How to build the war file for a Clojure Noir Web application?

Question

I was able to use these commands to generate and run a sample web app from instrcution on this web site

https://github.com/ibdknox/lein-noir

lein new noir my-project-name
lein run

( I am using Leiningen 2.0.0-preview10 on Java 1.7.0_09 Java HotSpot(TM) Client VM )

The starter web app does run ok but I want to generate the war file which I can deploy manually to my application server (Websphere).

What command or configuration for Leingen 2 is needed to generate a war file for a Noir project?

To clarify, this command "lein new noir webpoc2" generate a noir project with this .clj file

(defproject webpoc1 "0.1.0-SNAPSHOT"
            :description "FIXME: write this!"
            :dependencies [[org.clojure/clojure "1.4.0"]
                           [noir "1.3.0-beta3"]]
            :main webpoc1.server)

If I add Ring to the cl file

:ring {
                   :handler webpoc1.server/handler

}

, and run lein ring uberwar, I get this :

Exception in thread "main" java.lang.RuntimeException: No such var: webpoc1.server/handler, compiling:(

Since I am new to Noir (and Clojure), I am at a loss trying to figure this out

Answer 1

Answering my question/ documenting my travails in leingen noir ring dependencies for other newbies. You may generate a noir project with "lein new noir ... " command , but update these files as follows if you want a war file .

project.clj

(defproject noir3 "0.1.0-SNAPSHOT"
            :description "FIXME: write this!"
            :dependencies [[org.clojure/clojure "1.4.0"]
                           [noir "1.3.0-beta10"]
                           [hiccup "1.0.2"]
                           [cheshire "4.0.3"]
                           ]
            :plugins [[lein-ring "0.7.5"]]
            :ring {:handler noir3.server/handler}            

            :main noir3.server)

server.clj

(ns noir3.server
  (:require [noir.server :as server]))

;;(server/load-views-ns 'noir3.views)

(server/load-views "src/noir3/views/")


(def handler (server/gen-handler {:mode :dev
                                  :ns 'noir3}))

(defn -main [& m]
  (let [mode (keyword (or (first m) :dev))
        port (Integer. (get (System/getenv) "PORT" "8080"))]
    (server/start port {:mode mode
                        :ns 'noir3})))

Then , run the following

1. "lein run" (check if your pages are accessible),
2. "lein ring server" (check if your pages are accessible),
3. and finally "lein ring war" -- you should see as war file in target dir

Answer 2

Have you declared the handler in webpoc1.server which you are referencing? Something like this:

(def handler
  (server/gen-handler {:mode :prod
                       :ns *ns*}))
