Issues with ring

[noprompt]

The driver seems to cause problems when using ring with versions >= 1.4.1.

Here are the exact steps I took to produce the problem.

$ lein new compojure foo

The project file:

(defproject foo "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :dependencies [[org.clojure/clojure "1.4.0"]
                 [factual/factual-clojure-driver "1.4.5"]
                 [compojure "1.1.5"]]
  :plugins [[lein-ring "0.8.2"]]
  :ring {:handler foo.handler/app}
  :profiles
  {:dev {:dependencies [[ring-mock "0.1.3"]]}})

Attempt to start the server:

$ lein ring server

Edit: Versions >= 1.4.1

A workaround for now is to use version 1.3.1 of this driver, i.e.:

[factual/factual-clojure-driver "1.3.1"]

You could also consider using factql, which is a DSL approach to using Factual (and currently uses version 1.3.1 of this driver).

There seems to be a conflict in the slf4j versions being included. Do avoid this, please try the following: [factual/factual-clojure-driver "1.4.5" :exclusions [org.slf4j/slf4j-log4j12]]

[noprompt]

Thanks. I'll give that a shot!

[yoshimotob]

There is also a new driver version up that should resolve this automatically: [factual/factual-clojure-driver "1.4.6"] Let us know if this will work for you as well. Thanks!

[noprompt]

Even better! I'll be working on the app that uses this driver again tomorrow and will be sure to let you know. Thanks again for your help.

My apologies for the late response. I do want to verify that [factual/factual-clojure-driver "1.4.6"] works like a charm! Awesome work guys.
