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.

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME
tcp-env - set up TCP-related environment variables SYNOPSIS
tcp-env [ -rR ] [ -ttimeout ] program [ arg ... ] DESCRIPTION
The input for tcp-env must be a TCP connection. tcp-env finds out information about that connection, puts the information into several environment variables as described in tcp-environ(5), and runs program with the given arguments. Usually tcp-env is run from inetd. It might instead be run from another server that already sets up the right environment variables; if PROTO is set to TCP when tcp-env is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check whether the input is a TCP connection. OPTIONS
-r (Default.) Attempt to obtain TCPREMOTEINFO from the remote host. -R Do not attempt to obtain TCPREMOTEINFO from the remote host. -ttimeout Give up on the TCPREMOTEINFO connection attempt after timeout seconds. Default: 30. SEE ALSO
tcp-environ(5), inetd(8) tcp-env(1)
