WOServletAdaptor trouble with tomcat

Hi,

I have been trying to deploy on Tomcat a WARed application.  The issue
I get is that Tomcat logs a bunch of stuff including "- Marking
servlet WOServletAdaptor as unavailable" (see the full log below) when
I fire up the app, and that going to the app's URL
(http://localhost:8080/TestProject/WebObjects/) gives the nice  little
error page "HTTP Status 404 - Servlet WOServletAdaptor is not
available".

This only happens when my Application class extends ERXApplication and
not when it extends WOApplication.  I have tried Eclipse 3.2.2 and
3.3, upgraded WOLips, upgraded Wonder to the latest frameworks, and
made a very simple application with a Main component with simple
static HTML to make sure it was nothing else.

The interesting part is that the exception presented is, as I
understand what's "under the hood", impossible!  Specifically,
_NSUtilities.instantiateObject should only call
_NSUtilities._explainInstantiationException if arguments were passed
to the specified constructor, which WOApplication.primeApplication
does not.

Any ideas?
