LaunchClojureRepl.java

// you will need the clojure jar AND the org.clojure.tools.nrepl jar for this
import clojure.java.api.Clojure;
import clojure.lang.IFn;
import clojure.lang.RT;
import clojure.lang.Keyword;

public class LaunchClojureRepl {
  public static void main(String[] args) {
    IFn require = Clojure.var("clojure.core", "require");
    require.invoke(Clojure.read("clojure.tools.nrepl.server"));
    IFn server = Clojure.var("clojure.tools.nrepl.server", "start-server");
    Keyword port = Keyword.intern("port");
    server.invoke(port, 12345);
  }
