How to generate an ISO message in j8583

I have text data,

PROCESSINGCODE: 000000
SYSTEMTRACEAUDITNUMBER: 000001
Cardacceptorterminalidentification:3239313130303031
Reservednational:001054455354204D45535347
Networkmanagementinformationcode:0301


I need to generate an ISO Message with bitmap fields using j8583 project.

I have tried parsing a isomesssage, but I do not know how to generate an ISO Message.

Note: I know that this can be done with jpos, but I need to do it with j8583.

I have created below program.

public static void main(String[] args) {


MessageFactory<IsoMessage> mf = new MessageFactory<IsoMessage>();
try {
//mfact = ConfigParser.createFromClasspathConfig("C:\\Users\\DHEERAJ\\workspace\\j8583.xml");

String path="C:\\Users\\DHEERAJ\\workspace\\j8583.xml";
ConfigParser.configureFromUrl(mf, new File(path).toURI().toURL());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mf.setForceSecondaryBitmap(true);
mf.setUseBinaryBitmap(true);
mf.setAssignDate(true);
mf.setTraceNumberGenerator(new SimpleTraceGenerator((int) (System.currentTimeMillis() % 100000)));
System.out.println("NEW MESSAGE");
IsoMessage m = mf.newMessage(0200);

m.setValue(3, "000000", IsoType.ALPHA, 6);
m.setValue(11, "000001", IsoType.ALPHA, 6);
m.setValue(41, "3239313130303031", IsoType.ALPHA, 16);
m.setValue(60, "001054455354204D45535347", IsoType.ALPHA, 24);
m.setValue(70, "0301", IsoType.ALPHA, 4);

m.setForceSecondaryBitmap(true);

}


I have got below output.

This output doesn't have bitmap values, and have some unwanted values at start.

Can someone please help with this?

Thanks.

The following Java code prints 0200A220000000800010040000000000000000000010240507450000013239313130303031001054455354204D455353470301, in which you can see the bitmap information.
