Woops.
I meant to have both occurrences of (rba-reverse) in defn -main
replaced with just (reverse). I made that replacement, and still get
nearly the same error message:
Exception in thread "main" java.lang.IllegalArgumentException: No
matching method found: reverse for class andy.try.ReversibleByteArray

Thanks for the suggestion. I'm not sure I implemented it
correctly. Still no joy. Here is exactly what I tried:
% ls -R
andy
./andy:
try.clj
% cat andy/try.clj
(ns andy.try
(:gen-class))
(gen-class
:name andy.try.ReversibleByteArray
:prefix rba-)
(defn rba-reverse [this]
(println "In rba-reverse"))
(defn -main [& args]
(let [N (. Integer valueOf (nth args 0) 10)]
(println "N=" N)
(let [buf (new andy.try.ReversibleByteArray)]
(println "(class buf)=" (class buf))
(println "(. buf (rba-reverse)) returns " (. buf (rba-
reverse))))))

(ns try

Try using a two-component (or more) namespace name. I think gen-class
in a one-component namespace will try to create the class in the
default package, which Java does not like.
