What does "context" file mean in jetty world

Question

I am following this tutorial instruction: http://www.eclipse.org/jetty/documentation/current/spnego-support.html

It says the following: A corresponding UserRealm needs to be created either programmatically if embedded, via the jetty.xml or in a context file for the webapp.

Now I am using embedded jetty and I could create a web.xml using the WebAppContext and \jee but what is the context file? Is it talking about something like a Spring context?

(I am fairly new to Java)

With context file for the webapp, they probably mean the jetty.xml configuration file, which can also be used on a per-app basis, when you name it jetty-web.xml and place it in your WEB-INF directory (alongside the web.xml configuration file).

Frame of a jetty-web.xml:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
    <!-- configuration here -->
</Configure>

You can configure your realms with it, e.g.:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/test</Set>
  <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/test</Set>
  <Get name="securityHandler">
    <Set name="loginService">
      <New class="org.eclipse.jetty.security.HashLoginService">
            <Set name="name">Test Realm</Set>
            <Set name="config"><SystemProperty name="jetty.home" default="."/>/etc/realm.properties</Set>
      </New>
    </Set>
  </Get>
</Configure>

Since you are using embedded jetty, I am unsure if you can configure user realms using the normal jetty-web.xml configuration, or if you have to set them up programmatically.

I did this programmatically, but with an older (6.1) version of Jetty. But I also have used the jetty-web.xml in an embedded jetty to configure some parameters, e.g. the upload file size limit.
