Hi all, I've been trying to deploy Guvnor 5.5.0 under Jetty 8, but I'm running into the following stack trace on startup: ERROR 27-06 04:13:58,475 (JettyPost72Container.java:initialize:72) Unable to create JettyWeldInjector.

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 &quot;-//Mort Bay Consulting//DTD Configure//EN&quot; &quot;http://jetty.mortbay.org/configure.dtd&quot;> <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?
