I am upgrading from Jetty 6 to Jetty 7 and am having some trouble configuring a 
HandlerList for my server. I have boiled it down to the most simple 
configuration I can think of that should work, the example here: 
http://wiki.eclipse.org/Jetty/Tutorial/Embedding_Jetty#Configuring_a_File_Server_with_XML
  

I am configuring my server with this file as follows:

import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.xml.XmlConfiguration;


…

XmlConfiguration configuration = new XmlConfiguration(configFile.toURL());
configuration.configure(server);


However, I am getting the following error:

I must be doing something wrong since the main example itself doesn't even 
work. Strangely, it does not fail with this error if I do not set a 
HandlerList, but instead just add one handler:

<Set name="handler">
  <New class="org.eclipse.jetty.server.handler.DefaultHandler"></New>
</Set>


Any clues? Thanks.
