What packager is being used on the server?

Your packager and the servers packagers are not aligned (definition of field x om your ISO8583 does not match definition of fied x on the server) causing the parsing to fail on the server.

What should I do?

Align the packagers.

How do I align them?

Get the packager from the server and go field by field and manually align them in your custom packager.

Can you help align them?

Your custom packager is something you will need to debug and fix on your own, its not jpos related. You may want to define the bitmap and field priors to 4 that you have not done in your custom packager. When you use any code, do try to understand it before using it.

You can use the jpos packager which you know work but can't use to pack the message, get the bytes/hexdump and compare it wit you are sending and understand why the server does not like your custom packaged message.

..the MTI is not showing the correct value, and all the fields are not giving me the correct values been assigned to them.

just like @chill said It's a misalignment of your packager field definitions. Go field by field to make sure you have defined it correctly here

NOTE: I am not using a JPOS packager, but i am making use of a JPOS channel...and, i have my code up there (the only change i made up there..is to add my fields from 0-the last.

I will probably need an explanation for this please, so i can know the things to do and the things not to do.

1. Stop.
2. Learn how to reply to a post, maintaining quoted portions so we can see what you are asking and what you are not
I appreciate google reply editor doesn;'t help here but you could/should be able to do better please.
3. Learn posting etiquette - trim your posts
4. Read http://www.catb.org/esr/faqs/smart-questions.html - this advise is long overdue.

This is not a challenge you need to share here, please take the advice already given and use it.

Here it is wrong, this should very likely be 0800 ...

... it pushes all the rest of the data out, but manages to complete the parse - you got 'lucky'

5. Get your specification and read it.

6. Have your reply code check the MTI - for validity and so you know what you are replying to, instead of trying to echo back a poorly formed MTI in your reply...

7. Perhaps time to form a Israels.'j'POS mailing list for more on topic discussions about your code and your interfaces to jPOS, then we can discuss jPOS here and you can please continue to keep your code to yourself.

:-)

8. If you really want to reinvent the wheel, then please feel free, but also feel free to keep it to yourself and to please keep the topics here directly related to jPOS.

Thanks

Try using the attached file.

I fixed your field alignments for the few fields involved in the message you are sending (I am assuming you are talking to a postilion system). 

If unpacking of the response doesn't work fix it yourself.

If it doesn't work, discard this attachment and continue trying to understand how ISO messages work and how fields are packed.

Looks like you can't debug your own packager or understand how to configure your packager with instructions on how the fields are supposed to be.

Hopefully my last Off Topic response here.

Thanks so much for your time @chill, i really appreciate...I have been able to rectify it, sending and getting my required response from the postilion system.

whenever i see your post, i know there will definitely be an answer somewhere.

Everything is solved already. (helping me to shortening the long JOURNEY already :) :) thanks.).

You are welcome.

I hope you realize that your questions are not jpos related and this is NOT the forum/group to ask them. 

You will probably not get a response to off topic queries in the future.

You should try stackoverflow.com or talk to the guys of the system you are interfacing to, for assistance.

Try to understand what you are doing, try to understand the code you are using, be professional about it.

I wish you the best with your project.

I can now use JPOS on my Android device, by having to make use of some JPOS packages..without the Q2..which was giving me a little challenge....., I now have a smooth connection... :) :)

Thanks to you all in here....I really appreciate.
