How to SHUTDOWN Tomcat in Ubuntu?

Try using this command : (this will stop tomcat servlet this really helps)

sudo service tomcat7 stop

or

sudo tomcat7 restart (if you need a restart)

Try

/etc/init.d/tomcat stop

(maybe you have to write something after tomcat, just press tab one time)

Edit: And you also need to do it as root.

To stop apache process try this command

ps aux | grep tomcat | awk '{print $2}' | xargs kill -9

Van, in your case where tomcat won't shutdown normally, i would use

ps ax | grep java

to find the java process number. If that command returns something, then run

sudo kill -9 pid

where pid is the process number. The -9 option means 'just kill it', and normally you don't need this sort of thing, but since in your situation the process won't stop normally, you need it.

The output of the first command should look like

38678 s002  U      0:02.62 /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home/bin/java -Djava.util.logging.config.file=/usr/share/apache-tomcat-6.0.26/conf/logging.properties -Xms2048m -Xmx2048m -XX:PermSize=256m -XX:MaxPermSize=512m -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8086 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=xxxx -Djava.endorsed.dirs=/usr/share/apache-tomcat-6.0.26/endorsed -classpath /usr/share/apache-tomcat-6.0.26/bin/bootstrap.jar -Dcatalina.base=/usr/share/apache-tomcat-6.0.26 -Dcatalina.home=/usr/share/apache-tomcat-6.0.26 -Djava.io.tmpdir=/usr/share/apache-tomcat-6.0.26/temp org.apache.catalina.startup.Bootstrap start

38678 is the process number. Be aware that there might be other java processes running that you might not want to kill. Also, this output is from a mac, so on ubuntu will look slightly different.
