Answer 1

I think what you're looking for is the following:

(def Clojure4Vaadin 
  (proxy [com.vaadin.terminal.gwt.server.AbstractApplicationServlet] []
    (getApplicationClass [] com.vaadin.Application)))

Have a look at the documentation of proxy.

Answer 2

The code you have given above is used to serve a webapp written in clojure via the vaadin framework. This code is meant to be run as Java Servlet as it is and the webapp logic would be in the clojure code (test.tlp), you would have to compile the servlet and package it with the clojure script in the webapp root directory.
