I have an executable jar and I have written a shell script to execute it. When I run the shell script manually, it runs fine but when schedule to run it weekly using crontab, it gives the following error -
log_process.sh: line 16: java: command not found
Line 16 in my shell script is -
java -jar $jar_path $logDirectory $logNamePattern $processedLogDirectory $oldResultsDirectory 2>>$log_file 1>&2
Any idea why is it happening that it runs fine when I run it manually but not when it gets run by vrontab job?
Your cron job doesn't have access to the same $PATH variable that you as a user have.
The easiest way to fix this is to open up a terminal, and run this command:
That's going to give you the absolute path of your java executable. For example:
Replace your 'java' command with the whole path.
You might also want to specify the JAVA_HOME variable in your shell script. From your terminal run:
That'll give you another path, like '/opt/Oracle/Java'. In your script (assuming you are using bash), before you run the java command, put:
Replacing '/opt/Oracle/Java' with the output that the previous echo gave you.
