| The simplest way to do this is to create multiple <code class="literal">Server</code> instances. |
| However, if contexts need to share resources (eg data sources, authentication), or if the mapping of ports to web applications is not cleanly divided, then the named connector mechanism can be used.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="creating-server-instances"></a>Creating Multiple Server Instances</h3></div></div></div><p>Creating multiple server instances is a straight forward process that includes embedding Jetty code by creating multiples instances of the Server class and configuring them as needed. |
| This is also easy to achieve if you are configuring Jetty servers via XML. |
| The <code class="literal">id</code> field in the Configure element of <code class="literal">jetty.xml</code> files is used to identify the instance that the configuration applies to, so to run two instances of the Server, you can copy the <code class="literal">jetty.xml</code>, jetty-http.xml and other jetty configuration files used and change the "Server" id to a new name. |
| This can be done in the same style and layout as the existing <code class="literal">jetty.xml</code> files or the multiple XML files may be combined to a single file.</p><p>When creating new configurations for alternative server:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">Change all <code class="literal">id="Server"</code> to the new server name:</li></ul></div><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><Configure id="OtherServer" class="org.eclipse.jetty.server.Server"></code></pre><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">For all connectors for the new server change the <code class="literal">refid</code> in the server argument:</li></ul></div><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><Arg name="server"><Ref refid="OtherServer" /></Arg></code></pre><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem">Make sure that any references to properties like <code class="literal">jetty.http.port</code> are either renamed or replaced with absolute values.</li><li class="listitem">Make sure that any deployers <code class="literal">AppProviders</code> refer to a different "webapps" directory so that a different set of applications are deployed.</li></ul></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a name="jetty-otherserver.xml"></a>Example Other Server XML</h4></div></div></div><p>The following example creates another server instance and configures it with a connector and deployer:</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><?xml version="1.0"?><!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd"> |
