Bad case of copy pasta?
You have am extra namespace definition:
(ns dbns
(:require [clojure.java.jdbc :as jdbc]
[mysql/mysql-connector-java "5.1.38"]))
You need to remove it, and move the require clause up in your ns:
(ns jclojure.core
(:gen-class)
(:require [clojure.java.jdbc :as jdbc]
[mysql/mysql-connector-java "5.1.38"]))
