how to encode and send ISO 8583 message with ASCII and Hexa?


i have to send a message like this :

Entete(hexadecimal)+ MTI(Ascii)+bitmap (hexadecimal)+DE11(Ascii)+DE12(Ascii)+DE24(Ascii)

so far i was using ASCIIChannel to send my ISO messages with jpos library.

here is an example of the message i would like to send (echo test).

ISOPackager packager = new GenericPackager(ISOUtils.getAbsolutePathOfAFile("./packager/iso8583packager.xml"));
    ISOMsg isoMsg = new ISOMsg();
    ISOMsg subIsoMsg = new ISOMsg();
    isoMsg.setPackager(packager);
    isoMsg.setHeader("00100101".getBytes());
    isoMsg.set("0","1804");
    isoMsg.set("1","100000000000000000000001");
    isoMsg.set("11","678897");
    isoMsg.set("12","230107100923");
    isoMsg.set("24","831");

ASCIIChannel channel = new ASCIIChannel("127.0.0.1", 5000, packager);
    //RawChannel channel = new RawChannel("192.168.1.101", 5000, packager);
    channel.connect();
    channel.send(isoMsg);

how can i do to send message with ASCII encoding and hexa ?

EDIT : here is the package used :

here is the template of the message i have to constitute (from a tcpdump):

update : the server side code (with the same packager):

@Component
public class Server implements ISORequestListener{

@Bean
public void iniTServer() throws ISOException {
    String hotname = "127.0.0.1";
        int portNumber = 5000;
        ISOPackager packager = new GenericPackager(Server.getAbsolutePathOfAFile("./packager6/iso8583packager.xml"));
        PostChannel channel = new PostChannel(hotname, portNumber, packager);
        ISOServer server = new ISOServer(portNumber, channel, null);
        server.addISORequestListener(new Server());
        System.out.println("ISO8583 server started...");
        new Thread(server).start();
}

 @Override
    public boolean process(ISOSource isoSource, ISOMsg isoMsg) {
        try {
            System.out.println("ISO8583 incoming message on host [" + ((BaseChannel) isoSource).getSocket().getInetAddress().getHostAddress() + "]");
            receiveMessage(isoSource, isoMsg);
            printISOMessage(isoMsg);
            System.out.println("ISO Message: " + isoMsg);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return true;
    }

    private void receiveMessage(ISOSource isoSource, ISOMsg isoMsg) throws ISOException, IOException, ISOException, CsvException, URISyntaxException {
        System.out.println("ISO8583 Message received...");
        InputStreamReader reader = FileUtils.loadFile("/BDD.csv", getClass());
        URL url = getClass().getResource("/BDD.csv");
        File file = new File(url.toURI());
        file.setWritable(true);
        CSVReader csvReader = new CSVReader(reader);
        //reader.close();
       List<String[]> records=csvReader.readAll();
       // Object obj=jo.parse(reader2); 
       FileUtils.csvUpdaterAtAnIndex(getClass(),csvReader, "99", "/BDD.csv", 1, 2);
        //String jsonString=gson.toJson(obj);
        //JSONObject jsonObj=new JSONObject(jsonString);
        Response resp=new Response();
        
        resp.setDataFields(IsoUtils2.buildResponseFromISOMessage(isoMsg));
        ISOMsg isoResponse=new ISOMsg();
        String response="";
        String soldeClient=records.get(1)[2];
        isoResponse=IsoUtils2.buildResponseToSend(isoMsg, soldeClient, resp);
        //System.out.println("isoResponse "+isoResponse);
        isoSource.send(isoResponse);
    }

    private static void printISOMessage(ISOMsg isoMsg) throws ISOException {
        System.out.printf("MTI = %s%n", isoMsg.getMTI());
    for (int i = 1; i <= isoMsg.getMaxField(); i++) {
        if (isoMsg.hasField(i)) {
            System.out.printf("Field (%s) = %s%n", i, isoMsg.getString(i));
         }
        }
    }

public static String getAbsolutePathOfAFile(String relativePath){
    return Paths.get(relativePath).toAbsolutePath().normalize().toAbsolutePath().toString();
}

}


Solution

  • As detailed in the comments the OP wants the message length to be sent as two bytes in network byte order. For that, PostChannel does the job.

    This modified code should work as a proof of concept, although I would suggest using Q2 to start and configure the channel following the first two jPOS tutorials and the jPOS programmers guide section 5: Channels.

    Also, you don't need to set the bitmap field, it is generated by the packager based on the present fields.

        ISOPackager packager = new GenericPackager(ISOUtils.getAbsolutePathOfAFile("./packager/iso8583packager.xml"));
        ISOMsg isoMsg = new ISOMsg();
        isoMsg.setPackager(packager);
        isoMsg.set("0","1804");
        isoMsg.set("11","678897");
        isoMsg.set("12","230107100923");
        isoMsg.set("24","831");
    
        ISOChannel channel = new PostChannel("127.0.0.1", 5000, packager);
        channel.connect();
        channel.send(isoMsg);
    

    You'll also need to configure the bitmap as binary in the packager:

      <isofield
              id="1"
              length="16"
              name="Bitmap"
              class="org.jpos.iso.IFB_BITMAP"/>
