Full Discussion: java errors when calling from cron
Top Forums Shell Programming and Scripting java errors when calling from cron Post 31996 by Vishnu on Saturday 16th of November 2002 06:00:00 AM

May be as simple as not using absolute paths or not exporting env. variables
most differences in behavior we see between cron running a job and manual runs is because of differences in path setting...

it is always imperative to use absolute paths (starting from /) in all the directory paths in your script...

similarly I hope that you export all the relevant environment variables (like PATH etc) in the very beginning of your shell script... if you run a script manually it will inherit all the env. variables of your logon shell (some of them may be set in your .profile).. if you run a script using cron it will inherit all the cron user's env. variables... you need to ensure within the script that all required env. variables are explicitly set and exported, so that these hold the same values for the subsequent commands using them - both in cron and manual modes...

the java exception you show indicates that a java class was not found in the class path...

Hope this helps...

Cheers!
Vishnu.

uudemon.cleanu

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
