Hi Rob,
Thanks for your helpful reply. I have finally had success.

Evidently not.
So I started from fresh again, just to be certain.

This wasn't necessary in the end, in my case.

My mistake, sorry.
(I should have remembered that new requires 2 args from before.)

I added your amended code to the python script to handle a second
argument.
Aside: if anyone cuts and pastes Rob's python code from a browser,
you may have to delete the whitespace after the 6 continuation
symbols (\) or else python (V2.6) complains.
So I have got past yesterday's issues and now have a standalone jar
file.
In case, it is helpful to others, the commands that I used
(virtually the same as in your last email) were:
E:\etc\clojure\Leiningen\lein.py clean
E:\etc\clojure\Leiningen\lein.py deps
E:\etc\clojure\Leiningen\lein.py compile
E:\etc\clojure\Leiningen\lein.py jar
E:\etc\clojure\Leiningen\lein.py uberjar
:: WARNING: Not 'java -jar helloworld.jar'. D'oh!
java -jar helloworld-standalone.jar
Thanks for your time with this.
Regards,
John.
