Question Crontab not recognizing the jar files

Hi All,
I am using crontab which execute a shell script.
In the shell script, I am executing a java program. This Java program requires the jar files.
The cron job file ' cronfile.txt ' contents:

MAILTO="raju_utla@dcis.uohyd.ernet.in"
0-59 * * * * ./cronfile.sh >> /home/rajuutla/FilesForCronJob/logFileForCron.log

The shell script( cronfile.sh ) contents :
#!/bin/bash
#check weather server prog is running or not
test=`ps aux | grep -c java\ PostgresServer`
JAVA_HOME=/opt/SDK/jdk
CLASSPATH=/home/rajuutla/pg74.jdbc3.jar:.
if [ $test -eq 1 ]
then
echo `date`
$JAVA_HOME/bin/java -classpath $CLASSPATH PostgresServer

fi

The java program 'PostgresServer' which i am executing requires the jar file
'pg74.jdbc3.jar' mentioned above.

The problem is, directly running the above shell script with out cron, I am able to get the results. But when I use the crontab to run the java program I am not able to get the results.

What may be the problem? How to resolve this problem? I am unable to find it out.
Please help me.
Thanks to All.
Raju

Not entirely sure if it will help, but have you tried to export CLASSPATH ...

ie: export CLASSPATH=/home/rajuutla/pg74.jdbc3.jar:.

is that a real mail id ? if so, please remove that or provide a fake one

problem with the question - able to run in shell but not in cron is attributed greatly to the environment variables that are needed to run a process which are available via shell automatically or set as a one time configuration. But that might not be the case when run via cron, explicitly provide all the needed environment variables needed to run the process

Raju,

Please do yourself a favour and read the posts attached to the link I provided.
Whilst the export solution I initially posted has resolved your problem, the kink provided will help you perhaps better identify what you could/should be doing to better avoid the same issue. (IMHO).

Anyways - good to hear you're back on track again.

Cheers,
Cameron
