| different ports/connectors. The simplest way to do this is to create |
| multiple <code class="code">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>How to create multiple server instances is simply done when writing |
| embedded 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 your servers in XML. The id field in the Configure element of |
| jetty.xml files is used to identify the instance that the configuration |
| applies to, so to run two instances of the Server, you can copy the |
| jetty.xml, 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 jetty.xml 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" type="disc"><li class="listitem"><p>Change all id="Server" to the new server |
| name:<code class="literal"><Configure id="OtherServer" |
| class="org.eclipse.jetty.server.Server"> </code></p></li><li class="listitem"><p>For all connectors for the new server change the refid in the |
| server argument: <code class="literal"><Arg name="server"><Ref |
| refid="OtherServer" /></Arg></code></p></li><li class="listitem"><p>Make sure that any references to properties like jetty.http.port are |
| either renamed or replaced with absolute values </p></li><li class="listitem"><p>Make sure that any deployers AppProviders refer to a different |
| "webapps" directory so that a different set of applications are |
| deployed.</p></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 |
