as

   vim ~\.bash_profile
   

4. Then add the following,

   .  /etc/environment
   

   It will load the /etc/environment every time terminal is started

5. Then confirm the path using

   echo $JAVA_HOME
