So you have to compile the namespace. See http://clojure.org/compilation. Then you have to a colon in the ns-clause: :gen-class instead of gen-class. And finally you have to 'use' your namespace if you want to call the clojure function: (in-ns 'user) (use 'some.Example). Or you have to use the dot notation for the method calls. (.toString (some.Example.)). However for this you have to compile the class with 'compile'. Note: ns is used only to setup a namespace. So it should be called only once. To switch namespaces in the Repl use in-ns. Since the repl sets up user for you, you shouldn't use ns.
