by the follow program
m.set (new ISOField (0, "1800"));
m.set (new ISOField (11, "101"));
m.set (new ISOField (37, "a"));
m.set (new ISOField (60, "1234"));
System.out.println(ISOUtil.dumpString(b));

resule is : 18000020000008000010000101a 0041234

but when i try to unpack error happen:
org.jpos.iso.ISOException: field packager '24' is null
at org.jpos.iso.ISOBasePackager.unpack(ISOBasePackager.java:230)
at org.jpos.iso.ISOMsg.unpack(ISOMsg.java:342)

and when

GenericPackager p = new GenericPackager("base1.xml");
InputStream in = new FileInputStream(visamsg.DAT");
int nbytes = in.available();
// Read in input file and strip any training white space
byte[] hexbytes = new byte[nbytes];
in.read(hexbytes, 0, nbytes);
while (Character.isWhitespace((char) hexbytes[nbytes - 1]))
nbytes--;
// Convert it to a byte array
byte b[] = ISOUtil.hex2byte(hexbytes, 0, nbytes / 2);
// And upack it into an ISOMsg
ISOMsg msg = new ISOMsg();
msg.setPackager(p);
msg.unpack(b);
error is:

how can i do to parse :18000020000008000010000101a 0041234

thanks!

What on earth are you trying to do?

What are you trying to unpack?
The result of the pack or something else?
From the code given below, can I assume you are also converting the
String into a byte array using ISOUtil.hex2byte and then the unpack of
the byte[] is failing?

If so, I would expect that as you have damaged the message entirely!

You should not throw anything away, spaces have just as much right to be
at the end of a message as any other character. You should take care to
preserve the whole message and not add (spaces) or take anything away.

Why do you want to do this conversion? Unless you are saving the
character message in a hex format, this breaks it.

You are failing to distinguish between character and hex and getting
yourself very confused. Take a deep breath and check what you are
trying to do please?

msg.unpack("18000020000008000010000101a 0041234".getBytes());

might do what you need, but I am not certain, as it is not obvious to me
what you are trying to achieve.

You have a header of size 9 setup in your packager.

Set the header and "this" problem will go away.

I missed the header completely, but think that will only take effect at
the Channel level?

I do think unnecessary hex conversions are causing the problems.

Ya..I should have been more specific about "this" ;)... it will fix the ISOException

Oops ... I did it again ;)

field packager '24 is due to the was field 60 (the one with a bitmap is being used).

.ArrayIndexOutOfBoundsException:Is due to the header.

We have this support for headers at the packager level too, I think
using headerLength="9" is looking for trouble here.
