[jetty-users] Drools Guvnor under Jetty?

Hi all, 

I've been trying to deploy an app called Guvnor (version 5.5.0, http://www.jboss.org/drools/drools-guvnor.html) under Jetty 8, which is built/tested to run under JBoss.  I'm running into the following stack trace on startup:

Here's what I've tried so far to fix this, based on Googling around and reading through other folks' attempts to deploy apps relying on WELD under Jetty: 

1) adding the following to Guvnor's web.xml: 

<listener> <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class> </listener>

2) creating jetty-env.xml inside Guvnor's WEB-INF with these contents: 

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" 
    "http://jetty.mortbay.org/configure.dtd">

<Configure id="webAppCtx" class="org.mortbay.jetty.webapp.WebAppContext">
  <New id="BeanManager" class="org.mortbay.jetty.plus.naming.Resource">
    <Arg>
      <Ref id="webAppCtx"/>
    </Arg>
    <Arg>BeanManager</Arg>
    <Arg>
      <New class="javax.naming.Reference">
        <Arg>javax.enterprise.inject.spi.BeanManager</Arg>
        <Arg>org.jboss.weld.resources.ManagerObjectFactory</Arg>
        <Arg/>
      </New>
    </Arg>
  </New>
</Configure>

The app does technically deploy with these additions, but I get the stack trace above and the Guvnor UI just shows a "fatal error" message.  Any hints on what I need to do? 

Thanks
