Tomcat 4.1 and Apache 2 on Ubuntu Linux

Short Version.

• Install java (JDK not JRE). (Download binary from java.sun.com, add executable permission, run, move resulting directory to /usr/local or similar.)
• Install apache2.
• Get Tomcat binary from tomcat.apache.org and extract to /usr/local/
• Set an environment variable CATALINA_HOME to the path of the directory into which you have installed Tomcat 4.0. And another JAVA_HOME to the path of the directory into which you have installed Java.
• Execute the shell command: $CATALINA_HOME/bin/startup.sh
• Check Tomcat works on port 8080
• Install jk2 connector (sudo apt-get libapache2-mod-jk2)
• Copy /usr/share/doc/libapache2-mod-jk2/examples/workers2.properties.minimal to /etc/apache2/workers2.properties adding in your own config
• Uncomment line in /etc/apache2/mods-available/jk2.conf
• Place your Tomcat-related code in CATALINA_HOME/webapps/ROOT or other appropriate directory. Restart everything.
