WebLogic writes to a text file and an applet reads the text file

Question

Hi there,
I need some help here!
I have an applet that needs to read from a text file:
final URL prtDataURL = new URL("http://" + getCodeBase().getHost() + ":" + getCodeBase().getPort() + "/ESTC/lib/prtDataFile.txt");
            final URLConnection urlConn = prtDataURL.openConnection();
            urlConn.setUseCaches(false);
            urlConn.setDoInput(true);
            urlConn.setDoOutput(false);
            final InputStreamReader is = new InputStreamReader(urlConn.getInputStream());
            final BufferedReader in = new BufferedReader(is);
            String inputLine;
            while ((inputLine = in.readLine()) != null){
                String[] tmp = inputLine.split("§");
                this.dateTime = tmp[0];
                this.quanTot = Integer.parseInt(tmp[1]);
                this.quanSco = Integer.parseInt(tmp[2]);
                this.quanSef = Integer.parseInt(tmp[3]);
                this.valTot = Double.parseDouble(tmp[4]);
                this.valSco = Double.parseDouble(tmp[5]);
                this.valSef = Double.parseDouble(tmp[6]);
            in.close();
            is.close();and this is ok.
Now I have the web server (WebLogic) that must write, at regular time intervals, to that file (prtDataFile.txt). The web application writes to the file (which belongs to the application).
I've tried open the file with the File object but since the war file is unexploded I can't get the real path!
I've tried open an url connection,
final URL url = new URL("http://10.191.33.249:16801/ESTC/lib/prtDataFile.txt");
final URLConnection connection = url.openConnection();
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setDoInput(false);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(currentDate + "§" + quantTot + "§" + quantSco + "§" + quantSef + "§" + valTot + "§" + valSco + "§" + valSef);;
out.flush();
out.close();which seems a little stupid since I'm opening an URLConnection to the same place where the application is. Anyway it doesn't work, i.e., it doesn't write to the file but it doesn't gives me any errors or exceptions.
Is there another way to get this two pieces communicating?
Thanks in advance

I have almost the exact same problem, and I am in the same situation as you are with respects to the language.
I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
My method:
debug = new Label() ;
debug.setLocation( 20, 20 ) ;
debug.setSize( 500, 15 ) ;
add( debug ) ;
// output
try
     OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
     byte[] buffer = { 1, 2, 3, 4, 5 } ;
     file.write( buffer ) ;
     file.close() ;
} catch( Exception e )
     debug.setText( e.toString() ) ;
     Can anyone tell why this isnt working?
