## 1. Installing Pre-requisites

Before building and running the GreenPages sample, it is essential to install a JDK, Virgo Tomcat Server and Apache Maven.

## 1.1 Installing a JDK

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.)
