I am running a web-application (MyCronTest) on a Glassfish-Server in a Jelastic-Environment. This web-application contains the servlet (/test), that I would like to call regularly with a cron-job.
So I followed this tutorial from the Jelastic docs, but they use Tomcat instead of Glassfish and I am not so sure about the paths and where to put which file...and now I am lost ;)
the servlet
When calling the servlet directly in my browser it prints out the following line to System.out:
test executed at 05/03/2014 15:00
the bash file to execute
I created a bash script called myCronJob.sh and put it in the directory glassfish3/temp:
#!/bin/bash
curl http://myGlassfish.jelastic.dogado.eu/MyCronTest/test;
I tested it of course, it is executable and it works (at least when I execute it on my computer).
the cron event scheduler
according to the tutorial there is a file /cron/tomcat I need to edit. Well, I found a /cron/glassfish which (I am guessing) should do the same.
# IMPORTANT NOTE!
# Please make sure there is a blank line after the last cronjob entry.
*/1 * * * * /opt/glassfish3/temp/myCronJob.sh
I added an empty line at the end, as they told me to. I even tried it with
*/1 * * * * /bin/bash /opt/glassfish3/temp/myCronJob.sh
as they suggested in the tutorial. But still no output. No error.. just empty log files.
Does anyone have an idea what I am missing here? Am I doing something wrong?
Solution / Edit
Thanks to Damien's Answer I was finally able to narrow down my problem. It was actually the line in my bash-script that caused the problem:
curl http://myGlassfish.jelastic.dogado.eu/MyCronTest/test;
should have been
curl http://localhost/MyCronTest/test;
since I was blocked by a firewall. Lucky for me, my Glassfish is running on the same machine / environment, so localhost works.
Everything else is correct.
