hello,

i have a message like this

0200623A400108C180000605350138000009011209450656381209450901090260120300800000006563815007110200900100800000012534316522301360

and what i expected is like this

    Bit-2 = 053501 
    Bit-3 = 380000 
    Bit-7 = 0901120945 
    Bit-11 = 065638 
    Bit-12 = 120945 
    Bit-13 = 0901 
    Bit-15 = 0902 
    Bit-18 = 6012 
    Bit-32 = 008 
    Bit-37 = 000000065638 
    Bit-41 = 15007110 
    Bit-42 = 200900100800000 
    Bit-48 = 534316522301 
    Bit-49 = 360

and this is some snipped code to test and packager

String inHex = "0200623A400108C180000605350138000009011209450656381209450901090260120300800000006563815007110200900100800000012534316522301360";

        GenericPackager pkgr;
        ISOMsg m = new ISOMsg();

        try {
            pkgr = new GenericPackager("...base1.xml");
            Logger l = new Logger();
            l.addListener(new SimpleLogListener());
            pkgr.setLogger(l, "");
            m.setPackager(pkgr);
            m.unpack(ISOUtil.hex2byte(inHex));
         //   m.dump(System.out, "");

        }

        catch (ISOException ex) {

            ex.printStackTrace();
            m.dump(System.out, "");

        }

I am not 100% sure but this may be the problem

Hexdump of the hex2byte message

0000  02 00 62 3A 40 01 08 C1  80 00 06 05 35 01 38 00  ..b:@.......5.8.
0010  00 09 01 12 09 45 06 56  38 12 09 45 09 01 09 02  .....E.V8..E....
0020  60 12 03 00 80 00 00 00  65 63 81 50 07 11 02 00  `.......ec.P....
0030  90 01 00 80 00 00 01 25  34 31 65 22 30 13 60     .......%41e"0.`

if you notice
03 00 80 offset 0x22 - 0x24

 <isofield
      id="32"
      length="11"
      name="ACQUIRING INSTITUTION IDENT CODE"
      class="org.jpos.iso.IFB_LLNUM"/>

Indicate length is 3 and value is 008 and a nibble of value 0 left over.

03 00 80 00 00 00  65 63 81

Field 37 is 
  <isofield
      id="37"
      length="12"
      name="RETRIEVAL REFERENCE NUMBER"
     pad="true"
      class="org.jpos.iso.IFB_NUMERIC"/>

And you are expecting the nibble left over from field 32 to be used in field 37 and I dont think that will happen as we use byte boundaries.

Can anyone confirm this?

have you try ISO87APackager ? or its the iso87ascii.xml if you look in the jpos.jar in the packager folder.

here is my code, and there is no error

ISOMsg isoMsg = new ISOMsg();

isoMsg.setPackager(new ISO87APackager());

isoMsg.unpack(msg.getBytes());

printISOMessage(isoMsg);

System.out.println(ISOUtil.hexdump(msg.getBytes()));

}

}

} catch (ISOException e) {

e.printStackTrace();

}

hope this will help you

hai mark...as suggestion from galih i just modified my test class and pick iso87ascii.xml file from jpos.jar like this

String inHex = "

0200623A400108C180000605350138000009011209450656381209450901090260120300800000006563815007110200900100800000012534316522301360"

;


        GenericPackager pkgr;
        ISOMsg m = new ISOMsg();

        try {

pkgr = new GenericPackager("..\\iso87ascii.xml");

            Logger l = new Logger();
            l.addListener(new SimpleLogListener());
            pkgr.setLogger(l, "");
            m.setPackager( pkgr);

m.unpack(inHex.getBytes());

            m.dump(System.out, "");

        }

        catch (ISOException ex) {

            ex.printStackTrace();
            m.dump(System.out, "");

        }
