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

CRON(8) System Manager's Manual CRON(8) NAME
cron - clock daemon SYNOPSIS
/usr/sbin/cron DESCRIPTION
Cron executes commands at specified dates and times according to the instructions in the files /etc/crontab and /etc/crontab.local. None, either one, or both of these files may be present. Since cron never exits, it should only be executed once. This is best done by running cron from the initialization process through the file /etc/rc; see init(8). The crontab files consist of lines of seven fields each. The fields are separated by spaces or tabs. The first five are integer patterns to specify: o minute (0-59) o hour (0-23) o day of the month (1-31) o month of the year (1-12) o day of the week (1-7 with 1 = Monday) Each of these patterns may contain: o a number in the range above o two numbers separated by a minus meaning a range inclusive o a list of numbers separated by commas meaning any of the numbers o an asterisk meaning all legal values The sixth field is a user name: the command will be run with that user's uid and permissions. The seventh field consists of all the text on a line following the sixth field, including spaces and tabs; this text is treated as a command which is executed by the Shell at the specified times. A percent character (``%'') in this field is translated to a new-line character. Both crontab files are checked by cron every minute, on the minute. FILES
