Difficulties running carddemo mainframe app as part of replatforming tutorial

Question

Hello,

I've tried to follow this demo and related toturials:
https://www.youtube.com/watch?v=-sE2jIQ1lrQ
https://docs.aws.amazon.com/m2/latest/userguide/tutorial-templates-ed.html (most relevant)

I've managed to:
* Create the Enterprise Analyzer and Enterprise Developer stacks and run them via AppStream 2.0
* Import the carddemo sample application to the IDE in Enterprise Developer
* Build the application via the IDE (I think)

I am now stuck on defining the Enterprise Server needed to run the carddemo application. In the linked YouTube video, the AWS developer states at 34:29 "I have already created a server called carddemo and configured it correctly", but I have found no reference as to how it can be configured :/ The tutorial link I've pasted above shows how to configure the ES for a different application, called **bank**demo (as opposed to **card**demo).

Without changing too much of the default ES configuration, the server is able to start but it does not seem to run the carddemo application itself (when I show the TN3270 display, I see a generic CICS signon screen rather than the application login screen - and I don't know what credentials the CICS signon screen expects, if that's a prerequisite to get to the actual carddemo application screen).

Any clue how to properly configure the ES to run the carddemo application?

Many thanks!

Lior.

To properly configure and run the CardDemo application in the AWS Mainframe Modernization environment, you'll need to follow these steps:

1. First, ensure you have deployed the CardDemo application that AWS CloudFormation created for you. You can do this through the AWS Mainframe Modernization console:
   - Go to the Applications section
   - Select the CardDemo application (it will have a unique identifier appended to its name)
   - Choose Actions, then Deploy application
   - Select the corresponding runtime environment
   - Click Deploy and wait for it to complete successfully

2. Once deployed, start the application:
   - Select the application again
   - Choose Actions, then Start application
   - Wait until the application status shows as Running

3. In the application details page, you should see a Port number and DNS Hostname. You'll need these to connect to the running application.

4. To connect to the CardDemo application, use a 3270 emulator and specify the DNS hostname and port number you obtained in step 3.

If you're still seeing a generic CICS signon screen instead of the CardDemo login, there might be an issue with the application deployment or configuration. In this case, you may need to:

1. Double-check that you've imported the initial data correctly. This typically involves editing and uploading a JSON file to Amazon S3, then importing it through the console.

2. Verify that all necessary files and packages are present in your project structure, especially in the src/main/java directory. The CardDemo application requires specific packages like com.infotel.carrierdemo.batch and com.infotel.carrierdemo.online.

3. If you're still encountering issues, you might need to consult the specific documentation for the CardDemo application or reach out to AWS support for further assistance.

Remember, the exact steps may vary slightly depending on whether you're using the Micro Focus or Blu Age version of the CardDemo application, so make sure you're following the correct tutorial for your specific setup.
