It’s been a long time since my last post, because some freelance project and current company projects. Today someone ask me about how to create custom jPOS ISO8583 packager for financial transaction.

On this post, i wanna share about create custom jPOS ISO8583 packager using java class instead for xml. Creating custom packager is pretty easy, all we need to do is just extending ISOBasePackager abstract class, override the fld[] and creating constructor.

for example packager bellow:

package com.didikh.packager;

import org.jpos.iso.IFA_AMOUNT;
import org.jpos.iso.IFA_BINARY;
import org.jpos.iso.IFA_BITMAP;
import org.jpos.iso.IFA_LLCHAR;
import org.jpos.iso.IFA_LLLCHAR;
import org.jpos.iso.IFA_LLLNUM;
import org.jpos.iso.IFA_LLNUM;
import org.jpos.iso.IFA_NUMERIC;
import org.jpos.iso.IF_CHAR;
import org.jpos.iso.ISOBasePackager;
import org.jpos.iso.ISOFieldPackager;

public class MyPackager extends ISOBasePackager {

protected ISOFieldPackager fld[] = {
new IFA_NUMERIC ( 4, "MESSAGE TYPE INDICATOR"),

};

public MyPackager() {
super();
setFieldPackager(fld);
}
}

And then we can use these packager with this config:

[xml]
