ISO - not getting appropriate response

I have used JPOS library for creating ISO message but I am not getting any response, The call which I have initiated is SIGN-ON. The code which i have implemented and request is mentioned below.

channel.setHost("xx.xx.xx.xx", xxxxx);
       channel.connect();
       ISOMsg isoMsg = new ISOMsg();
       isoMsg.setPackager(packager);
       isoMsg.setMTI("0800");
       isoMsg.set(7, "1224190516");
       isoMsg.set(11, "120347");
       isoMsg.set(24, "001");
       isoMsg.set(70, "003");
       byte[] send_PackedRequestData = isoMsg.pack();
channel.send(send_PackedRequestData);```
Solution

  • For once, you have to set the packager to the channel and send the isoMsg object not the bytes:

    channel.setPackager(packager);
...
channel.send(isoMsg);

    Additionally I don't see you calling channel.receive();

    And if you did there are many possible reasons why you wouldn't receive a response, among others:
