Crontab to run a java shell script on linux

Question

Am writing a simple java script to send email it works perfectly however it does work in the crontab. the command sh sendmail.sh works

Here is my crontab command from crontab -e

*/5 * * * * sh  user /home/user/classes/sendmail.sh

I expect this to work and send mail every 5 minutes but it doesn't work

However the command sh sendmail.sh works

I need help on the crontab

Your cron expression is correct, can you give us additional details? — vmr

java -classpath .:mail.jar:imap.jar:dsn.jar:smtp.jar:gimap.jar:mailapi.jar:pop3.jar email.Email nothing happens from the crontab job and no email is sent — lawal yemi

Note- By default crontab sends a mail to user account executing the cronjob, why dont you make use of it? — vmr

Your correct lines is the following

*/5 * * * * user /home/user/classes/sendmail.sh (without "sh" word)

You have to be aware that user "user" has permission to execute the script "sendmail.sh"

You can see that executing ls -la sendmail.sh and reading who is the owner and the permissions.
