This describes the installation and configuration for a Tomcat server running on a Linux environment platform and how to download install/update the Java version. Windows installations can apply these configurations in a similar manner. If you are unable to complete any of these steps because the command does not exist (e.g. service tomcat7 start, openssl dgst -md5 tomcat.tar.zip) then please contact SysAdmin for assistance.

FINAL STEPS - REALLY IMPORTANT
Finally cd to $CATALINA_HOME and execute the following command - sudo chown -R tomcat:nobody ./
This will make the tomcat user owner for all files allowing for read/write access - otherwise the server will not start because it cannot log or read certain files.
Remember - have fun!
