So, this started when I read Keith Swallow's article on a simple web server:
http://keithcelt.com/a-simple-web-server-in-clojure I took his code and ran "lein new" to create a new project and I copy and pasted his code to core.clj and made some minor adjustments, adding gen-class and main so I could run this from the command line. My main function looked like this: (defn -main [& args] (let [port (Integer/parseInt (first args))] (println "Server is starting") (run-server port echo))) Which called his function: (defn run-server [port service] (let [server-socket (create-socket port)] (while (not (. server-socket isClosed)) (listen-and-respond server-socket service)))) I compiled that and ran "lein uberjar" and then ran it from the command line and it worked great. Then, to make it slightly more flexible, I wanted to hand in the name of the service from the command line. So I made a minor change: (defn run-server [port what-to-do] (let [server-socket (ServerSocket. "localhost" port)] (while (not (. server-socket isClosed)) (listen-and-respond server-socket what-to-do)))) (defn -main [& args] (let [port (Integer/parseInt (first args)) service (second args)] (println "Server is starting") (println "port: " port) (println "service: " service) (run-server port service))) I compiled this and ran it. And now this line: (defn run-server [port what-to-do] Gets this error: Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Number at who_is_logged_in.core$run_server.invoke(core.clj:27) I'm calling it from the command line with: java -jar who-is-logged-in-1.0.0-SNAPSHOT-standalone.jar 3456 who-is-here-now I also tried putting the service name in quotes: java -jar who-is-logged-in-1.0.0-SNAPSHOT-standalone.jar 3456 "who-is-here-now" Can anyone tell me what is wrong? Why does Clojure think I'm trying to cast "who-is-here-now" to a number? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
