Hello, I'm using the following code to execute a Lisp function: #+BEGIN_SRC java public class Call { public static void main(String [] args) { Call thisObject = new Call(); Interpreter interpreter = Interpreter.createInstance(); interpreter.eval("(load \"lispfunctions.lisp\")"); org.armedbear.lisp.Package defaultPackage = Packages.findPackage("CL-USER"); Symbol voidsym = defaultPackage.findAccessibleSymbol("SAY-HELLO"); Function voidFunction = (Function) voidsym.getSymbolFunction(); LispObject result = voidFunction.execute(new JavaObject(thisObject)); } } #+END_SRC The Lisp side: #+BEGIN_SRC lisp ;;; lispfunctions.lisp (java:add-to-classpath "/opt/abcl-bin-1.4.0/abcl-contrib.jar") (require :jss) (defun say-hello () "Hi!") #+END_SRC It works without the (requirese :jss); whenever I try to use it I get: #<THREAD "main" {C7BBB6C0}>: Debugger invoked on condition of type SIMPLE-ERROR Don't know how to REQUIRE JSS. Any pointers? Thanks! -- fsmunoz@sdf.org SDF Public Access UNIX System - http://sdf.org
