Hi Ken,
Since I am interested in running effective microservices integration test, I wrote a small application similar to the admin app of Chapter 8.The data model is aroung a Product Entity that is simpler to your Category entity.
1. First, I was running against embedded H2 like admin app of Chapter 8 with Admin DS. With this simple Product Entity I had a problem org.h2.jdbc.JdbcSQLException: Data conversion error converting first record in load.sql to the product table.
I attached a document describing details of this process.
2. I tried unsuccessfully to create my own datasource java:/jboss/datasources/ProductDS instead of using AdminDS, but could not find reliable documentation on how to create a DS with Wildfly-Swarm.
3. Since in-memory databases are never used in production, I wanted to try to use H2 standalone and MySQL running on my PC. Although I found this piece of info, all it talked was about in-memory H2.
There is also this piece of info: related to MySQL but it didn't work for me.
I think it's important to present (probably in Addendum) workinng examples of standalone databases and drivers configuration with Wildfly-Swarm.

Thanks for the input.

I'm presently going through and updating a bunch of examples, some of which are for Chapter 10, that show how to configure WF Swarm to connect to an external MySQL database.

In addition, should cover what you need to configure a DataSource. Although the example uses "h2", you can replace it with "mysql" and provide a MySQL JDBC driver as a dependency of your project.

If you don't think the documentation is clear enough as to how that should work, please raise an issue at
