Compojure
Hi list,
I'm trying to get a simple hello world Compojure application
running. I attach both the clj file and maven pom.xml (using
NetBeans+Enclojure). When I run (guestbook.core/-main), I get a blank
page in browser, no matter the URL. What am I missing?
BTW, by blank I really mean blank. If I view the page source in
Firefox, it's empty.
TIA,

Try the following instead (just modified your attached source)
(ns guestbook.core
(:use compojure.core)
(:require [compojure.route :as route])
(:require [ring.adapter.jetty :as jetty])
(defroutes dispatcher
(GET / [] h1Hello, world/h1)
(route/not-found bRequested resource not found/b))
(defn -main [ args]
(jetty/run-jetty dispatcher {:port 8080}))
It works. Strange gotcha.
You don't need the gen class or the servlet stuff. Also note that
there is a compojure google group that you can join to ask more
specific compojure based questions on. If you want to see more
examples I have some on github at http://github.com/abedra/clojure-web.
Oh, I didn't know about the Compojure group.Just joined it.
Also nice tutorials for a person like me. Lately, I've been wandering
around Clojure corners with no fruit. I plan to write a business suite
with Clojure and I think web programming is a good starting point for my
case. The tutorials show me what I want to see: how to build web apps
step by step.
Thank you for the assist and hints Aaron. Much appreciated.
