Hello (again), I am trying to invoke java code from lisp code following http://common-lisp.net/project/armedbear/doc/abcl-user.html. Here is the code I am trying to run:
CL-USER> (defun java-format (fmtstring &rest args) (let* ((string-class (jclass "java.lang.String")) (array-of-objs (jclass "[Ljava.lang.Object;")) (method (jmethod string-class "format" string-class array-of-objs))) (jcall method fmtstring args)))
JAVA-FORMAT
And here is what I got when I try to run it:
(java-format "" "%d %08.d %s" 1 2 3)
Wrong number of arguments for public static java.lang.String java.lang.String.format(java.lang.String,java.lang.Object[]): expected 2, got 1 [Condition of type PROGRAM-ERROR]

What am I doing wrong ?
