我試圖做一個iso8583 pakage與j8583庫替換和我們運行的舊iso8583程序（我沒有源代碼）。數據包的生成與舊軟件生成的數據包不同。注意舊包裝中的「f」。包iso8583消息
代碼
messageFactory.setAssignDate(false);
messageFactory.setUseBinaryMessages(true);
IsoMessage isoMessage = messageFactory.newMessage(0x1804);
isoMessage.setBinary(true);
isoMessage.setBinaryBitmap(true);
isoMessage.setValue(3, "000000", IsoType.NUMERIC, 6);
isoMessage.setValue(11, "000001", IsoType.NUMERIC, 6);
isoMessage.setValue(12, "151021095555", IsoType.NUMERIC, 12);
isoMessage.setValue(24, "831", IsoType.NUMERIC, 3);
isoMessage.setValue(25, "8700", IsoType.NUMERIC, 4);
isoMessage.write(outputStream, 2);

我想你錯過了一些'setXXX（）'調用使工廠使用正確的設置。 –
