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.
Torsten
