resource-ref in web.xml is typically the most portable way to wire a jndi resource into a webapp, jetty-env.xml typically lets you wire in jetty specific container configuration for declaring that jndi resource inside of the webapp....personally I prefer not seeing jetty-env.xml in a webapp and let the container configure it in a context.xml or globally in a jetty.xml formatted file.
