JAVA_HOME on Linux Bash



How to Set JAVA_HOME / PATH variables Under Linux Bash Profile


If the command echo $JAVA_HOME returns no result , 
it means that JAVA has no HOME and could not work properly
in Palo OLAP Server with embedded Tomcat .

The following command shows the path to java executable on Linux : 
# which java
WHICH command result on Ubuntu , Mint :
/usr/bin/java

after EXPORT command : 
export JAVA_HOME=/usr/bin/java
if we check again , JAVA has a HOME
# echo $JAVA_HOME
 /usr/bin/java

if I'm running again the script setclasspath.sh from 
/opt/jedox/ps/tomcat/bin
the result is :
The BASEDIR environment variable is not defined

This environment variable is needed to run this program

Tomcat & catalina issues

The error message says you have to set the environment variable BASEDIR.
Set it to the Tomcat installation directory, for example:


export BASEDIR=/usr/local/tomcat



echo $BASEDIR
/usr/local/tomcat
