Hi,

I'm new to both abcl and java. I was wondering if someone could provide a "hello world" example (the more details the better) where I write the program in java, create a jar file, and then use that from the repl? An example of what I'd like to do using Clojure is (see http://pramode.net/clojure/2010/05/01/clojure-java-interop/ ):

1) counter.java:

package demo public class counter{ int c = 0; public void increment() { ++c; } public int get() { return c; } public static int sqr(int x) { return x*x; } }

2) Using in Clojure:

; To get this to run in SLIME do the following (where we're in demo/ to start):

;; ;; > javac counter.java ;; > cd ../ ;; > jar cvf demo.jar demo ;; > mv demo.jar lib/ ;; ;; Remember we were in demo/ to start. The directory lib/ is created when we ;; run lein new. So now we have the jar file we created placed with all of the

;; other jar files on the classpath. So we can continue: ;; ;; > lein swank ;; ;; Now start up emacs and M-x slime-connect (accepting 127.0.0.1 and 4005 defaults). ;; At the repl in emacs do ;; ;; user> (import '(demo counter))

;; user> (counter/sqr 4)

Thanks, I really appreciate any help!
