Re: Error crawl in cygwin cron.

[Siddhartha Reddy <si...@grok.in>]

The environment in which cronjobs run is not the same as the environment in
which applications that are started from the console run. The cronjob
environment usually has fewer environment variables set (those environment
variables set in /etc/profile or any of the bash rc scripts do not get
exported to the cronjob environment); in this case, the JAVA_HOME
environment is not set for the cronjob.

Assuming you are in Linux (this does not work for FreeBSD, I reckon), you
can set the JAVA_HOME environment variable for your cronjobs by adding the
following line at the beginning of the crontab:

JAVA_HOME=/path/to/java_home

Cron will automatically export the above environment variable before running
your script.
