Re: [armedbear-devel] Calling java from lisp

OK. I can see where my first error lies: jcall parameters are incorrect. Here is a corrected version:

(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 nil fmtstring args)))

But this does not work yet as I do not know how to convert a lisp list to a java array. IS there any utility function or should I do it "by hand" ?

JAVA:JNEW-ARRAY-FROM-LIST should be what you want.
