How does Q2 fit into JPOS when connecting to a banks switch?

Question

I am relatively new to JPOS and I have only used it to pack and unpack messages and I would like to understand how Q2 can help me. At the moment I am developing an application that receives requests from mPOS to a central server using REST and then I transform the messages to ISO8583 using JPOS which I then forward to a banks switch. I am supposed to maintain 1 persistent connection to the bank's switch. Can Q2 help me achieve this?

Answer 1

The question is quite broad, so it will be this answer.

I believe jPOS tutorials page is exactly what you need.

In particular the first 3:

1. Basic gateway: How to Implement a gateway from scratch
2. Customize your gateway: Adding custom code to customize it.
3. jPOS REST tutorial: How to implement a REST API interface in Q2.

Then you can use concepts of the previous 3 tutorials to build a transaction manager that process REST request to query the bank switch using ISO8583 interface
