Hi all, every year I want like to evaluate java snippets in org-mode to evaluate courseworks. This worked fine but recently I had a bigger data crash and re-setup my office machine. It worked ok for the crash (that is it worked ok for the set-up at that time).
I use now GNU Emacs 24.1.1 Org-mode version 7.8.11 I can evaluate simpler blocks but for more complex once I run into trouble I used #+BABEL: :mkdirp t #+BABEL: :cmpflag -cp . #+BABEL: :cmdline -cp . #+begin_src emacs-lisp (setq org-babel-default-header-args:java '((:cmpflag "-cp .") (:cmdline "-cp ."))) #+end_src ** CODE-TESTER #+BEGIN_SRC java :classname enshu4/Shop4Tester package enshu4; public class Shop4Tester { public static void main(String[] args) { System.out.println("----------Checking for list 1---------"); Shop4 shop1 = new Shop4("item1.txt"); shop1.print("potato"); shop1.printAllNames(); System.out.println("\n----------Checking for list 2----------"); Shop4 shop2 = new Shop4("item2.txt"); shop2.print("potato"); shop2.printAllNames(); } } #+END_SRC ** studentID #+BEGIN_SRC java :classname enshu4/Shop4 package enshu4; import java.util.Hashtable; import java.util.Iterator; import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.io.FileNotFoundException; public class Shop4 { private Hashtable<String, Integer> item; public void printAllNames() { String tes; Iterator<String> it = item.keySet().iterator(); while (it.hasNext()) { tes = it.next(); System.out.println(tes + " a " + item.get(tes) + "Euro"); } } public Shop4(String fname) { item = new Hashtable<String,Integer>(); FileReader fr; try { fr = new FileReader(fname); } catch (FileNotFoundException e) { System.out.println(fname + "not found"); return; } BufferedReader br = new BufferedReader(fr); String line; try { while ((line = br.readLine()) != null) { String target = line; String[] splt = target.split("="); String key = splt[0]; String val = splt[1]; item.put(key,new Integer(val)); } br.close(); } catch (IOException e) { e.printStackTrace(); } } public static void main(String[] args) { Shop4 shop = new Shop4("item.txt"); shop.printAllNames(); } } #+END_SRC If I want to execute the given source code block I end up with an error message org-babel-execute-src-block: Wrong type argument: characterp, "-cp ." I believe this is rather common due to some changes within emacs, but I can't find a way to get around this. Any idea? BTW. previous year it seems I created the lists by #+BEGIN_SRC text :tangle ./item1.txt potato=120 bread=160 milk=180 #+END_SRC but this seems not to work anymore.... anyhow that would be a minor problem Thanks for looking into this.
