      The additional components are built using the <code>extras</code> target
      of the standard Tomcat Ant script which is present in the source bundle of
      Tomcat.

    <p>The build process is the following:</p>

    <ul>
    <li>Follow the <a href="building.html">build instructions</a> to build a
        Tomcat binary from the source bundle (note: it will be used by the build
        process of the additional components, but does not need to be actually
        used later on)</li>
    <li>Execute the command <code>ant extras</code> to run the build
        script</li>
    <li>The additional components JARs will be placed in the
        <code>output/extras</code> folder</li>
    <li>Refer to the documentation below about the usage of these JARs</li>

  <p>
    Tomcat uses a package renamed commons-logging API implementation which is
    hardcoded to use the java.util.logging API. The commons-logging additional
    component builds a full fledged package renamed commons-logging
    implementation which can be used to replace the implementation provided with
    Tomcat. See the <a href="logging.html">logging</a> page for usage
    instructions.

  <p>
    The JMX protocol requires the JMX server (Tomcat in this instance) to listen
    on two network ports. One of these ports can be fixed via configuration but
    the second is selected randomly. This makes it difficult to use JMX through
    a firewall. The JMX Remote Lifecycle Listener allows both ports to be fixed,
    simplifying the process of connecting to JMX through a firewall. See the <a href="config/listeners.html">listeners</a> page for usage instructions.
