Before building and running the GreenPages sample, it is essential to install a <span class="emphasis"><em>JDK</em></span>,
<span class="emphasis"><em>Virgo Tomcat Server</em></span> and <span class="emphasis"><em>Apache Maven</em></span>.
</p><div class="section" title="Installing a JDK"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="installation.prereqs"></a>Installing a JDK</h2></div></div></div><p>
Before proceeding, ensure that a Java<span class="trademark"></span>&trade; Standard Edition Development Kit (JDK)
for Java 6 or later is installed and that the <code class="literal">JAVA_HOME</code> environment variable 
is set to the root directory of the JDK.
(<span class="emphasis"><em>A Java Runtime Environment (JRE) alone is not sufficient for building the sample.</em></span>)
