Issue
I tried to shutdown tomcat as shown below, but tomcat still seems to be running (http://localhost:8080/)
vandegraff@vandegraff-laptop:~$ /usr/share/tomcat6/bin/shutdown.sh Using CATALINA_BASE: /usr/share/tomcat6 Using CATALINA_HOME: /usr/share/tomcat6 Using CATALINA_TMPDIR: /usr/share/tomcat6/temp Using JRE_HOME: /usr 1 Nov, 2010 11:41:40 PM org.apache.catalina.startup.Catalina stopServer SEVERE: Catalina.stop: java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at java.net.Socket.connect(Socket.java:478) at java.net.Socket.<init>(Socket.java:375) at java.net.Socket.<init>(Socket.java:189) at org.apache.catalina.startup.Catalina.stopServer(Catalina.java:422) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.catalina.startup.Bootstrap.stopServer(Bootstrap.java:337) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:415)
Why is that?
Update1 for @hvgotcodes:

Should all these 3 processes - 1597, 1598, 1599 - be killed?
Solution
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.
