Tomcat6 on Ubuntu

Need help from Tomcat and Ubuntu user group..

I have the following script to start / stop / restart my tomcat server on ubuntu OS. Start is working fine but when i try to stop i am getting syntax syntax error below..

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0

case $1 in
start)
sh /usr/local/tomcat/bin/startup.sh
;;
stop)
sh /usr/local/tomcat/bin/shutdown.sh
;;
restart)
sh /usr/local/tomcat/bin/shutdown.sh
sh /usr/local/tomcat/bin/startup.sh
;;
esac
exit 0

Here is the error..
Using CATALINA_BASE: /usr/local/tomcat

Best I can figure out is that maybe your shutdown.sh script has been damaged.

Try this shutdown command instead and see what happens:

sh /usr/local/tomcat/bin/catalina.sh stop
