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.

Seems like I can get around it....
#+begin_src emacs-lisp
(setq org-babel-default-header-args:java '((:cmpflag "-cp .")(:cmdline
"-cp .")))
#+end_src
This creates problems however, it is not needed anymore
Will try a bit more and report

The above should use standard property lines, see (info "(org)Buffer-wide header arguments")

This seems to me to be redundant with the above. No need to set these
for the language and the buffer.

Hi Eric,
AAAAAARRRRGGGHHHH.... now I remember I participated in that discussion
to replace #+BABEL by #+PROPERTY.....
that is the pitfall if you reuse stuff only once a year and heavy
development goes on in the mean time ;)
Thanks for the reminder and yeah now all works out ok.
Just as a note to myself and maybe others who read this...
#+PROPERTY: :mkdirp t
#+PROPERTY: :cmpflag -cp .
#+PROPERTY: :cmdline -cp .
This is what is needed to set the flags for the java environment
#+BEGIN_SRC text :tangle ./item1.txt
A
B
C
#+END_SRC
This blocks allow you to TANGLE files which you might need to test
your code (simulate input etc.)
The problem here... you need to TANGLE them... NOT execute them.
So now it works again. The problem was a PEBKAC...
Thanks Eric
Torsten
