If  you are getting the  above error while stopping  or starting Tomcat  service from shell as ./shutdown.sh  or ./startup.sh then it  means that the

JAVA_HOME

variable is either not defined or incorrectly defined.
You can fixed this by running the below commands from Shell as root user :

root@server[#] which java

you will get the below output :
/usr/local/jdk/bin/java

then run this command

root@server[#] export JAVA_HOME=/usr/local/jdk

after that try running the command

root@server[#] cd /usr/local/jakarta/tomcat/bin
root@server[#] ./shutdown.sh or ./startup.sh

you will get the output for ./shutdown.sh
