There is no "kawa-2.9".  The kawa-2.0.jar that I released
does include gnu/kawa/servlet/KawaServlet.class.  Are you using
some other kawa-XX.jar?  Did you build it yourself?  If so, how?

The --servlet option doesn't do anything without -C, so that makes sense.

Note that you also need the servlet-api.jar (available various places including Tomcat
or Glassfish).  This containss javax/servlet/http/HttpServlet.  However, if you had
gnu/kawa/servlet/KawaServlet but were missing javax/servlet/http/HttpServlet you'd get:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet

So I'm assuming there is a problem with your Kawa installation.
