Re: [jpos-users] jpos + POS Terminal

[Victor Salaman]

Hi:

First, without getting into the details, do you have all the required documentation to embark on this project? You'll need to know:

* What type of POS is it? 

* Do you have documentation from the POS vendor?

* The physical protocol the POS in talking so you can match your channel accordingly.

* Does the protocol have some sort of header?

* Is your packager really 'iso87binary'?

My advise for you: 

* Get POS vendor documentation

* Please buy the jPOS programmer's guide ($50.00)

* Read more until your answer the four questions below by yourself :)

You have a long but interesting path ahead of you,

hi all ,

i am  trying to build the simulator for acquirer & issuer system using jpos . 

Steps i followed :

I made transaction in POS terminal  - (Master Card) , I changed the Terminal Host ip and port to , JPOS Server ip and port (packager - iso87binary.xml).

I recieved exception as like this in JPOs server log

And Communication Error in POS Terminal ...

Whether i am in right way ...

---------------------------------------------------------------------------------------------------------------------------------------------

My questions :

1. Is it possible to parse the message , that is sent from POS Terminal that i connected to my PC , and trying  to receive the message using the JPOS Server that runs in my pc (locally )
2. Do i need the payment network something like that , Because i am only  trying to simulate acquirer system and issuer system.
3. Is this possible to implement in JPOS +  connecting to real terminal and get the messages and parsing it ..
4. If so any guidance will be more thankful .
