That's the right way to do it, IMO. Better yet, write a Java wrapper
to offer Javadocs and to hide any interop code. That means extra work
on both ends, but in Java shops Clojure-

Hi,
It was recommended in the past to go through the clojure side of things.
That means for me to call hash-map rather than RT.map. By creating a small
helper class one can get one's own Clj.map while still going through the
official API as recommended. Hence I didn't mention RT.map.

Hi,
You can also do it the other way around, use gen-class
and write yourself a static entry point callable from Java.
You get all the Clojure runtime init stuff done and you can define your
dependencies in
the clojure file (require or use). Then you can dive into the Clojure world for
as long
Just skimming this on the phone, has no one mentioned RT.map?

Hi Meikel,Ken
Thank you so much for taking the time to reply to my question. Meikel
Thanks for the code. I will implement as described above.

Hi Eamonn,
if you find this too tedious to write and use it quite often, then there is
always the possibility to hide things a little bit behind a facade.
class Clj {
static final Var seqVar = RT.var("clojure.core", "seq");
static final Var keywordVar = RT.var("clojure.core", "keyword");

Syntactically invalid Clojure code would fail just as much in Clojure

Hi Meikel
Thank you for your reply. Is there a way to populate the HashMap
before passing it to the invoke method
I tried the following
Var keyword = RT.var("clojure.core", "keyword");
Var hashMap = RT.var("clojure.core", "hash-map");
hashMap.invoke(keyword.invoke("a"), 1);
then I created the fo

This does not pass a map to the function, but the string "#{:a 1 :b 2}". And

The problem could be that #{} in clojure is a set literal, try using

Hi
I'm new to Clojure so forgive me if this is a dumb question. I want
to incorporate some Clojure into a Java application.
String rule="(str key val label)";
String str = "(ns test) " + "(defn foo [key val label] " +
