error while using immutant server to access page from browser

Question

$ lein new pedestal-service peddy

and then add following file to immutant folder

(ns immutant.init
  (:require [immutant.web :as web]
            [io.pedestal.http :as http]
            [peddy.service :as app]))

(web/start-servlet "/" (::http/servlet (http/create-servlet app/service)))

after that

$ lein immutant deploy peddy

and then

$ lein immutant run

immutant server stated with nrepl

but when i try to open page in browser it throws error

I am using immutant 1.1.4 and pedestal-service 0.4.0

Answer 1

This is caused by Pedestal using .getContentLengthLong(), which was added in version 3.1 of the Servlet spec. Immutant 1.x is based on JBoss AS 7, which uses version 3.0 of the spec. This means you won't be able to use Pedestal 0.4.0 in any pre-3.1 container.
