It is grounded in Java’s Reflection API. Classes in the <code class="literal">java.lang.reflect</code> represent Java methods and classes, such that you can instantiate objects and invoke their methods based on their names and argument types.
Behind the scenes, Jetty’s XML config parser translates the XML elements and attributes into Reflection calls.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="using-jettyxml"></a>Using jetty.xml</h3></div></div></div><p>To use <code class="literal">jetty.xml</code>, specify it as a configuration file when running Jetty.</p><pre xmlns:jfetch="java:org.eclipse.jetty.xslt.tools.JavaSourceFetchExtension" xmlns:fetch="java:org.eclipse.jetty.xslt.tools.SourceFetchExtension" xmlns:d="http://docbook.org/ns/docbook" xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0" xmlns:xslthl="http://xslthl.sf.net" xmlns:gcse="http://www.google.com" xmlns:date="http://exslt.org/dates-and-times"><code> java -jar start.jar etc/jetty.xml</code></pre><div class="blockquote"><blockquote class="blockquote"><div xmlns:jfetch="java:org.eclipse.jetty.xslt.tools.JavaSourceFetchExtension" xmlns:fetch="java:org.eclipse.jetty.xslt.tools.SourceFetchExtension" xmlns:d="http://docbook.org/ns/docbook" xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0" xmlns:xslthl="http://xslthl.sf.net" xmlns:gcse="http://www.google.com" xmlns:date="http://exslt.org/dates-and-times" class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title"><i class="fa fa-asterisk" aria-hidden="true"></i> Note</h3><p>If you start Jetty without specifying a configuration file, Jetty automatically locates and uses the default installation <code class="literal">jetty.xml</code> file.

The ID of the server in the <code class="literal"><Configure></code> tag specifies the instance you want to configure.
Each server ID in a configuration file creates a new server instance within the same JVM.
If you use the same ID across multiple configuration files, those configurations are all applied to the same server.</p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="setting-parameters-in-configuration-files"></a>Setting Parameters in Configuration Files</h3></div></div></div><p>You can set parameters in configuration files either with system properties (using <code class="literal"><SystemProperty></code>) or properties files (using <code class="literal"><Property></code>) passed via the command line.
