Creating an ISO8583 Client using jPOS Q2
Creating an ISO8583 Client using jPOS Q2 is really simple compared to Spring Integration or Netty. Unlike both Spring Integration or Netty, jPOS is specialized messaging with ISO 8583 format. There are a bunch of utility classes and modules we can use, but please read the jPOS licence before you decide to use jPOS for commercial usage. Ok, let’s start with the purpose of this tutorial, we are going to create an ISO8583 Client using jPOS Q2 . Basically all we need to do is create a mux and channel configuration, but we should know what happens when we send a request and receive a response.
