How to parse a given line using jPOS?
I use this code:
import org.jpos.iso.ISOPackager;
import org.jpos.iso.packager.GenericPackager;
import org.jpos.iso.packager.ISO87BPackager;
import org.jpos.iso.ISOException;
import org.jpos.iso.ISOMsg;
import org.jpos.iso.ISOUtil;
import org.junit.Assert;
public class Utils {
public static ISOMsg ParseIsoMessage(String hexMsg) throws ISOException {
// convert hex string to byte array
byte[] bmsg =ISOUtil.hex2byte(hexMsg);
ISOMsg mes = new ISOMsg();
// set packager, change ISO87BPackager for the matching one.
mes.setPackager(new GenericPackager("resources\\packager.xml"));
//unpack the message using the packager
mes.unpack(bmsg);
//dump the message to standar output
mes.dump(System.out, "");
return mes;
}
}
102 field in
packager.xml (
copy with iso87binary.xml with one change):
<isofield
id="102"
length="28"
name="ACCOUNT IDENTIFICATION 1"
class="org.jpos.iso.IFB_LLCHAR"/>
An error is issued:
org.jpos.iso.ISOException: org.jpos.iso.IFB_LLCHAR: Problem unpacking field 102 (java.lang.ArrayIndexOutOfBoundsException: 10187) unpacking field=102, consumed=10187
at org.jpos.iso.ISOBasePackager.unpack(ISOBasePackager.java:340)
at org.jpos.iso.ISOMsg.unpack(ISOMsg.java:468)
at Utils.ParseIsoMessage(Utils.java:17)
at TestHostToHost.test0100(TestHostToHost.java:122)
Please help me figure out what the problem is. Maybe another class needs to register 55 field in packager? I tried different. How to solve this problem?

The source code of the example can be found on GitHub.

The data displayed and the rawmessage printed is not matching The rawmessage is not following the format of the packager defined. The problem could have occurred before field 102.
Inorder to debug manually u can check the bitmap positions and see of the positions are confirming to the spec.
