Hi
I have our own jdbc driver when I am trying to use clojure java.jdbc it is 
giving me error like below

Exception in thread "main" java.lang.ClassCastException: 
a.b.my_custom_driver cannot be cast to clojure.lang.IFn
at clojure.gemfireXD.jdbc$createStatement.invoke(client.clj:13)

at clojure.lang.AFn.applyToHelper(AFn.java:161)
at clojure.lang.Var.applyTo(Var.java:532)
at clojure.main.main(main.java:37)


When I tried following 



(ns clojure.custom.jdbc
  (:import [java.sql Connection DriverManager])
  (:require [clojure.string :as clojure-string]))

(defn getConnecton
  [url]
  (clojure.lang.RT/loadClassForName "custom.url.ClientDriver") 
  (DriverManager/getConnection url))

(defn createStatement
  [db]
  (^Statement (.createStatement db)
  ))
  

(createStatement((getConnecton "jdbc:mydbServer://localhost:1527/")))

Exception in thread "main" java.lang.ClassCastException: 
my.custom.implementation.internal.ConnectionCustom cannot be cast to 
clojure.lang.IFn
