Installing Sun Java SE 6, Apache Maven 2 and Tomcat 5.5 on Ubuntu GNU/Linux
Installing Sun Java SE 6, Apache Maven 2 and Tomcat 5 on Ubuntu GNU/Linux

Installing Java SE 6, Apache Maven 2 and Apache Tomcat 5.5 software is just one simple command on Ubuntu family of GNU/Linux operating systems:
I recommend setting JAVA_HOME environment variable to point to the JDK installation directory in your profile file(e.g. .bash_profile or /etc/profile):
export JAVA_HOME /usr/lib/jvm/java-6-sun
The above command also installs the jetty web server which is especially good for development purposes.
