Before building and running the GreenPages sample, it is essential to install a JDK, Virgo Tomcat Server and Apache Maven.
Before proceeding, ensure that a Java™ Standard Edition Development Kit (JDK)
for Java 6 or later is installed and that the
JAVA_HOME environment variable
is set to the root directory of the JDK.
(A Java Runtime Environment (JRE) alone is not sufficient for building the sample.)
