;;; Commentary:
;; Currently this only supports the external compilation and execution
;; of java code blocks (i.e., no session support).
;;; Code:
(require 'ob)
(require 'ob-eval)
(defvar org-babel-tangle-lang-exts)
(add-to-list 'org-babel-tangle-lang-exts '("java" . "java"))
(defvar org-babel-java-command "java"
"Name of the java command.")
(defvar org-babel-java-compiler "javac"
"Name of the java compiler.")
(defun org-babel-execute:java (body params)
(let* ((classname (or (cdr (assoc :classname params))
(error
"Can't compile a java block without a classname")))
(packagename (file-name-directory classname))
(src-file (concat classname ".java"))
(cmpflag (or (cdr (assoc :cmpflag params)) ""))
(cmdline (or (cdr (assoc :cmdline params)) ""))
(full-body (org-babel-expand-body:generic body params))
(compile
(progn (with-temp-file src-file (insert full-body))
(org-babel-eval
(concat org-babel-java-compiler
" " cmpflag " " src-file) ""))))
;; created package-name directories if missing
(unless (or (not packagename) (file-exists-p packagename))
(make-directory packagename 'parents))
((lambda (results)

(org-babel-read results)
(let ((tmp-file (org-babel-temp-file "c-")))
