java environment + cron issue

[John Sidney-Woollett <jo...@wardbrook.com>]

On a unix RH8 box starting and stopping TC 5.0.18 under the root account
using the following script:

#!/bin/sh
# This script stops tomcat for (about) 1 minute, and then restarts it
# it is run at the same time as the script to backup the
# database (which is shutdown, and a file level copy made)
echo "Stopping Tomcat at `date`"
/usr/local/jakarta-tomcat-5.0.18/bin/shutdown.sh
echo "Tomcat shutdown at `date`"
sleep 15
echo "Starting Tomcat at `date`"
/usr/local/jakarta-tomcat-5.0.18/bin/startup.sh

stops and starts TC as expected, and after TC is restarted all my JSP's
correctly render UTF-8 strings.

However if the script is invoked from cron, the JSPs render all
non-standard ASCII characters (like accented ones) as a ? (question
mark), until TC is restarted again by executing the above script under
the root account.

Does anyone know what the cause of the problem is, and how to fix it?

(We will be upgrading to TC 5.0.28 shortly, but I don't think the TC
version is the issue). There must be some kind of enviroment issue going
on that I don't understand.

Thanks

John Sidney-Woollett

ps here is the cron entry (created using crontab -e from the root account).

You might try compare results of /usr/bin/env executed from cron
and command-line.
You may need to set some environment variables, LANG for example,
to make JVM works as you expected.

Hope this helps.

I don't know the cause of your problem, but personaly I use nohup to 
start commands from cron :
nohup /usr/local/jakarta-tomcat-5.0.18/bin/shutdown.sh

nohup manage in good way standard input and output (you can pass 
options) and keep your task running after father task die.

Hope it help.
