Example Java static for calling Clojure functions

InvokeClojure.java

import clojure.lang.IFn;
import clojure.lang.RT;

public class Clojure {

    public static Object invokeCLJ(String ns, String fn, Object... args) throws NoSuchMethodException {
        clojure.lang.Compiler.eval(RT.readString("(require '" + ns + " :reload-all)"));
        clojure.lang.IFn f = (IFn) RT.var(ns, fn).deref();
        if (f == null) {
            throw new NoSuchMethodException("Could not find " + fn + " in " + ns + " or could not load " + ns);
        }
        return f.applyTo(RT.arrayToList(args));
    }
}
