Jre 1.3.1_01 Self extracting for Solaris.

Question

Im in the middle of making an app for college (Part of my final year project)
Basically I want to install the JRE 1.3.1_01 onto the PC for the app, but I need this process to be transparent to the user installing it.
I have opened the
JRE 1.3.1_01.sn
in the script we get the followign
#!/bin/sh
PATH=/usr/bin:/bin
libthread_path=
more <<"EOF"
**agreement text**
EOF
agreed=
while [ x$agreed = x ]; do
echo
echo "Do you agree to the above license terms? [yes or no] "
read reply leftover
case $reply in
     y* | Y*)
     agreed=1;;
     n* | n*)
echo "If you don't agree to the license you can't install this sofware";
exit 1;;
esac
done
outname=install.sfx.$$
trap 'rm -f $outname; exit 1' HUP INT QUIT TERM
echo "Unpacking..."
tail +276 $0 > $outname
if [ -x /usr/bin/sum ] ; then
echo "Checksumming..."
sum=`/usr/bin/sum $outname`
index=1
for s in $sum
do
     case $index in
     1) sum1=$s;
     index=2;
     2) sum2=$s;
     index=3;
     esac
done
if expr $sum1 != 32212 || expr $sum2 != 30194 ; then
     echo "The download file appears to be corrupted. Please refer"
     echo "to the Troubleshooting section of the Installation"
     echo "Instructions on the download page for more information."
     echo "Please do not attempt to install this archive file."
     exit 1
fi
else
echo "Can't find /usr/bin/sum to do checksum. Continuing anyway."
fi
chmod +x $outname
echo "Extracting..."
./$outname
if [ -n "$libthread_path" ] && [ -f "$libthread_path/`uname -r`/libthread.so.1" ]; then
echo "Making libthread links"
ln -s `uname -r`/libthread.so.1 $libthread_path/libthread.so.1
ln -s libthread.so.1 $libthread_path/libthread.so
fi
echo "Done."
rm -f $outname
exit 0
Basically I have changed more at the very top, to cat, which displays the entire agreement, and I made the agreed variable equal 1, so the installer always agrees to the licence text.
The problem is with the checksum I keep getting errors, mainly about the file being corrupt and it not liking that.
By removing
if expr $sum1 != 32212 || expr $sum2 != 30194 ; then
     echo "The download file appears to be corrupted. Please refer"
     echo "to the Troubleshooting section of the Installation"
     echo "Instructions on the download page for more information."
     echo "Please do not attempt to install this archive file."
     exit 1
fi
else
It skips and goes straight to the install but installs garbage . Any suggestions on making it work. I plan to package up the changed Script and put my own checksum onto it, and incorporate it into my overall project.

Problem is simple, your failing MD5 check for file.
Since this is not legal what you doing, so I will not tell you work around
