Crontab java.lang.ClassNotFoundException with a jar file

Question

 #!/bin/bash 
 JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk
 CLASSPATH=/Users/sunny/CronTest/out/production/CronTest 
 $JAVA_HOME/Contents/Home/bin/java -cp $CLASSPATH ".:/Users/sunny/Downloads/sqlite-jdbc-3.8.11.2.jar" sample.Main 
 exit 0

Sqlite jar file is in /Users/sunny/Downloads/sqlite-jdbc-3.8.11.2.jar

Compiled java class file is in /Users/sunny/CronTest/out/production/CronTest/sample/Main.class

And I've set the cron job to be schedule at every 1 minute. Java class is getting exucuted but I am getting java.lang.ClassNotFoundException: org.sqlite.JDBC
Same command which is in script is working in terminal.

My question is how can I add jar file properly to be executed from shell script.

Answer 1

Seems there is a space in between your $CLASS PATH and ".:/Users/sunny/Downloads/sqlite-jdbc-3.8.11.2.jar" and missing a colon(:).

Please try with following with export :

export CLASSPATH=.:/Users/sunny/CronTest/out/production/CronTest:/Users/sunny/Downloads/sqlite-jdbc-3.8.11.2.jar

and call java command with -cp $CLASSPATH .

If it still not work, please try with -cp directly:

$JAVA_HOME/Contents/Home/bin/java -cp ".:/Users/sunny/CronTest/out/production/CronTest:/Users/sunny/Downloads/sqlite-jdbc-3.8.11.2.jar" sample.Main
