I'm not sure what is causing this either, and the stack trace starts pretty deep
inside the Cocoon processing hierarchy. A couple of notes that might help
investigate:
* This particular error message appears to be generated by
Cocoon, not Tomcat. I cannot find such an error message text
in Tomcat's message files (or Strings in the code).
* One thing guaranteed to cause problems would be an attempt
to load a "javax.servlet.http.HttpServletRequest" class from a
JAR file underneath WEB-INF/lib (or from an unpacked class
under WEB-INF/classes). Tomcat disallows such an attempt
to override one of the standard API classes.
