<title>Jetty 8.1.x Adapter</title>
<para>
Keycloak has a separate adapter for Jetty 8.1.x that you will have to install into your Jetty
installation. You then have to provide some extra configuration in each WAR you deploy to
Jetty. Let's go over these steps.

<para>
There is a adapter zip file for Jetty 8.1.x in the <literal>adapters/</literal> directory in the Keycloak appliance
or war distribution. You must unzip this file into Jetty 8.1.x's root directory. Including
adapter's jars within your WEB-INF/lib directory will not work!

Enabling Keycloak for your WARs is the same as the Jetty 9.x adapter. Our 8.1.x adapter supports both keycloak.json
and the jboss-web.xml advanced configuration. See <link linkend="jetty9_per_war">Required Per WAR Configuration</link>
