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);```

Answer 1

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:
Unmatched channel/packager between client and server
Server not responding for some internal error
