Can you post your geronimo-web.xml?  It sounds like maybe some
elements are out of order or have the wrong namespace.  Or, if you
have an XML Schema validation tool or function in your IDE you might
try validating your geronimo-web.xml against the geronimo-tomcat
schema in the schemas/ directory of your Geronimo tree.



I've tried shuffling the resource-ref around... should I be declaring it 
differently?


Here's my geronimo-web.xml:
