So the only dependencies your plan is declaring are on catalina,
catalina-cluster, and wnode JARs?  I don't see anything on that list
indicating that the Servlet API should be included on the class path.

I think you have two choices -- one is to add the servlet API JAR as a
dependency, and the other is to add a dependency on a module such as
geronimo/tomcat/*/car which would already have the servlet API on its
class path.

Thanks,
