Determining which packager to use?

[OmexIT]

Please guide on which packager to use because the server i am communicating with expects this kind of message:

03631200Ώ0?☺ ϊΑ ♦ 16639642006000650801100000000000010030000000001605062012112010345320121120200066

The message should contain ascii part that describes the fields present......

I am using:

 GenericPackager packager = new GenericPackager("basic.xml");

But the problem is that it does not produce that kind of message

[chhil]

What does your basic.xml looks like?
How did you decide the field formaters in your custom packager?did you follow a spec or its based on the raw message provided?
What errors did you get while using it?

On a lighter note, try renaming basic to complex and it might just work :-).

Not very helpful or smart?

Those 'binary' characters will have gone through a number of translation
to get to our eyes, what that meant and what they might have been when
you pasted are likely very different.

Sorry, what do you mean?

This means nothing to us, basic.xml is a file on your system that
contains who knows what (apart from you).

> But the problem is that it does not produce that kind of message

You need to get the documentation of the system you want to connect to
and follow the guidance on matching the Packager (and Channel) to the
specification. This should be a one off exercise if done correctly and
in doing so you might find there is already a packager you can use,
perhaps with minor changes.

The smart question would include the ISO8583 version, the name of the
target systems perhaps, but very much more than you have presented.

Please try and do some of the work and ask a *smart* question.

I have uploaded my "basic" xml, and that was funny -:)

From the message

03631200Ώ0?☺ ϊΑ ♦ 16639642006000650801100000000000010030000000001605062012112010345320121120200066

The part "?☺ ϊΑ ♦ " is acii characters that describes present fields. First it is 64bit binary then you get the bytes and then get the ascii characters fro the bytes.

I tried creating  the following message manually using the following piece of code:

Message 00411804 0     00000012407520121008154732831

F-11 Value = 036803

F-12 Value = 121008154732

F-24 Value = 801

 00411804........00000012407520121008154732831

String s = "0000000000110000000000010000000000000000000000000000000000000000";

String s2 = "";

        char nextChar;

        int bites = 0;

        for (int i = 1; i <= 8; i++) //this is a little tricky.  we want [0, 7], [9, 16], etc

        {

            nextChar = (char) Integer.parseInt(s.substring(bites, (i * 8)), 2);

            s2 += nextChar;

            bites += 8;

        }

        String iso = "00411804" + s2 + "00000012407520121008154732831";

I f I try to unpack ISO, I get the error below:

Hi,
I am going to ignore the manual work you are doing.
Did you consider changing your bitmap packager to IFB_BINARY and not create the bitmap yourself.
You need a channel that prepends the 2 byte  length that includes te length of length.
0363 interpretted as 3x16 +63 = 111. = 107 +4
107 is length of the message "1200Ώ0?☺ ϊΑ ♦ 166396420060006508011000000000

00010030000000001605062012112010345320121120200066"
4 is the length of "0363"

The target system is called: BancsConnect

The are using  iso 8583:93 version 1.6

What ISO field class can I use so as to create 8bit ASCII for field 1?

[chhil]

Can you look at https://groups.google.com/forum/?fromgroups=#!searchin/jpos-users/bancsconnect/jpos-users/-ycMB3Sejaw/q5qp-VZz7SkJ
This is a bancsconnect thread see if it helps.

[OmexIT]

Thank you very much, the thread helped a lot. I used iso87ascii-binary-bitmap.xml with few modifications and i get what is required.

I appreciate!!
