Run the neaPay ISO8583 converter to JSON, XML, SQL, in a test environment

Posted on 25th Jan 2019 2603 views

Once you have received and successfully deployed your ISO8583 converter from neaPay, deploy and run is easy

1:use/deploy java 8;

2:unpack delivered converter;

3:start converter;

4:start client and server simulators;

5:run transaction 

Run in test mode

Running transaction with the neaPay ISO8583 converter is as easy as running the simulator.

In test mode, you can enable the User Interface and you can do everything by mouse click.

  • 1. Go to the deployment folder where you have unpacked your converter and make sure you have ISS_auth and ACQ_client next to the jre1.7 folders (E.g. C:/neaPayConverter/ISS_auth) 
  • 2. Go into folder ISS_auth and run start_neaPay.bat. For MAC and Linux use A new window called ISO8583 Server Issuer will start. 
  • 3. Press the Start button at the top left of the converter (Green Play button) and wait until the Console shows a message ISS: Issuer starting, TCP Server startingYour Issuer/Converter has started. 
  • 4. Go into folder ACQ_client and run start_neaPay.bat. For MAC and Linux use A new window called ISO8583 Client will start. 
  • 5. Press the Start button at the top left and check the Console messages about a successful connection to the server SYS: Client listener started on port:8181 and that the "Transactions List" window has opened. 
  • 6. Check the Issuer/Converter that it has accepted the connection "Server socket accepted on port ..." 
  • 7. Select a transaction from Acquirer simulator Transactions List and click the Send button. 
  • 8. Check the Acquirer Console that an ISO8583 message has been built and sent to the server. 
  • 9. Check the Issuer that it has parsed the message successfully and built a response. 
  • 10. Check the Acquirer that it has received the response. 
  • 11. Check the Acquirer test case results: 
    ACQ: ************************** TEST PASS ************************** 
    ACQ: RC Received:00 RC Expected:00 
    ACQ: Tests Executed:1 
    ACQ: Tests Passed :1 
    ACQ: Tests Failed :0 
    Congratulations! You have successfully simulated your first transaction with your converter!

If you manged to come this far, you are ready to continue to configure your converter to match your own specification or to do a test run for production, in Docker.

Run in Production


For running in production we reccomend running the converter in headless mode inside a container.

Headless mode is achieved by disabling the UI in If you add this line, you will disable the UI.


By default the converter comes with a Dockerfile and also with a configuration parameter to switch off the UI.

Automatically all output goes to standard out, where it is captured by the container.

Cloud providers usually have solutions for these los, storage or export to data lake analytics.


Deploy with Docker to Test

1. Install docker.


Docker Desktop for Mac (macOS) yes
Docker Desktop for Windows (Microsoft Windows 10)


Deploy with Docker to Production


Step 0. Install tools.

Install unzip

sudo yum install unzip

unzip -v

Platformx86_64 / amd64ARMARM64 / AARCH64IBM Power (ppc64le)IBM Z (s390x)
CentOS yes   yes    
Debian yes yes yes    
Fedora yes   yes    
Ubuntu yes yes yes yes yes

Step 1. Deploy delivery

While on the VM, execute first OR second command, edit to match your delivery link:

wget -O /tmp/ ''

curl -o /tmp/ ''

Step 2. Unpack delivery to location

Assume the delivery is a zip file called You need to unpack this

mkdir ~/neapay/

unzip /tmp/ -d ~/neapay/

Step 3. Run server or several servers

Assume the converter was delivered in a folder called "neapayconverter". All you need to do is execute the script that starts it with Docker. 

cd ~/neapay/neapayconverter


If you have several converters, you either have a composer file or you need to start manually each of the converters

cd ~/neapay/neapayconverter2


The same package can be deployed to the test environment. So it is likely that teh delivery also contains other folders, for example simulators for triggering transactions or web servers in case the converter converts to a web host format. 

They get unpacked anyway. Do not start them, they are not needed. If you do though, nothing bad will happen

Step 4. Redeploys, changes

In case of a redeploy, the procedure can be repeated from start

In case of a configuration change, the script "" can be run again.

The script will automatically find the running container, kill it, remove it, then find the image, remove it, rebuild a new container, and start it. No need to take care of anything about that.&nbsp

Step 5. Container Logs

Run the following command to see the logs of the converter that is called "neapayconverter"

docker logs neapayconverter

If you do not know how your running container is called, run the following command to see running containers

docker ps

Logging options

The converter by default runs in several ways and logging options are available for all.

1. Standalone on windows. Ideal for test situations.

The logs are displayed in standard to the UI console, if activated, or to standard out, if UI is disabled. 

Enhanced logs below can be generated.

2. Standalone on Mac or Linux. This can apply to Test or Production situations

The logs are displayed in standard to the UI console, if activated, or to standard out, if UI is disabled. 

Enhanced logs below can be generated.

UI mode is not suitable for production situations.

3. Container on any platform

All output to system.out

Enhanced logs below can be generated.

Enhanced logs generated automatically

Options to generate HTML or CSV reports are available, as well as sending transactions live (real-time) to another ISO8583 host (warehouse), SQL database or a HTTP host.
